Voice processor mimics human hearing to nix noise

A voice processor based on the intelligence of the human hearing system has been introduced by startup company Audience. Mobile handset manufacturers, faced with a dilemma of increased churn and customer dissatisfaction regarding the quality of mobile calls, now have an opportunity to do something major about it.

The Audience Voice Processor mimics the entire audio pathway!from cochlea to brainstem, thalamus and cortex!to deliver a unique grouping and processing of complex mixtures of sound. It is the only solution today that processes signals in the same manner people actually perceive specific sounds!and is able to identify and suppress noise sources accurately as a result.

According to Audience CEO Peter Santos, "Today there is an acoustic noise roadblock. Attempts are being made in the industry to take care of such stationary noise as fans, yet most noise is not stationary. Instead, the rapidly changing nature of most noise is resistant to solutions!until now."

Audience's technology receives complex sound at overlapping frequencies and organizes it into individual sources!just as people hear it. Whether the noise is within the caller's environment or remote, the processor groups all sound sources instantaneously, suppressing noise and delivering clear voice.

Other benefits
Not only does Audience address the increased frustration of poor quality phone calls, it enables phones to do what they are supposed to do!power down while the user is not talking. When noise exists in the environment, the phone continues to burn battery power and network capacity. Once the Audience Voice Processor is employed, the phone powers down as it is supposed to. Another benefit is the clarity that an Interactive voice response system can receive when Audience is used. The major benefit, however, could be stopping the runaway churn that this talking place as mobile phone users attempt to find voice quality in their calls.

Audience is currently sampling its A1010 Voice Processor chip to handset manufacturers.
