Developers and enterprises now have immediate access to state-of-the-art generative and semantic models purpose-built for RAG (Retrieval-Augmented Generation) and agentic AI workflows on Azure AI Foundry to: Deploy high-performance LLMs and semantic search engines directly into production Build faster, more scalable, and multilingual RAG pipelines Leverage models that are optimized for enterprise workloads in finance, healthcare, government, and manufacturing Cohere Embed 4: High-Performance Embeddings for Search & RAG Accompanying Command A is Cohere’s Embed 4, a cutting-edge embedding model ideal for retrieval-augmented generation pipelines and semantic search. Embed 4 (the latest evolution of Cohere’s Embed series) converts text – and even images – into high-dimensional vector representations that capture semantic meaning. It’s a multi-modal, multilingual embedding model designed to provide recall and relevance in vector search, text classification, and clustering tasks. What makes Embed 4 stand out? 100+ Language Support: This model is truly global – it supports well over 100 languages for text embeddings. You can encode queries and documents in many languages (Arabic, Chinese, French, Hindi, etc.) into the same vector space, enabling cross-lingual search out of the box. For example, a question in Spanish can retrieve a relevant document originally in English if their ideas align semantically. Multi-Modal Embeddings: Embed 4 is capable of embedding not only text but also images. This means you can use it for multimodal search scenarios – e.g. indexing both textual content and images and allowing queries across them. Under the hood, the model has an image encoder; the Azure AI Foundry SDK provides an ImageEmbeddingsClient to generate embeddings from images. With this, you could embed a diagram or a screenshot and find text documents that are semantically related to that image’s content. Matryoshka Embeddings (Scalable Dimensions): A novel feature in Cohere’s Embed 4 is Matryoshka Representation Learning, which produces embeddings that can be truncated to smaller sizes with minimal loss in fidelity. In practice, the model can output a high-dimensional vector (e.g. 768 or 1024 dims) but you have the flexibility to use just the first 64, 128, 256, etc. dimensions if needed. These “nested” embeddings mean you can choose a vector size that balances accuracy vs. storage/query speed – smaller vectors save memory and compute while still preserving most of the semantic signal. This is great for enterprise deployments where vector database size and latency are critical. Enterprise Optimizations: Cohere has optimized Embed 4 for production use. It supports int8 quantization and binary embedding output natively, which can drastically reduce storage footprint and speed up similarity search with only minor impact on accuracy (useful for very large indexes). The model is also trained on massive datasets (including domain-specific data) to ensure robust performance on noisy enterprise text. It achieves state-of-the-art results on benchmark evaluations like MTEB, meaning you get retrieval quality on par with or better than other leading embeddings models (OpenAI, Google, etc.). For instance, Cohere’s previous embed model was top-tier on cross-language retrieval tasks and Embed4 further improves on that foundation. Cohere Command A: Generative Model for Enterprise AI Command A is Cohere’s latest flagship large language model, designed for high-performance text generation in demanding enterprise scenarios. It’s an instruction-tuned, conversational LLM that excels at complex tasks like multi-step reasoning, tool use (function calling), and retrieval-augmented generation. Command A features a massive 111B parameter Transformer architecture with 256K token context length – enabling it to handle extremely large inputs (hundreds of pages of text) in a single prompt without losing coherence. Source for above benchmarks : Introducing Command A: Max performance, minimal compute Some key capabilities of Command A include: Long Context (256K tokens): Using an innovative attention architecture (sliding window + global attention), Command A can ingest up to 256,000 tokens of text in one go. This enables use cases like analyzing lengthy financial reports or entire knowledge bases in a single prompt. Enterprise-Tuned Generation: Command A is optimized for business applications – it’s excellent at instructions, summarization, and especially RAG workflows where it integrates retrieved context and even cites sources to mitigate hallucinations. It supports tool calling (function calling) out-of-the-box so it can interact with external APIs or data sources as part of an Azure AI Agent. Multilingual Proficiency: Command A is good at multilingual use cases (covering all major business languages, with near leading performance in Japanese, Korean, and German). Efficient Deployment: Despite its size, Command A is engineered for efficiency – it delivers 150% higher throughput than its predecessor (Command R+ 08-2024) and requires only 2× A100/H100 GPUs to run. In practice this means lower latency. It also supports streaming token output, so applications can start receiving the response as it’s generated, keeping interaction latency low. Real-World Use Cases for Command A + Embed 4 With both a powerful generative model and a state-of-the-art embedding model at your fingertips, developers can build advanced AI solutions. Here are some real-world use cases unlocked by Command A and Embed 4 on Azure: Financial Report Summarization (RAG): Imagine ingesting thousands of pages of financial filings, earnings call transcripts, and market research into a vector store. Using Embed 4, you can embed and index all this text. When an analyst asks “What were the key revenue drivers mentioned in ACME Corp’s Q1 2025 report?”, you use the query embedding to retrieve the most relevant passages. Command A (with its 256K context) can then take those passages and generate a concise summary or answer with cited evidence. The model’s long context window means it can consider all retrieved chunks at once, and its enterprise tuning ensures factual, business-appropriate summaries. Legal Research Agent (Tool Use + Multilingual): For example a multinational law firm handling cross-border mergers and acquisitions. They have a vast repository of legal documents in multiple languages. Using Embed 4, they index these documents, creating multilingual embeddings. When a lawyer researches a specific legal precedent related to a merger in Germany, they can query in English. Embed 4 retrieves relevant German documents, and Command A summarizes key points, translates excerpts, and compares legal arguments across jurisdictions. Furthermore, Command A leverages tool calling (utilizing agentic capabilities) to retrieve additional information from external databases, such as company registration details and regulatory filings, integrating this data into its analysis to provide a comprehensive report. Technician Knowledge Assistant (RAG + Multilingual): Think of a utilities company committed to operational excellence, managing a vast network of critical equipment, including power generators, transformers, and distribution lines. They can leverage Command A, integrated with Embed 4, to index a comprehensive repository of equipment manuals, maintenance records, and sensor data in multiple languages. This enables technicians and engineers to access critical knowledge instantly. Technicians can ask questions in their native language about specific equipment issues, and Command A retrieves relevant manuals, troubleshooting guides, and past repair reports. It also guides technicians through complex maintenance procedures step-by-step, ensuring consistency and adherence to best practices. This empowers the company to optimize maintenance processes, improve overall equipment reliability, and enhance communication, ultimately achieving operational excellence. Multimodal Search & Indexing: With Embed 4’s image embedding capability, you can build search systems that go beyond text. For instance, a media company could index their image library by generating embeddings for each image (using Azure’s Image Embeddings client) and also index captions/descriptions. A user could then supply a query image (or a textual description) and retrieve both images and articles that are semantically similar to the query. This is useful for scenarios like finding slides similar to a given diagram, searching scanned invoices by content, or matching user-uploaded photos to reference documents. Getting Started: Deploying via Azure AI Foundry In Azure AI Foundry, Embed 4 can be used via the Embeddings API to encode text or images into vectors. Each text input is turned into a numeric vector (e.g. 1024-dimension float array) that you can store in a vector database or use for similarity comparisons. The embeddings are normalized for cosine similarity by default. You can also take advantage of Azure’s vector index or Azure Cognitive Search to directly build vector search on top of these model outputs. Image Source : Introducing Embed 4: Multimodal search for business One of the biggest benefits of using Azure AI Foundry is the ease of deployment for these models. Cohere’s Command A and Embed 4 are available in the model catalog – you can find their model cards and deploy them in just a few clicks. Azure Foundry supports serverless API endpoints for these models, meaning Microsoft hosts the inference infrastructure and scales it for you (with pay-as-you-go billing). Integration with Azure AI Agent Service: If you’re building an AI agent (a system that can orchestrate models and tools to perform tasks), Azure AI Agent Service makes it easy to incorporate these models. In the Agent Service, you can simply reference the deployed model by name as the agent’s reasoning LLM. For example, you could specify an agent that uses CohereCommandA as its model, and add tools like Azure Cognitive Search. The agent can then handle user requests by, say, using a Search tool (powered by Embed 4 vector index) and then passing the results to Command A for answer formulation – all managed by the Azure Agent framework. This lets you build production-grade agentic AI workflows that leverage Cohere’s models with minimal plumbing. In short, Azure provides the glue to connect Command A + Embed 4 + Tools into a coherent solution.

In an age where digital transformation influences nearly every aspect of business, companies are actively seeking innovative ways to differentiate their customer interactions. Traditional text-based chatbots, while helpful, often leave users wanting a more natural, personalized, and efficient experience. Imagine hosting a virtual brand ambassador—a digital twin of yourself or your organization’s spokesperson—capable of answering customer queries in real time with a lifelike voice and expressive 2D or 3D face. This is where Project Maria comes in. Project Maria is an internal Microsoft initiative that integrates cutting-edge speech-to-text (STT), text-to-speech (TTS), large language model and avatar technologies. Using Azure AI speech and custom neural voice models, it seeks to create immersive, personalized interactions for customers—reducing friction, increasing brand loyalty, and opening new business opportunities in areas such as customer support, product briefings, digital twins, live marketing events, safety briefings, and beyond. In this blog post, we will dive into: The Problem and Rationale for evolving beyond basic text-based solutions. Speech-to-Text (STT), Text-to-Speech (TTS) Pipelines, Azure OpenAI GPT-4o Real-Time API that power natural conversations. Avatar Models in Azure, including off-the-shelf 2D avatars and fully customized custom avatar Neural Voice Model Creation, from data gathering to training and deployment on Azure. Security and Compliance considerations for handling sensitive voice assets and data. Use Cases from customer support to digital brand ambassadors and safety briefings. Real-World Debut of Project Maria, showcased at the AI Leaders’ Summit in Seattle. Future Outlook on how custom avatar will reshape business interactions, scale presence, and streamline time-consuming tasks. If you’re developing or considering a neural (custom) voice + avatar models for your product or enterprise, this post will guide you through both conceptual and technical details to help you get started—and highlight where the field is heading next. 1. The Problem: Limitations of Text-Based Chatbots 1.1 Boredom and Fatigue in Text Interactions Text-based chatbots have come a long way, especially with the advent of powerful Large Language Models (LLMs) and Small Large Models (SLMs). Despite these innovations, interactions can still become tedious—often requiring users to spend significant personal time crafting the right questions. Many of us have experienced chatbots that respond with excessively verbose or repetitive messages, leading to boredom or even frustration. In industries that demand immediacy—like healthcare, finance, or real-time consumer support—purely text-based exchanges can feel slow and cumbersome. Moreover, text chat requires a user’s full attention to read and type, whether in a busy contact center environment or an internal knowledge base where employees juggle multiple tasks. 1.2 Desire for More Engaging and Efficient Modalities Today’s users expect something closer to human conversation. Devices ranging from smartphones to smart speakers and in-car infotainment systems have normalized voice-based interfaces. Adding an avatar—whether a 2D or 3D representation—deepens engagement by combining speech with a friendly visual persona. This can elevate brand identity: an avatar that looks, talks, and gestures like your company’s brand ambassador or a well-known subject-matter expert. 1.3 The Need for Scalability In a busy customer support environment, human representatives simply can’t handle an infinite volume of conversations or offer 24/7 coverage across multiple channels. Automation is essential, yet providing high-quality automated interactions remains challenging. While a text-based chatbot might handle routine queries, a voice-based, avatar-enabled agent can manage more complex requests with greater dynamism and personality. By giving your digital support assistant both a “face” and a voice aligned with your brand, you can foster deeper emotional connections and provide a more genuine, empathetic experience. This blend of automation and personalization scales your support operations, ensuring higher customer satisfaction while freeing human agents to focus on critical or specialized tasks. 2. The Vision: Project Maria’s Approach Project Maria addresses these challenges by creating a unified pipeline that supports: Speech-to-Text (STT) for recognizing user queries quickly and accurately. Natural Language Understanding (NLU) layers (potentially leveraging Azure OpenAI or other large language models) for comprehensive query interpretation. Text-to-Speech (TTS) that returns highly natural-sounding responses, possibly in multiple languages, with customized prosody and style. Avatar Rendering, which can be a 2D animated avatar or a more advanced 3D digital twin, bringing personality and facial expressions to the conversation. By using Azure AI Services—particularly the Speech and Custom Neural Voice offerings—can deliver brand-specific voices. This ensures that each brand or individual user’s avatar can match (or approximate) a signature voice, turning a run-of-the-mill voice assistant into a truly personal digital replicas 3. Technical Foundations 3.1 Speech-to-Text (STT) At the heart of the system is Azure AI Services for Speech, which provides: Real-time transcription capabilities with a variety of languages and dialects. Noise suppression, ensuring robust performance in busy environments. Streaming APIs, critical for real-time or near-real-time interactions. When a user speaks, audio data is captured (for example, via a web microphone feed or a phone line) and streamed to the Azure service. The recognized text is returned in segments, which the NLU or conversation manager can interpret. 3.1.1 Audio Pipeline Capture: The user’s microphone audio is captured by a front-end (e.g., a web app, mobile app, or IoT device). Pre-processing: Noise reduction or volume normalization might be applied locally or in the cloud, ensuring consistent input. Azure STT Ingestion: Data is sent to the Speech service endpoint, authenticated via subscription keys or tokens (more on security later). Result Handling: The recognized text arrives in partial hypotheses (partial transcripts) and final recognized segments. Project Maria (Custom Avatar) processes these results to understand user intent 3.2 Text-to-Speech (TTS) Once an intent is identified and a response is formulated, the system needs to deliver speech output. Standard Neural Voices: Microsoft provides a wide range of prebuilt voices in multiple languages. Custom Neural Voice: For an even more personalized experience, you can train a voice model that matches a brand spokesperson or a distinct voice identity. This is done using your custom datasets, ensuring the final system speaks exactly like the recorded persona. 3.2.1 Voice Font Selection and Configuration In a typical architecture: The conversation manager (which could be an orchestrator or a custom microservice) provides the text output to the TTS service. The TTS service uses a configured voice font—like en-US-JennyNeural or a custom neural voice ID (like Maria Neural Voice) if you have a specialized voice model. The synthesized audio is returned as an audio stream (e.g., PCM or MP3). You can play this in a webpage directly or in a native app environment. Azure OpenAI GPT-4o Real-Time API integrates with Azure's Speech Services to enable seamless interactions. First, your speech is transcribed in near real time. GPT-4o then processes this text to generate context-aware responses, which are converted to natural-sounding audio via Azure TTS. This audio is synchronized with avatar models to create a lifelike, engaging interface 3.3 Real-Time Conversational Loop Maria is designed for real-time or text to speech conversations. The user’s speech is continuously streamed to Azure STT. The recognized text triggers a real-time inference step for the next best action or response. The response is generated by Azure OpenAI model (like GPT-4o) or other LLM/SLM The text is then synthesized to speech, which the user hears with minimal latency. 3.4 Avatars: 2D and Beyond 3.4.1 Prebuilt Azure 2D Avatars Azure AI Speech Services includes an Avatar capability that can be activated to display a talking head or a 2D animated character. Developers can: Choose from prebuilt characters or import basic custom animations. Synchronize lip movements to the TTS output. Overlay brand-specific backgrounds or adopt transparency for embedding in various UIs. 3.4.2 Fully Custom Avatars (Customer Support Agent Like Maria) For organizations wanting a customer support agent, subject-matter expert, or brand ambassador: Capture: Record high-fidelity audio and video of the person you want to replicate. The more data, the better the outcome (though privacy and licensing must be considered). Modeling: Use advanced 3D or specialized 2D animation software (or partner with Microsoft’s custom avatar creation solutions) to generate a rigged model that matches the real person’s facial geometry and expressions. Integration: Once the model is rigged, it can be integrated with the TTS engine. As text is converted to speech, the avatar automatically animates lip shapes and facial expressions in near real time. 3.5 Latency and Bandwidth Considerations When building an interactive system, keep an eye on: Network latency: Real-time STT and TTS require stable, fast connections. Compute resources: If hosting advanced ML or high concurrency, scaling containers (e.g., via Docker and Kubernetes) is critical. Avatars: Real-time animation might require sending frames or instructions to a client’s browser or device. 4. Building the Model: Neural Voice Model Creation 4.1 Data Gathering To train a custom neural voice, you typically need: High-quality audio clips: Ideally recorded in a professional studio to minimize background noise, with the same microphone setup throughout. Matching transcripts for each clip. Minimum data duration: Microsoft recommends a certain threshold (e.g., 300+ utterances, typically around 30 minutes to a few hours of recorded speech, depending on the complexity of the final voice needed). 4.2 Training Process Data Upload: Use the Azure Speech portal or APIs to upload your curated dataset. Model Training: Azure runs training jobs that often require a few hours (or more). This step includes: Acoustic feature extraction (spectrogram analysis). Language or phoneme modeling for the relevant language and accent. Prosody tuning, ensuring the voice can handle various styles (cheerful, empathetic, urgent, etc.). Quality Checks: After training, you receive an initial voice model. You can generate test phrases to assess clarity, intonation, and overall quality. Iteration: If the voice quality is not satisfactory, you gather more data or refine the existing data (removing noisy segments or inaccurate transcripts). 4.3 Deployment Once satisfied with the custom neural voice: Deploy the model to an Azure endpoint within your subscription. Configure your TTS engine to use the custom endpoint ID instead of a standard voice. 5. Securing Avatar and Voice Models Security is paramount when personal data, brand identity, or intellectual property is on the line. 5.1 API Keys and Endpoints Azure AI Services requires an API key or an OAuth token to access STT/TTS features. Store keys in Azure Key Vault or as secure environment variables. Avoid hard-coding them in the front-end or source control. 5.2 Access Control Role-Based Access Control (RBAC) at both Azure subscription level and container (e.g., Docker or Kubernetes) level ensures only authorized personnel can deploy or manage the containers running these services. Network Security: Use private endpoints if you want to limit exposure to the public internet. 5.3 Intellectual Property Concerns Avatar and Voice Imitation: A avatar model and custom neural voice that mimics a specific individual must be authorized by that individual. Azure has a verification process in place to ensure consent. Data Storage: The training audio data and transcripts must be securely stored, often with encryption at rest and in transit. 6. Use Cases: Bringing It All Together 6.1 Customer Support A digital avatar that greets users on a website or mobile app can handle first-level queries: “Where can I find my billing information?” “What is your return policy?” By speaking these answers aloud with a friendly face and voice, the experience is more memorable and can reduce queue times for human agents. If the question is too complex, the avatar can seamlessly hand off to a live agent. Meanwhile, transcripts of the entire conversation are stored (e.g., in Azure Cosmos DB), enabling data analytics and further improvements to the system. 6.2 Safety Briefings and Public Announcements Industries like manufacturing, aviation, or construction must repeatedly deliver consistent safety messages. A personal avatar can recite crucial safety protocols in multiple languages, ensuring nothing is lost in translation. Because the TTS voice is consistent, workers become accustomed to the avatar’s instructions. Over time, you could even create a brand or site-specific “Safety Officer” avatar that fosters familiarity. 6.3 Digital Twins at Live Events Suppose you want your company’s spokesperson to simultaneously appear at multiple events across the globe. With a digital twin: The spokesperson’s avatar and voice “present” in real time, responding to local audience questions. This can be done in multiple languages, bridging communication barriers instantaneously. Attendees get a sense of personal interaction, while the real spokesperson can focus on core tasks, or appear physically at another event entirely. 6.4 AI Training and Education In e-learning platforms, a digital tutor can guide students through lessons, answer questions in real time, and adapt the tone of voice based on the difficulty of the topic or the student’s performance. By offering a face and voice, the tutor becomes more engaging than a text-only system. 7. Debut: Maria at the AI Leaders Summit in Seattle Project Maria had its first major showcase at the AI Leaders Summit in Seattle last week. We set up a live demonstration: Live Conversations: Attendees approached a large screen that displayed Maria’s 2D avatar. On-the-Fly: Maria recognized queries with STT, generated text responses from an internal knowledge base (powered by GPT-4o or domain-specific models), then spoke them back with a custom Azure neural voice. Interactive: The avatar lip-synced to the output speech, included animated gestures for emphasis, and even displayed text-based subtitles for clarity. The response was overwhelmingly positive. Customers praised the fluid voice quality and the lifelike nature of Maria’s avatar. Many commented that they felt they were interacting with a real brand ambassador, especially because the chosen custom neural voice had just the right inflections and emotional range. 8. Technical Implementation Details Below is a high-level architecture of how Project Maria might be deployed using containers and Azure resources. Front-End Web App: Built with a modern JavaScript framework (React, Vue, Angular, etc.). Captures user audio through the browser’s WebRTC or MediaStream APIs. Connects via WebSockets or RESTful endpoints for STT requests. Renders the avatar in a <canvas> element or using a specialized avatar library. Backend: Containerized with Docker. Exposes endpoints for STT streaming (optionally passing data directly to Azure for transcription). Integrates with the TTS service, retrieving synthesized audio buffers. Returns the audio back to the front-end in a continuous stream for immediate playback. Avatar Integration: The back-end or a specialized service handles lip-sync generation (e.g., via phoneme mapping from the TTS output). The front-end renders the 2D or 3D avatar in sync with the audio playback. This can be done by streaming timing markers that indicate which phoneme is currently active. Data and Conversation Storage: Use an Azure Cosmos DB or a similar NoSQL solution to store transcripts, user IDs, timestamps, and optional metadata (e.g., conversation sentiment). This data can later be used to improve the conversation model, evaluate performance, or train advanced analytics solutions. Security: All sensitive environment variables (like Azure API keys) are loaded securely, either through Azure Key Vault or container orchestration secrets. The system enforces user authentication if needed. For instance, an internal HR system might restrict the avatar-based service to employees only. Scaling: Deploy containers in Azure Kubernetes Service (AKS), setting up auto-scaling to handle peak loads. Monitor CPU/memory usage, as well as TTS quota usage. For STT, ensure the service tier can handle simultaneous requests from multiple users. 9. Securing Avatar Models and Voice Data 9.1 Identity Management Each avatar or custom neural voice is tied to a specific subscription. Using Azure Active Directory (Azure AD), you can give fine-grained permissions so that only authorized DevOps or AI specialists can alter or redeploy the voice. 9.2 API Gateways and Firewalls For enterprise contexts, you might place an API Gateway in front of your containerized services. This central gateway can: Inspect requests for anomalies, Enforce rate-limits, Log traffic to meet compliance or auditing requirements. 9.3 Key Rotation and Secrets Management Frequently rotates keys to minimize the risk of compromised credentials. Tools like Azure Key Vault or GitHub’s secret storage features can automate the rotation process, ensuring minimal downtime. 10. The Path Forward: Scaling Custom Avatar 10.1 Extended Personalization While Project Maria currently focuses on voice and basic facial expressions, future expansions include: Emotion Synthesis: Beyond standard TTS expressions (friendly, sad, excited), we can integrate emotional AI to dynamically adjust the avatar’s tone based on user sentiment. Gesture Libraries: 2D or 3D avatars can incorporate hand gestures, posture changes, or background movements to mimic a real person in conversation. This reduces the “uncanny valley” effect. 10.2 Multilingual, Multimodal As businesses operate globally, multilingual interactions become paramount. We have seen many use cases to: Auto-detect language from a user’s speech and respond in kind. Offer real-time translation, bridging non-English speakers to brand content. 10.3 Agent Autonomy Systems like Maria won’t just respond to direct questions; they can initiate proactivity: Send voice-based notifications or warnings when critical events happen. Manage long-running tasks such as scheduling or triaging user requests, akin to an “executive assistant” for multiple users simultaneously. 10.4 Ethical and Social Considerations With near-perfect replicas of voices, there is a growing concern about identity theft, misinformation, and deepfakes. Companies implementing digital twins must: Secure explicit consent from individuals. Implement watermarking or authentication for voice data. Educate customers and employees on usage boundaries and disclaimers 11.
