Audience announced that its voice processor, based on the intelligence of the human hearing system, powers NTT DoCoMo's mobile phone, the Sharp SH705iII, released in April.

The Audience A1010, claimed to be the industry's first voice processor, supports Sharp's Triple Kukkiri Talk by providing powerful and robust noise suppression, voice equalizer, and voice stretch performance. The voice processor instantaneously reduces multiple noise sources, such as airport PA systems, restaurant noise, car noise and street noise.

The voice processor is also said to be the first custom IC that is modeled after the human hearing system. By understanding the auditory pathway -- from the cochlea to the brainstem to the thalamus and cortex -- Audience claims to be the first company to deliver a commercial product based on the science of auditory scene analysis (ASA), or the grouping and processing of complex mixtures of sound. Because the voice processor handles signals the way people actually perceive specific sounds, it is able to identify and suppress noise sources in an efficient and accurate manner.
