XMOS announced the launch of its 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 voice-trigger technology, the XVF3000 family intends to provide manufacturers with the most flexible and cost effective always-on voice interface in a single device.
XMOS also announced the availability of its VocalFusion Speaker development kit (XK‑VF3100‑C43), 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.
“Today is a very significant day for XMOS. We’re introducing XVF3000 and VocalFusion Speaker as the first in a range of voice capture products. Based on our powerful and flexible xCORE microcontroller architecture, XVF voice processors open up new possibilities for designers looking to deliver high performance voice capture in a very cost-effective form factor,” says Mark Lippett, CEO at XMOS.
“We’re excited to be at the forefront of the revolution driven by products like Amazon Echo and Google Home, which have shown the possibilities for voice interfaces. We are working worldwide with customers and partners to accelerate the adoption of voice as the interface of choice for the Internet of Things.”
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.
XVF3000 devices are available immediately from XMOS, and the VocalFusion Speaker development kit will be available in July 2017. In the meantime, developers can register for early access to the company’s Beta program and download further information at: www.xmos.com/xcorevocalfusion.
