separate voices of different people

You mean something like THIS!(Tap Here/Click Here) 

hello, thank you very much, the question is if in an audio you can listen to the voice of one person and eliminate that of another so that the audio is shorter (the two voices are separated in time but it is only one track), even if it is me It would be worth it to put automatic marks for me to delete manually or to identify the frequencies

Are they on one track, and about at the same level? If they are, then there's no automatic way to do this at all. In order to answer your question properly, we'd need to know what the basic circumstances of your recording are...
