Abstract: A system, apparatus, and method for generating a spatial user interface for an application, system or device. The user interface includes a means of representing user interface functions or commands as audio signals, with the audio signals being perceived by the user in a spatially different location depending on the function or command. A user input device is provided to enable a user to select a function or command, or to navigate through the spatial representations of the audio signals.

Abstract: 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.).

Abstract: 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.

Abstract: A new type of headset that employs adaptive noise suppression, multiple microphones, a voice activity detection (VAD) device, and unique mechanisms to position it correctly on either ear for use with phones, computers, and wired or wireless connections of any kind is described. In various embodiments, the headset employs combinations of new technologies and mechanisms to provide the user a unique communications experience.

Abstract: Voice Activity Detection (VAD) devices, systems and methods are described for use with signal processing systems to denoise acoustic signals. Components of a signal processing system and/or VAD system receive acoustic signals and voice activity signals. Control signals are automatically generated from data of the voice activity signals. Components of the signal processing system and/or VAD system 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.
