XMOS Ltd announced that they will be showcasing their portfolio of far-field voice capture solutions for voice-enabled stereo smart TVs, soundbars, set-top boxes, and digital media adapter markets at GSMA Mobile World Congress 2018, Barcelona, 26^th February to 1^st March. Smart speakers with Alexa Voice Service and Google Assistant support have dramatically changed how consumers interact with entertainment systems, and the demand for voice controlled stereo audio and entertainment systems that appear at the edge of rooms is forecast to increase dramatically.

XMOS will be demonstrating their latest products, commercial solutions in development, and proof of concepts that capture voice commands accurately from across the room even when the audio appliances are playing content at high volume in complex noisy acoustic environments.

• VocalFusion Stereo Dev Kit (XK-VF3500-L33): The world’s first stereo acoustic echo cancellation (AEC) far-field linear microphone array solution, is based on the XVF3500 voice processor which delivers 2-channel full stereo-AEC. Uniquely, the solution also supports configurable AEC latency, where the AEC reference signals can be accurately calibrated, and the latency adjusted, to enable after-market far-field voice accessories for existing consumer electronics products.
• VocalSorcery: A Blind Source Signal Separation technology that can spatially identify individual speakers or conversations within a crowded noisy audio environment to achieve optimized voice capture and input into speech recognition systems. This technology could be used for example to diarize voice conferences, and give a full transcript, by speaker of multi-person conversations, and ensure that all speakers on a conference call are heard with equal volume.

“Our stereo development kit delivers state of the art acoustic echo cancellation, and is ideally suited for stereo TV, soundbar and set-top box applications” commented Mark Lippett, President and CEO at XMOS. “We’re delighted to bring this solution to GSMA Mobile World Congress where voice, AI and biometrics are enabling new forms of human-machine interface.”

“We’re also very proud to be able to demonstrate our next generation of source separation algorithms, VocalSorcery, which solves what is sometimes described as the “Cocktail Party Problem”, and enables commercial solutions for improved conference calls and in-car phone calls,” he added. “With our class-leading stereo solution, and our next generation of algorithms on show, we are confident that we have the most comprehensive portfolio of voice products available today.”

XMOS voice processors deliver sophisticated voice digital signal processing (DSP) including a full duplex acoustic echo canceller (AEC) with barge-in capability that enables users to interrupt or pause a device that’s playing music, and an adaptive beamformer that follows a speaker. Additional sophisticated dereverberation, automatic gain control, and noise suppression provide crystal clear voice interaction experiences even in noisy environments, in a single device.

XMOS will be in a Hall 7 Meeting Room (by appointment only) Mobile World Congress 2018, Barcelona, 26th February -1st March 2018. Visit this page to arrange a meeting with the XMOS team.
