How to make a word or letter in an audio file and cut it out evenly?

Answer 1

First, perform this action:

Write down on a piece of paper (or in a file) the exact time of the beginning of the word and the exact time of the end of the word. Install ffmpeg-python and cut exactly what you need.
You can also use neural networks. But there are 2 minuses:
1) They still do not work well enough, even in large companies (Siry, Alice)
2) You will not figure it out.
