XMOS high-performance digital signal processing solutions help you build voice interaction service quickly into your products. Our stereo-AEC voice processor gives you up-close voice capture quality and processing accuracy at far-field range – even in noisy environments. Ideal if you want to integrate your speech recognition service into a smart TV, soundbar, set-top box or digital media adaptor.
Accurate voice capture and barge-in from across the room even when music is playing loudly and the commands are spoken softly.
Full duplex stereo-AEC, noise suppression and dereverberation. Cuts out noise and echo for optimised ASR processing.
With beamforming to track the voice of interest, you’ll get best in class performance at all angles and over long distances.
