With the Quikscribe Recorder you may use voice activated recording by checking the System Setting to enable voice activated recording.  Recording will occur only when you speak, and you may select the ambient sound level to trigger the recording over the background noise in the room.  The Quikscribe Recorder can also utilize a foot pedal to control recording functions for completely hands free recording.  Just tap the foot pedal buttons to create a new file, start/pause recording, then send the file to the transcriptionist.  More information is available at http://www.digidictate.com or http://www.digitaldictation.us
