摘要:
A voice acquisition system for a vehicle includes a microphone having a first microphone element and a second microphone element. The system includes circuitry for processing signals output by the first and second microphone elements. The first microphone element is disposed at a first acoustic port and the second microphone element is disposed at a second acoustic port. The first acoustic port is at least partially isolated from the second acoustic port. When the microphone is normally mounted in an interior cabin of a vehicle, vocal signals emanating from an occupant of the vehicle pressurize the first microphone element at the first acoustic port ahead of pressurization by the vocal signals of the second microphone element at the second acoustic port. The voice acquisition system may include at least one of (i) discrimination of vocal signals from non-vocal signals, (ii) noise cancellation and (iii) filtering of noise.
