Our customer have an idea to built an IVR service to provide a karaok
competition. They have a karaok (may be in wave or other format). The
user can dial into IVR and select the song that he/she want to sing.
So, the engine play melody sound in background and let user sing
along. The system will record the sound of user and automatically
compare with the sound of orignal singer. Then the system report the
score to the user.
We already have an IVR engine and karaok media. I'm looking for any
software that can compare a sound of competitor VS singer and produce
a rating score. Here is my questions:
1. does it has a software that can compare voice/sound for this
purpose.
2. How does it accurated? Can it replace the human effort?

Thanks in advance,
Skon L.
