Home finding speed and tone of speech in an audio using python
 Given an audio , I want to calculate the pace of the speech. i.e how fast or slow is it. Currently I am doing the following: - convert speech to text and obtaining a transcript (using a free tool). - count number of words in transcript. - calculate length or duration of file. - finally, pace = (number of words in transcript / duration of file). However the accuracy of the pace obtained is dependent purely on transcription , which I think is an unnecessary step. Is there any python-library/sox/ffmpeg way that will enable me to to calculate, in a straightforward way,the speed/pace of talk in an audio dominant Pitches/tones of that audio?
