VOCALFUSION DEV KIT

VOCALFUSION

USER GUIDE

Welcome to the VocalFusion Dev Kit for evaluation of the XMOS XVF3510 far-field voice processor. The XVF3510

voice processor interfaces to a 2-mic array, and uses the XMOS voice algorithms to capture commands several

metres away from the device and deliver a voice stream optimised for an Automatic Speech Recognition (ASR)

engine running on the system application processor. The algorithms include Acoustic Echo Cancellation and an

Interference Canceller for static point noise sources, making the XVF3510 the ideal solution for smart TVs, set-top

boxes and TV accessories that output multi-channel audio.
