20090022350 | Acoustic Vibration Sensor - 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. | 01-22-2009 |
20090186668 | Wireless Handsfree Headset Method and System with Handsfree Applications - 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. | 07-23-2009 |
20100151788 | Headset and Audio Gateway System for Execution of Voice Input Driven Applications - A system including a headset and an audio gateway, and software applications that may be used with such headsets and gateways. The headset enables a user to discover and interact with applications resident on the headset, gateway, or a network accessible by the gateway. The headset functions as an application platform for the control and execution of the applications. The invention includes a method for providing a service to a user of the headset. The method involves the headset performing service discovery on the audio gateway to determine a method of transferring an application to the audio gateway, where the application provides the service. The headset causes the application to be transferred to the audio gateway using a method based on the service discovery, and the audio gateway executes the application, enabling the user to issue voice commands that are executed by the audio gateway to provide the service. | 06-17-2010 |

20140372113 | MICROPHONE AND VOICE ACTIVITY DETECTION (VAD) CONFIGURATIONS FOR USE WITH COMMUNICATION SYSTEMS - 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. | 12-18-2014 |
20150230021 | MULTI-MODAL AUDIO SYSTEM WITH AUTOMATIC USAGE MODE DETECTION AND CONFIGURATION CAPABILITY - An audio system that may be used in multiple modes or use scenarios, while still providing a user with a desirable level of audio quality and comfort. The inventive system may include multiple components or elements, with the components or elements capable of being used in different configurations depending upon the mode of use. The different configurations provide an optimized user audio experience for multiple modes of use without requiring a user to carry multiple devices or sacrifice the audio quality or features desired for a particular situation. The inventive audio system includes a use mode detection element that enables the system to detect the mode of use, and in response, to be automatically configured for optimal performance for a specific use scenario. This may include, for example, the use of one or more audio processing elements that perform signal processing on the audio signals to implement a variety of desired functions (e.g., noise reduction, echo cancellation, etc.). | 08-13-2015 |
