    摘要： A system estimates the spectral noise power density of an audio signal includes a spectral noise power density estimation unit, a correction term processor, and a combination processor. The spectral noise power density estimation unit may provide a first estimate of the spectral noise power density of the audio signal. The correction term processor may provide a time dependent correction term based, at least in part, on a spectral noise power density estimation error of the actual spectral noise power density. The correction term may be determined so that the spectral noise power density estimation error is reduced. The combination processor may combine the first estimate with the correction term to obtain a second estimate of the spectral noise power density that may be used for subsequent signal processing to enhance a desired signal component of the audio signal.

    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： 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.
