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 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.

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.
