摘要： A calibration device automatically calibrates a telephone hands free system. The device includes a signal processor that processes a received telephone signal that may be converted into audible sound through the hands free system. A first telephone and a second telephone communicate with the signal processor. The first telephone is programmed to transmit a predetermined test signal to the second telephone through a wireless or physical medium. A comparator compares the received test signal to a predetermined reference signal at a hands free interface. The comparison determines a deviation from the reference signal. An adaptor modifies the processing of the digitized aural information based on the deviation.

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. An interface acquires the selected vehicle data from 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 the user and establishes a connection between the selected vehicle data and the user when a second code phrase is articulated. A data interface provides access to the selected vehicle data and stored relationship data and enables the processing of the data to customize the in-vehicle system. The data interface is responsive to the 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 communication system enhances communications in a noisy environment. Multiple input arrays convert a voiced or unvoiced signal into an analog signal. A converter receives the analog signal and generates digital signals. A digital signal processor determines temporal and spatial information from the digital signals. The processed signals are then converted to audible sound.

摘要： A system and method for compensating audio signal components is disclosed. The method includes detecting, by a microphone, a sound signal. The sound signal comprises audio signal components resulting from reproducing an audio signal of an audio source and speech signal components corresponding to a speech signal from a person. The sound signal is filtered to whiten the sound signal. The audio signal components in the whitened sound signal are then compensated. The whitening of the compensated sound signal is removed. The filtering of the audio signal is performed using at least two filters in an alternating way, each filter using time-dependent filter coefficients.

摘要： An audio enhancement refines a short-time spectrum. The refinement may reduce overlap between audio sub-bands. The sub-bands are transformed into sub-band short-time spectra. A portion of the spectra are time-delayed. The sub-band short-time spectrum and the time-delayed portion are filtered to obtain a refined sub-band short-time spectrum. The refined spectrum improves audio processing.

摘要： A dereverberation and feedback compensation system reduces the echo received by a first audio device while reducing the speech feedback received from a second audio device. A decorrelation logic decorrelates audio signals from the first audio device. A first processor generates a noise compensation signal based on the decorrelated audio signals and system determined filter coefficients. The second processor generates an enhanced noise correlation signal based on speech signals of a second audio device and the filter coefficients used by the first processor.

摘要： An echo compensation system may remove undesirable audio signals. The echo compensation system may utilize adaptive filters to remove echoes and undesirable signals received by a microphone. The echo compensation system may inhibit adaptation of an adaptive filter when left and right channel audio signals are highly correlated. In a two-channel system, inhibiting adaptation of one of two adaptive filters may reduce computational power requirements, while still removing undesirable signals. In a four-channel system, inhibiting adaptation of all but one of the four adaptive filters may reduce computational power requirements by a greater percentage.
