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.
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.
