Abstract :
A voice processor is a dedicated audio signal-processing chip for mobile phones and personal computers that enables high-performance noise reduction and acoustic echo cancellation for highly noisy environments. The algorithms and hardware underlying these chips´ performance are based on the sophisticated operation of the human hearing system.
