    摘要: A voice processing system for a vehicle environment is provided for detecting a sound signal in the vehicle environment and identifying a voice command that originates from a vehicle user outside the vehicle. The voice processing system, in the detected the sound signal, takes into account position information relating to the position of the vehicle user in the vehicle environment. Information on the position of the vehicle user may be obtained from a keyless-go-system or another monitoring device of the motor vehicle, for example an optical imaging device of a parking-assistance system or a driver-assistance system.

    摘要: An audio processing system controls an audio input signal. The audio processing system includes a signal analyzer that detects content information and source information corresponding to the audio input signal. The system generates an analyzed audio signal. A signal processor receives the analyzed audio signal and generates a processed audio signal based on the content information and/or source information.

    摘要: An echo reduction system includes a signal analysis filter that converts an input into sub-band signals. A signal down-sampling circuit down-samples the sub-band signals at a first down-sampling rate. An echo analysis filter converts a loudspeaker signal into echo sub-band signal that are further processed by an echo down-sampling circuit. The circuit down-samples the echo sub-band signals at a second down-sampling rate to generate down-sampled echo sub-band signals. An echo compensation filter folds the down-sampled echo sub-band signals with an estimated impulse response of a loudspeaker-room-input system. A second echo down-sampling circuit down-samples the folded down-sampled echo sub-band signals at a third down-sampling rate to generate estimated echo sub-band signals. The first down-sampling rate is equal to the product of the second and third down-sampling rates.
