Silicon for Voice

VocalFusion XVF3510 voice processor

Part Number: XVF3510-QF60
Downloads: software and documents

The VocalFusion XVF3510 enables far-field voice capture with close range precision. It’s a turnkey solution for developers who want to embed far-field voice control into smart TVs and set-top boxes. Requiring just 2-microphones, the XVF3510 delivers compelling performance in a BOM-efficient package.

XMOS Acoustic Echo Cancellation, Interference Cancellation, Noise Suppression and Adaptive Delay Estimator algorithms are purpose designed to deliver accurate voice capture from across the room, even in noisy environments, and when content is streaming through the device.
