Claim One:
1. A sound classification system capable of adding and correcting a sound type, comprising: a sound receiver for receiving a sound signal to be recognized; a feature extractor for finding out a feature of said sound signal; a first database for storing statistical values of features of a plurality of sounds; a classifier for classifying said sound signal; a classification recorder for storing the classification result from said classifier and the feature of said sound signal; a second database for making a backup copy of data stored in said first database; a feature database for storing features of a plurality of sample sounds; an add/correct command processor, upon receipt of a command to correct a classification result or to add a new type, instructing said classification recorder to output the feature of the sound requiring correction or to be added; a type adding/correcting device for receiving the feature of the sound requiring correction or to be added outputted by said add/correct command processor, and updating the corresponding statistical values of the features in said first database; a precision calculator for calculating a ratio of accurate classification of the features of the sample sounds in said feature database by said classifier; and an image capturing device capable of capturing an image of an environment where the sound signal to be recognized is generated.
