Smart Home Applications Enabled by New XMOS Voice Capture Technology

March 22 2016, 03:10

XMOS announced the launch of its xCORE Array Microphone aggregation solution for voice user interfaces (VUI) in smart home applications. With the ability to aggregate up to 32 MEMS microphones, and offering USB and I2S backhaul, XMOS enables a new class of array microphones to be created. Applications include smart TVs, soundbars, virtual digital assistants (VDAs) and smart home automation.

Voice user interfaces (VUIs) are emerging as an approach to interacting with the growing number of smart devices found in our homes. Accurate, far-field voice capture underpins VUI technology and is best achieved using multiple microphones. Many of today’s solutions are limited to just two or four microphones whereas the XMOS solution can be deployed with up to 32, enabling improved user experiences through higher signal-to-noise performance and enhanced control of both sensitivity and directivity.

Commenting on the launch, Paul Neil, VP of Marketing at XMOS says, “Our microphone aggregation solution delivers new levels of performance and flexibility to smart home devices requiring far-field voice capture and speech recognition. Our ability to interface directly with digital MEMS microphones, combined with the integration of control and DSP functions in a single device enables our customers to create highly differentiated products, while reducing their total system bill of materials.” 
Rokid developed a new home assistant device and entertainment center using Artificial Intelligence and combining voice interaction with a clever lighting interface.

The new XMOS microphone array aggregator was already deployed by voice digital assistant pioneer Rokid (, a well-funded home-automation startup with offices in San Francisco, California, and Hangzhou and Beijing, China. “At Rokid, we are integrating the very latest technologies with a unique design aesthetic to create a new type of Artificial Intelligence for the home. We selected XMOS because of the flexibility of their solution, their ability to aggregate a large number of microphones and the maturity of their backhaul capabilities. With this product, XMOS is well positioned to lead the next generation of voice capture solutions”, commented Dan Wong, CEO at Rokid.
