Embodiments include method for providing a handsfree service to a user of a wireless, handsfree headset. In an embodiment the method comprises the headset performing service discovery on the audio gateway to determine a method of transferring an application to the audio gateway, wherein the application provides the service, the headset causing the application to be transferred to the audio gateway using a method based on the service discovery; and the audio gateway executing the application, wherein this user issues voice commands that are executed by the audio gateway to provide the service.

Wireless handsfree headset method and system with handsfree applications

Communication systems are described, including both portable handset and headset devices, which use a number of microphone configurations to receive acoustic signals of an environment. The microphone configurations include, for example, a two-microphone array including two unidirectional microphones, and a two-microphone array including one unidirectional microphone and one omnidirectional microphone. The communication systems also include Voice Activity Detection (VAD) devices to provide information of human voicing activity. Components of the communications systems receive the acoustic signals and voice activity signals and, in response, automatically generate control signals from data of the voice activity signals. Components of the communication systems use the control signals to automatically select a denoising method appropriate to data of frequency subbands of the acoustic signals. The selected denoising method is applied to the acoustic signals to generate denoised acoustic signals when the acoustic signal includes speech and noise.

Microphone and voice activity detection (VAD) configurations for use with communication systems

An acoustic vibration sensor, also referred to as a speech sensing device, is provided. The acoustic vibration sensor receives speech signals of a human talker and, in response, generates electrical signals representative of human speech. The acoustic vibration sensor includes at least one diaphragm positioned adjacent to a front port and at least one coupler. The coupler couples a first set of signals to the diaphragm while isolating the diaphragm from the second set of signals. The coupler includes at least one material with acoustic impedance matched to the acoustic impedance of human skin.
