Using a microphone as an input for real-time audio. How do I extract the currently said phoneme from the audio? I need it for lipsyncing 2d characters.

Basically, my approach would be to:

1. Fetch the real-time audio using a microphone
2. Detect the current phoneme that is being pronounced from the audio.

I have tried looking everywhere for an example or library that could solve this type of problem. Most libraries don't seem to output phonemes from audio.

There is a website that explains how they used machine learning to solve this, however without any code or tutorial on how to do it. .08685/

There is also this cool speech recognition tool called Pocketsphinx, but I cannot seem to find an example of it using Phoneme Recognition yet.

The way I would approach this is to get the word from the audio using Whisper or a similar STT service (the Python Speech Recognition Library is the go-to at the moment), then I would use the CMU Dict Library to provide phonemes for each word.

The phonemes are given using the CMU dictionary - for example DH for the θ phoneme - the th sound in this and that. That is, they are not given in IPA pronunciation - so you may need another layer if you need the phonemes in IPA format. If you need IPA formatted phonemes, then consider the IPA2 library.
