Voice processing evaluation board for linear microphone arrays

November 30, 2017 // By Peter Clarke
XMOS Ltd. (Bristol, England) is offering an evaluation kit for far field voice capture and voice processing using linear arrays of microphones.

The system is based on Infineon MEMS microphones and the XVF3100 voice processor from XMOS. It is designed for those that want to integrate voice user interfaces into consumer electronics typically found at the edge of the room, such as smart home control panels and washing machines.

Voice commands are captured from across the room using either a cloud-based speech recognition system or local application processor. The XVF3100 comes with keyword trigger technology from Sensory for an always-on voice interface.

The XVF3100 voice processor provides 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. Dereverberation, automatic gain control, and noise suppression help voice interaction in noisy environments.

The VocalFusion Speaker Linear evaluation kit (XK-VF3100-L33) is available to developers, OEMs, and ODMs from Digi-Key.

The evaluation kit uses Infineon MEMs microphones.
