  VoCon®AEC is a powerful algorithm for achieving acoustic echo cancellation (AEC) and noise reduction in telephony applications hands-free car kits at vehicles of different sizes. Highly adaptive VoCon®AEC is platform independent and is easily portable (even to 16-bit signal processors). This product often deployed together with VoCon3200 speech recognition engine.
