Abstract
Vocal and vocal-like sounds can be characterised and/or identified by using an intelligent classifying method adapted to determine prosodic attributes of the sounds and base a classificatory scheme upon composite functions of these attributes, the composite functions defining a discrimination space. The sounds are segmented before prosodic analysis on a segment by segment basis. The prosodic analysis of the sounds involves pitch analysis, intensity analysis, formant analysis and timing analysis. This method can be implemented in systems including language-identification and singing-style-identification systems.
