Hi,
This is my point - to save recording to a file and run executable that compares it against the pre-recorded original. It would have not been an easy task, but I found the software, which can do that quite well.
That's another point: if I have voice quality testing software then I don't need speech recognition for this particular case.
And you are right: I am trying to test the voice quality of the system by playing a sound through the phone mic and comparing it to the original sound recording.
