摘要： An adaptive signal processing system eliminates noise from input signals while retaining desired signal content, such as speech. The resulting low noise output signal delivers improved clarity and intelligibility. The low noise output signal also improves the performance of subsequent signal processing systems, including speech recognition systems. An adaptive beamformer in the signal processing system consistently updates beamforming signal weights in response to changing microphone signal conditions. The adaptive weights emphasize the contribution of high energy microphone signals to the beamformed output signal. In addition, adaptive noise cancellation logic removes residual noise from the beamformed output signal based on a noise estimate derived from the microphone input signals.

摘要： A system locates a speaker in a room containing a loudspeaker and a microphone array. The loudspeaker transmits a sound that is partly reflected by a speaker. The microphone array detects the reflected sound and converts the sound into a microphone signal. A processor determines the speaker's direction relative to the microphone array, the speaker's distance from the microphone array, or both, based on the characteristics of the microphone signals.

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： A system for automatic adjustment of at least one element provided with at least one actuator and provided inside or outside a vehicular cabin is provided. The system includes at least one microphone array for detecting utterances of at least one speaker and for obtaining microphone signals corresponding to the utterances. A localization detector is configured to determine the position of the speaker on the basis of the microphone signals. The localization detector outputs a localization signal to a controller. The controller is configured to receive the localization signal and automatically controls the actuator of the element on the basis of the localization signal. A method for automatically adjusting at least one element provided with at least one actuator and provided inside or outside a vehicular cabin is also provided. The method includes detecting utterances of a speaker by a microphone array and obtaining microphone signals corresponding to the utterances.

摘要： The present invention relates to a method with which speech is captured in a noisy environment with as high a speech quality as possible. To this end, a compact array of, for example, two single microphones is combined to form one system through signal processing methods consisting of adaptive beam formation and spectral subtraction. Through the combination with a spectral subtraction, the reference signal of the beam former is freed from speech signal components to the extent that a reference signal of the interference is formed and the beam former produces high gains.
