XMOS VocalFusion Stereo Development Kit

A linear reference solution with stereo AEC for AVS

XMOS VocalFusion Stereo
Development Kit for Amazon AVS

Price $499.00

The XMOS VocalFusion Stereo Development Kit for Amazon AVS is designed for developers who want to evaluate and prototype the Alexa Voice Service for slim profile or wall-mounted devices requiring stereo echo cancellation. Those devices include smart TVs, sound bars, set-top boxes, and digital media adapters.

The development kit features a four-microphone linear array for far-field voice capture. Built around XMOS' XVF3500 voice processor, the development kit provides full-duplex stereo Acoustic Echo Cancellation (AEC) capability for improved barge-in performance. Adaptive beamforming and noise suppression optimizes voice recognition accuracy in noisy environments and from long distances.

Features include:

  • A reference client for Raspberry Pi 3 built using the AVS Device SDK
  • True stereo Acoustic Echo Cancellation
  • 100mm linear 4 microphone array with MEMS mics
