  • Apparatus and method for coordinating use of different microphones in a communication device
    Patent number: 9648419
    Abstract: A communication device is configured to receive signals using at least one acoustic microphone and at least one structural microphone. The communication device calculates one of first a signal-to-noise (SNR) ratio and a speech-to-noise ratio for the at least one acoustic microphone from received signals and calculates a SNR for the at least one structural microphone from received signals. The communication device compares one of the first SNR and the speech-to-noise ratio for the at least one acoustic microphone with the SNR for the at least one structural microphone. The communication device selects one of the at least one acoustic microphone and at least one structural microphone to receive speech responsive to the comparing and places a selected one of the at least one acoustic microphone and at least one structural microphone in a standby mode.
