I have a bunch of audio files, each with a 'tring tring or hold music'
and then the actual conversation. slash
What is the best way to detect and remove the the hold music and the
tring tring from the audio file so that I will have clean files with
just 'conversation' ?

So that the speech to text transcription might be better.

Hello,

Well, in fact, you should start with clean voices, and then, add
modified voices, with noise add, and other deformations. (with
voice-corpus-tool)

you made a lot of clean voices, slash
you recorded many noisy road sounds (ex : 10s each) slash
you duplicated those voices, adding this noise inside. (augment
param in voice-corpus-tool)

Finally, you obtain a model working in your own environnment.

function of SOX slash
(but it's not miraculous with noisy voice : sox will not only remove
noise, it will surely remove important parts of your voice... Have a
try.
