MUMBAI: US broadcaster NBC has announced an online complement for its upcoming reality show The Voice.

"The Voice Online Audition Tool" -- Available at NBC.com will allow Users to showcase their talents from home via a personal computer and webcam as the tool records the performance and rates it based on pitch and expression.

While the show's casting team is searching the US, working with music industry experts and hosting casting calls in an effort to find the nation's top talent, "The Voice Online Audition Tool" takes the process one step further -- allowing the show to find potential contestants right in their own homes via the use of a personal computer and a webcam.

NBC executive VP, alternative programming and production Paul Telegdy said, "This unique interactive online experience that provides immediate feedback and scoring is an evolution in the casting process. This technology will exponentially expand our reach but, of course, only the best of the best will make it on to the show. The possibility that the next global superstar could be discovered through this innovative tool is incredibly exciting to all of us involved."

The tool records performances and then rates them on a scale from 1 to 10 based on pitch and expression. Once submitted, eligible performances will be showcased on NBC.COM; they can then be rated by fans and shared via social networks.

The Voice casting team will review submitted videos, seeking the ones that boast the highest scores and the best performances. Users interested in a chance to compete in this season of the show are encouraged to submit their best performances by 1 March, the current casting cut-off.

Unlike an open casting call, users of the online tool have the opportunity to practice and hone their performance, rate themselves against others, work to raise their score and submit multiple times.
