Essai d'analyse de la prosodie du Mooré : ton et intonation

Abstract : This dissertation describes the role of prosody in the organization of oral speech in Moore (a tone language spoken in Burkina Faso). It investigates the realization of intonation as a sign of prosodic structure in an African tone language. The main problem dealt in this study is: how does intonation work in moore, a tone language in which tone has already an important phonological role?The aim of the analysis is to explain the realization of tone and intonation in order to identify a prosodic structure which will account for the prosodic organization in moore. The theoretical framework is based on P. Martin’s theory of intonation in romance languages (2009, 2013, and 2015). Of course amendments were necessary to adapt it to moore.This dissertation is made up of two sections; the first one is dedicated to defining some important notions of the study and presenting general characteristics of moore. In the second section, experiments were carried out to address the main issues.The phonetic realization of tone was first examined. This study confirms that the relative height of the pitch is the main acoustic parameter used to distinguish the two types of tones in moore.Then the analysis of the relation between tone and intonation reveals that the realization of tones is affected by intonation especially at prosodic boundaries. When downstep is applied, tonal rules determine the realization of tones. However, the domain of the downstep is also marked out by prosodic boundaries (place of the realization of intonation).Finally, based on the identification of prosodic events, the study of moore oral speech (both spontaneous and reading speech) organization shows that acoustic parameters such as: duration of pauses, final syllable lengthening and F0 variations are found with perceived boundaries. The analysis of reading speech reveals that F0 resetting and variations of boundary syllables duration are the major indices which mark the limits of prosodic phrases. In spontaneous speech, the results suggest the existence of a trading relationship between pauses duration and boundary syllables duration. Therefore, the prosodic organization of utterances in moore derives from the combination of F0 variations and the trading relationship.
