The Ring 'n Sing service has been developed by VoxGen in association with Vocability. It is a phone-based game that uses a pitch-tracking algorithm to compare different voices and score each one against a professional artist. For the user, this means calling a number and selecting the song from those on offer. After listening to the song, they then sing their version down the line. The system compares the two renditions before giving a mark out of one through 10.

The application is customizable.

Ring 'n Sing has been developed by VoxGen and the technology works for any voice and any song in any language.
