Apple to Rate Your Karaoke Singing on Your iPhone?
Apple has published a very interesting patent application in which they explore how to provide a Karaoke experience on the iPhone. Not only would users be able to sing along with their favorite songs, but Apple wants to give real-time feedback to singers letting them know how they are doing.
The systems and methods for providing users with real-time feedback while they are singing on key/pitch and providing real-time feedback to the user while the karaoke song is being sung. The feedback will be positive feedback if user is on key/pitch and it will be negative feedback if user is off key/pitch.
The patent application addresses "one of the biggest obstacles faced by amateur sings: singing on key/pitch". Apple suggests that this system could actually improve the quality of people's singing. One novel way to accomplish this would be to measure the pitch of the singer's voice and if it were to be too low, the device could exaggerate the low pitch of the user's own voice to encourage them to sing higher.
Apple clearly depicts pictures of the iPhone's iPod application with an additional menu option for "Karaoke". The interface for the Karaoke section is also shown above. We don't know if Apple will pursue this option in a future version of the iPhone software, but it's a fun and interesting proposition.
