From doorbells to smart TVs, our devices are getting smarter. Voice-control is transforming the way in which we access and enjoy content. However, capturing a clear voice command from a distance isn’t easy. It requires some complex digital signal processing (or DSP). And that’s where XMOS comes in, with the VocalFusion® range of high performance voice interfaces.
