Amazon Alexa Voice Service dev kit allows far-field voice capture
The XMOS kit is aimed at developers who want to integrate Alexa into smart panels, kitchen appliances, and other commercial and industrial electronics.
It features a compact four-microphone linear 100mm array able to capture crystal clear voice signals even in noisy environments, enabling commands to be accurately captured from across the room for processing by the Alexa cloud-based speech recognition system. XMOS is believed to be the only solution to date that packs audio digital signal processing (DSP) and programmable I/O processing and control software into a single chip. The VocalFusion 4-Mic Dev Kit features a reference client built using the recently released AVS Device SDK. The XVF3000 delivers sophisticated voice DSP capability including a full duplex acoustic echo canceller (AEC) with barge-in capability that enables users to interrupt or pause a device that’s playing music, and sophisticated noise suppression with adaptive beamforming to provide high quality voice interaction experiences even in noisy environments.
