Title: Method for extracting feature from acoustic signal generated from one sound source and method for extracting feature from acoustic signal generated from a plurality of sound sources
Inventor: MICHAEL A KASEI
IPC: G10L19/00
Filed: 2002-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a computerized method for extracting features from acoustic signals generated from one or a plurality of sound sources. SOLUTION: The acoustic signal are first windowed and filtered to produce a spectral envelope for each source. The dimensionality of the spectral envelope is then reduced to produce a set of features for the acoustic signal. The features in the set are clustered to produce a group of features for each of the sources. The features in each group include spectral features and corresponding temporal features characterizing each source. Each group of features is a quantitative descriptor that is also associated with a qualitative descriptor. Hidden Markov models are trained with sets of known features and stored in a database. The database can then be indexed by sets of unknown features to select or recognize like acoustic signals.
