Will this tell me if 2 voices are from the same person if one or both parties are using a voice morphing program? Someone told me that audacity would tell whether or not 2 voices are the same regardless if they are using a voice morph or not.

Thank you!

No. That’s probably a job best handled by a skilled human (if it can be done at all). I’d guess it would be best to focus on speech patterns, pace, vocabulary, etc. i.e., Does the person say “ax”, instead of “ask”… Things like that.

Thank you for the reply but what is exactly the purpose of Audacity?

Audacity is a multi-track audio editor. It has not been designed for forensic analysis or voice identification.

Thank you for the reply but what is exactly the purpose of Audacity?

A few examples:

  • You can boost the bass in your music files, or add other effects such as reverb or echo.
  • You can shorten a song by fading-out half-way through.
  • You can “bleep out” or mute dirty words in a song or movie soundtrack.*
  • You can make a crossfaded “mix tape” (or MP3, etc.) where the songs overlap with beginning of the 2nd fades-in while the 1st song fades-out.
  • You can make a voice-over recording, or a commentary, or record an audio book.
  • You can record yourself singing and mix-in your voice singing-along to your favorite song.

  • Audacity does not work with video and it won’t open the audio from a commercial copy-protected DVD.
