XVF3510 VocalFusion® Development Kit for Amazon AVS

XMOS’ development kit has an automatic delay estimator which adjusts audio reference signal latency dynamically

Image of XMOS XVF3510 VocalFusion Development Kit for Amazon AVS XMOS' XK-VF3510-L71-AVS development kit for Amazon Alexa voice service (AVS) has a two-mic turnkey solution with far-field voice capture and close-range precision. The interference canceller nulls point-noise to cancel out typical noise in the soundscape. Stereo acoustic echo cancellation suppresses unwanted speaker echo and enables barge-in across audio playing from the device while noise suppression removes background noise from other devices. The automatic delay estimator adjusts audio reference signal latency dynamically, ensuring the acoustic echo cancellation algorithms deliver a smooth, real-time barge-in experience.

Please note: this kit requires Raspberry Pi 3 to run AVS SDK and sensory TrulyHandsFree wake-word engine, plus an Alexa developer account.
