XMOS launches its first voice processors

XMOS in Bristol has launched a family of voice processors to provide far-field voice capture using arrays of MEMS microphones. The move marks a shift away from general purpose microcontrollers and AVB Ethernet controllers and into the market for voice controlled equipment such as Amazon’s Echo and Apple’s home speaker.

The XVF3000 has optional support for Sensory’s TrulyHandsfree technology, the industry’s leading voice-trigger solution and the Xcore architecture provides a flexible and cost effective always-on voice interface in a single device.

XMOS also announces the availability of a development kit (the 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 [development kit] 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,” said 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.”

The 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. The controllers 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. Developers can register for early access to the Beta program and download further information at: www.xmos.com/xcorevocalfusion.
