Voice processor supports far-field voice capture

June 13, 2017 // By Julien Happich
XMOS' XVF3000 family of voice processors provide far-field voice capture using arrays of MEMS microphones. With optional support for Sensory’s TrulyHandsfree technology, the industry’s leading voice-trigger solution, the XVF3000 family provides the most flexible and cost effective always-on voice interface in a single device, claims XMOS.

The company also announced a speaker development kit, the VocalFusion (XK‑VF3100‑C43) including an XVF3000 processor card and a 4-mic circular microphone array. The kit provides a quick way to start developing far-field voice capture applications.

XVF3000 devices include speech enhancement algorithms that include an adaptive beamformer, which uses signals from four microphones to track a talker on his move, coupled with high performance full-duplex, acoustic echo cancellation. XVF3000 devices can be easily integrated with an applications processor or host PC via either USB for data and control or a combination of I2S and I2C. Developers can quickly add custom voice and audio processing using the XMOS free development tools.

XVF3000 devices are available immediately from XMOS, and the VocalFusion speaker development kit will be available in July 2017.
