Automatic recognition of vehicle operation noises

摘要

The present invention relates to a system for automatic recognition of operation noises of a vehicle, comprising at least one microphone installed in a vehicular cabin for detecting acoustic signals and generating microphone signals, a database comprising speech templates and operation noise templates, feature extracting means configured to receive the generated microphone signals and to extract at least one set of noise feature parameters and/or at least one set of speech feature parameters from the generated microphone signals, a speech and noise recognition means configured to determine at least one operation noise template that best matches the at least one extracted set of noise feature parameters and/or to determine at least one speech template that best matches the at least one extracted set of speech feature parameters and a control means configured to control the speech and noise recognition means to determine at least one operation noise template that best matches the at least one extracted set of noise feature parameters and/or to determine at least one speech template that best matches the at least one extracted set of speech feature parameters. The invention also relates to a method for recognizing operation noises of a vehicle comprising providing a speech recognition system comprising a database comprising speech templates and operation noise templates, extracting at least one set of noise feature parameters and/or at least one set of speech feature parameters from microphone signals generated from acoustic signals and determining at least one operation noise template that best matches the at least one extracted set of noise feature parameters and/or determining at least one speech template that best matches the at least one extracted set of speech feature parameters.
