Say I'm recording a radio DJ, and the final results in an audio file
contain: slash
music --- some music --- speech/voice -- music--- speech --- speech ---
speech --- hold music --- end of audio slash
(here speech-music is assumed to be non overlapping or marginally
overlapping.)

Q1. How do I ignore the non speech and extract only the speech portions
of the audio? slash
i.e I want my final audio to have only the speech portions.

Q2. How does deep speech currently handle music when doing
speech-recognition??

Q3. is there any pre trained model for detecting the onset of speech or
portions of speech in an audio?

1. Use a Voice Activity Detection (VAD) tool.

2. It doesn't. Transcription results for music will not make sense.

3. There are several available VAD tools. The WebRTC project has one,
for example. There's a topic here on Discourse that mentions other
tools, but I don't remember where it is.
