Stereo-AEC linear far-field voice kit for smart devices

December 05, 2017 // By Jean-Pierre Joosting
XMOS has announced the XVF3500 voice processor, which supports stereo-AEC, along with the first stereo AEC far-field linear microphone array, the VocalFusion stereo evaluation kit (XK-VF3500-L33).

The XVF3500 voice processor delivers 2-channel full duplex acoustic echo cancellation (AEC). It is designed for developers working in the growing voice-enabled smart TV, soundbar, set-top box, and digital media adapter markets, all of which require stereo-AEC support for "across the room" voice-interface solutions.

Uniquely, the voice processor 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.

Commenting on the announcement, Mark Lippett, President and CEO at XMOS said, "This device and evaluation kit will fuel further growth in the integration of embedded voice controlled devices at the edges of our rooms, particularly those used for high quality music and TV control."
