Robust voice detector for receive-side automatic gain control

摘要

A voice detector improves voice output quality. The voice detector may be incorporated into a cellphone, hands-free car phone, or any other device that provides voice output. The voice detector provides excellent voice output quality even when signal dropouts and other significant signal artifacts are present in the received signal. Not only does the high quality voice output improve the listening experience, it also benefits downstream processing systems that further process the voice signal.
