XMOS, Inc., a leading provider of advanced embedded voice and audio solutions for the consumer electronics market, has announced the release of its VocalFusion Stereo Development Kit for Amazon Alexa Voice Service (AVS), now certified by Amazon. This development kit offers a linear microphone array solution that delivers far-field performance along with stereo echo cancellation (AEC). As the market for Alexa-powered smart TVs, echo walls, set-top boxes, and digital media adapters continues to grow, true stereo AEC support becomes essential for delivering an immersive "all-room" voice interface experience. The new XMOS kit is specifically designed for developers targeting these emerging segments.
"This is XMOS’s second Amazon-certified development kit for Alexa voice services," said Mark Lippett, CEO of XMOS. "Last October, we launched our AVS kit, which was the first-to-market solution for linear microphone arrays. It generated significant interest from companies developing new products in this space. Positive customer feedback and encouragement from Amazon have driven us to quickly develop this stereo kit for the next generation of Alexa-enabled audio and video devices. It highlights the advantages and flexibility of our programmable XMOS technology."
"As Alexa moves beyond the desktop into room-edge devices, developers are seeking innovative ways to seamlessly integrate Alexa into home environments so it can respond anywhere in the room," said Abhom, Director of Alexa Voice Services at Amazon. "The new XMOS stereo far-field linear development kit for AVS provides the performance and thin form factor needed for these new devices. It opens up new opportunities for Alexa integration in stereo home entertainment systems and wall-mounted AV equipment."
**About the VocalFusion Stereo Development Kit for Amazon AVS**
At the heart of the kit is the XVF3500 voice processor, which delivers advanced voice digital signal processing, including dual-channel full-duplex acoustic echo cancellation (AEC). Like all other XMOS VocalFusion solutions, it ensures clear command capture from any part of the room, even in challenging noise environments, and seamlessly integrates with the Alexa voice service.
The processor connects directly to four PDM microphones arranged in a linear array with a spacing of 33.33mm, making it ideal for integration into flat panel displays and devices positioned at the "room edge." This makes the kit particularly well-suited for smart home and entertainment applications where compact design and high performance are key.
