Voice Interface Technology Mimics Human Hearing
earSmart enhances quality and suppresses background noise by studying the brain's auditory pathways.
earSmart, developed by the California-based company Audience, is a voice processor technology used by Siri and 50 different mobile phone models. It enhances voice quality and suppresses background noise by mimicking the brain’s auditory pathways.
To reduce peripheral noise sufficiently to support voice interfaces, Audience took a science-based design approach by figuring out and copying how the brain separates sounds and then applying that in the development and improvement of their product. The earSmart system makes phone calls clearer and easier to understand in noisy environments by separating sound from different sources. It works like human hearing to distinguish sounds, enhance the voice signal and filter out background noise.
