There are situations where hands free technology is indispensable (such as in a operating theatre) or just simply very useful (in offices or dental surgeries).

It allows a much more natural form of communication, as if the communication partner was right next to you.

Therefore it is easier to concentrate on the conversation, which is essential in critical situations.

The main acoustic issues are echo cancellation and noise suppression, although there are others as well.

Commend’s hands-free speech technology is a far cry from what is used in mobile or desktop phones. A speaking distance of up to 7 meters (21 feet) is a result of using the best possible quality microphones and loudspeakers combined with Commend’s own echo cancelling and noise reduction software.
