ANALYSIS OF SOUND PATTERNS THROUGH WAVELET TRANSFORMS
Richard Kronland-Martinet, J. Morlet, A. Großmann · International Journal of Pattern Recognition and Artificial Intelligence · 1987
This paper starts with a brief discussion of so-called wavelet transforms, i.e., decompositions of arbitrary signals into localized contributions labelled by a scale parameter. The main features of the method are first illustrated through simple mathematical examples. Then we present the first applications of the method to the recognition and visualisation of characteristic features of speech and of musical sounds.
