Voice processor tech enables business conference calling

XMOS VocalFusion technology was chosen for its ability to detect and isolate the spoken word within 8m in all directions, thanks to far-field voice recognition capability and an array of seven eMeet 360° omni-directional microphones.

The XMOS XVF3000 voice processor uses acoustic echo cancellation (AEC) to remove playback audio from the microphone signal allowing users to barge-in and talk over the playback signal. Automated noise suppression (ANS) and dereverberation technologies are used to remove unwanted noise and echoes in the captured signal, providing a crystal clear output signal. The microphone follows a voice as it moves around the room (via beamforming), and ensures that even the quietest person in the room can be easily heard.

“We chose the XMOS VocalFusion technology for our eMeet OfficeCore M1 because of the superior far-field voice technology and unrivalled processing power it can deliver for thin client applications,” said Wyman Chen, CEO at eMeet. “Our product is aimed at the professional conference call market, so quality of voice capture, noise isolation and AEC were key to the design. We’re extremely pleased with the result and the benefits that the XMOS technology has delivered to our product.”

Commenting on the announcement, Mark Lippett, President and CEO at XMOS, said: “The eMeet solution is a typical example of the type of work our teams are involved in with professional and consumer electronics companies worldwide. Our technology is perfectly suited to addressing the issues of conference call quality in noisy environments, and eMeet has used this capability to deliver a superior product for business environments. We are seeing a huge demand for the benefits that our VocalFusion technology can deliver in an unprecedented range of applications and eMeet is one of the first companies to realise that potential in a commercial product.”
