How can I do audio transcription with AI on Windows 11?

Kaldi is a professional-grade, open-source speech recognition toolkit widely used in scientific research and academia. Due to its flexibility and accuracy, it is often regarded as the gold standard among audio transcription tools.

Why choose it: If you need a powerful, customizable audio transcription tool that runs offline and gives you complete control over models and parameters, Kaldi offers research-grade performance—even though its learning curve is relatively steep.

How to use:

1. Install the software and download the pre-trained model for the target language.

2. Convert the audio to 16 kHz mono WAV format for preprocessing:

ff mpeg -i input.mp4 -ar 16000 -ac 1 output.wav

3. Run the transcription script using the pre-trained model.

4. Extract the text output from the generated file.

This is one of the best transcription tools available today, but it’s designed primarily for researchers and developers, not general users. If you’re looking for professional-grade results and don’t mind configuring the settings, it’s worth a try; however, for basic needs, a simpler program might be a better fit for you.
