Apparatus and method of improving the quality of recorded dictation in moving vehicles
First Claim
1. Dictation system mounted in a passenger compartment of a vehicle which is exposed to uncontrollable ambient or background noises, said system comprising recording means mounted within the passenger compartment of a motor vehicle for recording desired audio signals;
- a microphone associated with said recording means for converting desired audio to be recorded within said compartment into audio signals;
control means for actuating said recording means during dictation; and
ambient noise suppression means for substantially eliminating interference caused by the uncontrollable ambient or uncontrollable background noises during the recording process to thereby ensure that the resulting recording primarily includes only the desired audio and not the uncontrollable ambient or uncontrollable background noises.

Abstract
A dictation system is disclosed which includes circuitry for eliminating or substantially reducing the effect of uncontrollable ambient noise typically found in a passenger compartment of a moving vehicle. The system utilizes or incorporates, for example, the vehicle'"'"'s radio receiver and can be used to record local dictation or reception of audio from a remote location by means of a cellular telephone. One feature includes compression of speech during dictation to minimize transmission time from the vehicle to a remote base location for transcription.
