XMOS Ltd 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.”
“As Alexa expands beyond table-top experiences and into edge-of-room devices, developers are looking for new ways to integrate Alexa seamlessly into the home environment where she can respond from anywhere in the room,” said Priya Abani, Director, Alexa Voice Service at Amazon. “This new stereo far-field linear development kit for AVS from XMOS provides the thin-form factor and high performance needed for these new device types. It opens up fresh opportunities to add Alexa in new ways to stereo home entertainment and wall-mounted AV equipment.”
The VocalFusion Stereo Kit for Amazon AVS (XK-VF3500-L33-AVS) is available to developers, OEMs, and ODMs from Digi-Key.
About VocalFusion Stereo Dev Kit for Amazon AVS
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). As with all other XMOS VocalFusion voice solutions, commands are accurately captured from across the room for processing by the Alexa Voice Service, even in complex, noisy acoustic environments.
The processor interfaces directly to four PDM microphones in a linear array with 33.33mm inter-mic spacing making it ideal for integration into flat screens and products found ‘at the edge of the room’.
