XMOS Ltd (http://www.xmos.com) announces its VocalFusion 4-Mic Dev Kit for Amazon Alexa Voice Service (AVS) is the first far-field linear mic array solution available. The XMOS kit is ideal for developers who want to integrate Alexa into smart panels, kitchen appliances, and other commercial and industrial electronics.
The kit features a compact four-microphone linear 100mm array. The captured voice signals are crystal clear 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 the only solution to date that packs audio digital signal processing (DSP) and programmable I/O processing and control software into a single chip, enabling customers to significantly reduce their bill of materials, flexibly tailor their designs, and reduce costs.
The VocalFusion 4-Mic Dev Kit for Amazon AVS is the first development kit to feature a reference client built using the recently released AVS Device SDK. The AVS Device SDK is designed to further simplify the experience of creating Alexa-enabled products, thereby helping commercial device makers get AVS products to market faster.
At the heart of the XMOS solution is the VocalFusion XVF3000, a highly integrated far-field voice processor based on the XMOS award-winning xCORE multicore architecture. 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.
