VocalFusion mono-AEC development kits

XMOS high-performance digital signal processing solutions help you build voice interaction services quickly into your products. Our mono-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 voice into kitchen appliances and smart panels for lighting, heating and security products.

  • Distance

    Distance

    Accurate voice capture and barge-in from across the room even when music is playing loudly and the commands are spoken softly.

  • Clarity

    Clarity

    Full duplex mono-AEC, noise suppression and dereverberation. Cuts out noise and echo for optimised ASR processing.

  • Direction

    Direction

    With beamforming to track the voice of interest, you’ll get best in class performance at all angles and over long distances.
