Azure Cognitive Search AMA: Vector search, Azure OpenAI Service, generative apps, plugins & more

That somewhat depends on what the use case is. For example, a very common one is to be able to convert audio to text (e.g. transcription) which is then searchable. For this there is Azure Speech Services (https://learn.microsoft.com/en-us/azure/ai-services/speech-service/overview) as well as the introduction of OpenAI Whisper (https://techcommunity.microsoft.com/t5/azure-ai-services-blog/openai-whisper-is-coming-soon-to-azure-openai-service-and-azure/ba-p/3876671). Once it is in text format you can then use typical text models such as Azure OpenAI Ada 002. There are also numerous models that can be used to create embeddings based on other audio types.
