Project description
Programmer services are required. You need to write a program in which you need to insert an audio file (human conversation) and so that the program can determine the characteristic of the signal and highlight the main tone. The programming language is not important.
I also have a video file that shows an example of how the program should look and there are all the manuals for this work.
