1. A system for automatic recognition of vehicular noises comprising:
- at least one microphone installed within a vehicle cabin, the microphone adapted to detect acoustic signals within the cabin and to generate corresponding microphone signals;
a database comprising speech templates and operating noise templates;
a feature extracting module configured to receive the microphone signals and to extract at least one of a set of operating noise feature parameters and a set of speech feature parameters from the microphone signals; and
a speech and noise recognition module configured to determine one of an operating noise template having operating noise feature parameters, and a speech template having speech feature parameters, that best matches either the extracted set of operating noise feature parameters or the extracted set of speech feature parameters.

Abstract
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.
