This is how KishKish promotes its voice stress analysis (VSA) plugin for SAM, a voice Skype conversation recorder. The VSA is claimed to tell if someone over the softphone is tensed, and possibly lying.
Here’s how it works: KishKish SAM recorder saves the call, then replays it by filtering the audio conversation to find out stress peaks within interlocutors’ voice.
According to Skype’s blog, “there’s strong interest from the developer community in having easier access to the voice stream to develop exactly this kind of applications, and this will be much more accessible to developers in the future versions with the voice API.”
Meanwhile an enhanced version of the KishKish lie detector is expected to come. Less playback, closer to a real-time scan.
