Japanese mobile operator KDDI au is adding Melodis Corporation's Midomi singing search technology to its Lismo mobile music platform.

Midomi, powered by Melodis's proprietary multimodal adaptive recognition system (MARS), lets users search for and discover songs by singing or humming them. Acknowledging that there are a lot of mediocre and bad singers out there, Midomi was designed to return accurate results even if the user sings or hums off-key, has trouble with the lyrics or messes up the tempo.

KDDI is working with mobile communications solutions provider Sockets to integrate Midomi into its music offering.
