xCORE-VOICE Processors | XMOS
VocalFusion voice processors maximise the multichannel audio capabilities of xCORE devices, high quality integrated DSP and flexible I/O, to deliver high quality far-field voice capture solutions in a single device. With interfaces defined in software, XMOS provides the most flexible high quality solution for designers and fastest time-to-market.
Based on arrays of digital MEMS microphone arrays, captured streams can be backhauled over USB or I2S interfaces to application processors, DSPs and PCs, or sent over a secure wireless connection to cloud speech recognition services.
VocalFusion solutions provide affordable voice interfaces for many product categories including: smart speakers and TVs, gaming consoles, IoT home hubs and home appliances.
VocalFusion Voice Processors
