Patent ID: 7496387

Claim:
A system for wireless communications using speech recognition comprising: a device configured for processing speech signals using speech recognition circuitry, the device including at least some back end speech recognition processing circuitry; a headset with a microphone for capturing audio signals to be processed, the headset configured for performing front end speech recognition processing by initially forming sampled spectral transforms of the captured audio signals and processing the sampled spectral transforms of the captured audio signals using speech detection circuitry to determine that the captured audio signals include user speech as opposed to extraneous noise; the headset including switching circuitry that is operable to facilitate selectively wirelessly transmitting, to the device, the sampled spectral transforms of the captured audio signals when user speech rather than noise is detected from the spectral transforms and to not allow transmitting to the device when user speech is not detected; the back end speech recognition processing circuitry of the device using the spectral transforms transmitted by the headset to complete the speech recognition of the system.
