Recognition of environmental sounds

The author describes a preliminary study designed to answer the question, ´How well can familiar environmental sounds be identified?´ By familiar is meant sounds on which the recognition system has been previously trained. Environmental sounds are sounds generated by acoustic sources common in domestic, business, and out-of-doors environments. The results of this study indicate that well-isolated familiar sounds can be recognized with high accuracy by applying standard statistical classification procedures to feature vectors derived from two-dimensional cepstral coefficients.<>
