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.”


As with all other XMOS voice solutions, commands are accurately captured from across the room for processing by a cloud-based speech recognition system, even in complex acoustic environments. The XVF3500 voice processor delivers 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.

During CES 2018, XMOS will showcase their latest stereo-AEC system, the existing VocalFusion 4-Mic kit for Amazon AVS, VocalFusion speaker with linear and circular arrays, far-field voice processing commercial deployments, and human machine interface developments.
