    摘要： Improving the acoustical communication between interlocutors in at least two positions in a room includes generating electrical signals representative of acoustical signals present at the respective interlocutor positions, amplifying each of the electrical signals and converting the amplified electrical signals into acoustical signals. A time delay is applied to the electrical signals such that the acoustical signal arriving first at one of the interlocutor positions originates from the direction of the other interlocutor position.

    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 equalization system enhances the quality of communications between a remote party and a local party. The equalization system includes an equalization filter that equalizes an acoustic signal received from the remote party. The equalized acoustic signal is transmitted to a speaker based on the equalized acoustic signal. A device converts sound into electrical signals. The electrical signals are transmitted to an echo compensation filter that compensates for reflected sound. Filter characteristics of the equalization filter are based on filter characteristics of the echo compensation filter.

    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. The method further includes determining the position of the speaker on the basis of the microphone signals and automatically controlling the actuator of the element on the basis of the determined position of the speaker to adjust the element.

    摘要： A system automatically recognizes a vehicle operating condition through a microphone positioned within the vehicle. The microphone detects acoustic signals. A database stores speech templates and operating noise templates. A feature extracting module receives microphone signals and extracts a set of operating noise feature parameters or speech feature parameters from the microphone signals. A speech and noise recognition module may determine an operating noise template that best matches a set of extracted operating noise feature parameters and/or a speech template. The speech template best matches the set of extracted speech feature parameters.
