Resumen de Labeling Melodic Movements at the Stress Group Level

Lourdes Aguilar , David Casacuberta Sevilla , Rafael Marín Gálvez

• The aim of this work is to propose a system of F0 labeling using the stress group as the prosodic unit that can accurately relate linguistic and acoustic information. To obtain data, a corpus of sentences is given to read to a male speaker and the melodic information contained in the vowels is analyzed. The basic melodic movements -encoded as rise, fall and connection elements- between stress groups in an intonation group are observed in order to develop a set of rules assigning them from text. Results show that by means of the stress group it is possible to model some prosodic facts, such as the effect of sentence length on the height of the first F0 peak in the sentence, as well as to incorporate the syntactic information encoded in the lexical labeling of the stress group.
