XMOS: voice processor for integrated far-field voice capture and development kit
XMOS announces the launch of the XVF3000 family of voice processors, which provide class-leading far-field voice capture using arrays of MEMS microphones. With optional support for Sensory’s TrulyHandsfree technology, the XVF3000 family provides the most flexible and cost effective always-on voice interface in a single device. XMOS also announces the availability of the VocalFusion Speaker development kit, which includes an XVF3000 processor card and a 4-mic circular microphone array. This 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 as they 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.
