Voice capture eval. kit integrates into flat/linear product formats

December 01, 2017 // By Graham Prophet
XMOS (Bristol, UK) is extending its portfolio of far-field voice capture solutions with the xCORE VocalFusion Speaker Linear evaluation kit to address the application space it terms “edge-of-room”.

Based on the XMOS VocalFusion XVF3100 voice processor, the kit is designed for developers, OEMs and ODMs integrating voice user interfaces into flat, or linear consumer electronics typically found at the “edge of the room”, such as smart home control panels and washing machines.

 

A development of the VocalFusion 4-Mic for Amazon AVS launched in October 2017, it is intended to ensure that developers can easily integrate high performance voice interfaces, with an architecture that enables innovative and very flexible deployments.

 

As with all other XMOS far-field evaluation kits, voice commands are captured from across the room for processing by a cloud-based speech recognition system or local application processor, even in complex acoustic environments. The XVF3100 voice processor delivers sophisticated voice digital signal processing (DSP) 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 an adaptive beamformer that follows a speaker. Additional de-reverberation, automatic gain control, and noise suppression provide clear voice interaction experiences even in noisy environments.

 

With support for Sensory’s TrulyHandsfree keyword trigger technology, the XVF3100 claims the most flexible and cost effective always-on voice interface in a single device.

 

The VocalFusion Speaker Linear evaluation kit (XK-VF3100-L33) is immediately available to developers, OEMs, and ODMs from Digi-Key. For more information on this XMOS kit and XVF3100 devices visit www.xmos.com/vocalfusion. The evaluation kit uses Infineon MEMs microphones.
