How do I use this to detect the start of a speech segment?

[StanSilas]

Q1) can I use this on a .wav/.mp3 files? Q2) how to use this to to detect the beginning of any voice activity in the file.

Hi @StanSilas , I am glad it will be useful for you.

Q1: you can use this to a file(wav/mp3), you should change the interface a little. for example:

fp = open('test.wav')
data = fp.read()

then you can do vad using data

Q2: if you solve Q1 successfully, you will find you can do VAD at any time.

you can deliver the voice data to this function

active = vad.is_speech(chunk, RATE)
