Upgrading legacy set-top boxes to far-field voice control with the XVF3510 voice processor

When it comes to controlling a set-top box (STB) by voice, user experience is critical. It needs to feel easy and intuitive; activated at any time, from anywhere in the room. A reliable voice interface should isolate the voice of interest and cancel out all unwanted or competing noise. Crucially, it also needs to be easy to implement – enabling manufacturers to meet their demanding time-to-market timescales.

That’s where the XMOS VocalFusion^® 2-mic voice processor (XVF3510) comes in.

This guide outlines the advantages of XVF3510 and how easily it can be deployed as a single chip solution for USB smart-microphone accessories, enabling upgrades to existing set-top boxes with far-field voice control.
