    摘要: A microphone compensation system responds to changes in the characteristics of individual microphones in an array of microphones. The microphone compensation system provides a communication system with consistent performance despite microphone aging, widely varying environmental conditions, and other factors that alter the characteristics of the microphones. Furthermore, lengthy, complex, and costly measurement and analysis phases for determining initial settings for filters in the communication system are eliminated.

    摘要: To reliably and consistently detect desirable sounds, a system detects the presence of wind noise based on the power levels of audio signals. A first transducer detects sound originating from a first direction and a second transducer detects sound originating from a second direction. The power levels of the sound are compared. When the power level of the sound received from the second transducer is less than the power level of the sound received from the first transducer by a predetermined value, wind noise may be present. A signal processor may generate an output from one or a combination of the audio signals, based on a wind noise detection.

    摘要: A feedback reduction system adaptively processes a microphone signal. An adaptive feedback suppression filter circuit processes the microphone signal, and an adaptive feedback compensation filter circuit further processes the microphone signal. The adaptive feedback suppression filter circuit processes the signal based upon output from the adaptive filter compensation filter circuit.

    摘要: A vehicle communication system detects the presence of a passenger wearable communication device. The system receives audio signals from multiple sources inside or outside of a vehicle. The system processes the signals before routing the signals to multiple destinations. The destinations may include wearable personal communication devices, front and/or rear speakers, and/or a remote mobile device.

    摘要: A speech processing device includes an automotive device that filters data that is sent and received across an in-vehicle bus. The device selectively acquires vehicle data related to a user settings or adjustments of an in-vehicle system. An interface acquires the selected vehicle data from one or more in-vehicle sensors in response to a user's articulation of a first code phrase. A memory stores the selected vehicle data with unique identifying data associated with a user. The unique identifying data establishes a connection between the selected vehicle data and the user when a second code phrase is articulated by the user. A data interface provides access to the selected vehicle data and relationship data retained in the memory and enables the processing of the data to customize the in-vehicle system. The data interface is responsive to a user's articulation of a third code phrase to process the selected vehicle data that enables the setting or adjustment of the in-vehicle system.

    摘要: A system used in a loudspeaker-room-microphone environment includes a microphone signal partitioner that divides a signal from a microphone into one or more divided portions. A reverberation energy estimator estimates reverberation energy in some of the divided portions of the microphone signal based on a loudspeaker signal. The estimated reverberation energy is processed to generate a dereverberated output signal.
