XMOS has announced its VocalFusion Stereo Dev Kit for Amazon AVS, the first linear mic array solution qualified by Amazon for far-field performance that supports stereo acoustic echo cancellation.
This XMOS development kit is designed for developers working in the growing Alexa-enabled smart TV, soundbar, set-top box, and digital media adapter market segments, all of which require true stereo-AEC support to deliver compelling “across the room” voice-interface solutions.
“This is the second XMOS kit for the Alexa Voice Service that is qualified by Amazon,” said Mark Lippett, President and CEO at XMOS commenting on the announcement. “The kit for AVS we launched in October last year was another ‘first to market’ that we delivered for developers, generating significant interest from companies working on new linear form factors. That positive customer feedback and encouragement from Amazon has driven us to rapidly develop this stereo kit for new Alexa-enabled audio and visual equipment, and demonstrates the benefits and agility of our programmable XMOS technology.”
The kit is based on the XVF3500 voice processor, which delivers sophisticated voice digital signal processing that includes 2-channel full duplex acoustic echo cancellation (AEC).
The processor interfaces directly to four PDM microphones in a linear array with 33.33mm inter-mic spacing making it suitable for integration into flat screens and products found “at the edge of the room”.
