Algorithmic Classification of Pitch Movements

Institute for Perception Research/IPO, Eindhoven, The Netherlands

In this paper, we discuss the construction of an algorithm that classifies pitch movements according to the IPO intonation labelling. The classification is performed by a feed-forward network, interpreted as a multi-linear classifier. In speaker-independent tests on a corpus of speech read by non-professionals, up to 81 % of the 279 pitch movements in the test corpus were correctly classified. These results are obtained by using information from the sampled speech data files only; a grammar will be used in the second stage of this study. Keywords: Automatic classification, multi-linear classification, IPO-intonation system, speech recognition.
