Dans ce travail nous explorons différentes causes de la variation phonétique. L'analyse d'un corpus multilingue de plusieurs types de parole nous permet d'observer une distinctivité variable des voyelles de chaque système en fonction du contexte de production. Cette variabilité peut être attribuée 1/ à la spécificité des systèmes vocalique, 2/ à la quantité d'information véhiculée dans le message linguistique.

This study is a cross-linguistic investigation of qualitative and quantitative variations due to 1/ the structure of vocalic system, 2/ the amount of context within speech message. We hypothesize that phonetic distinctivity of vowels in a language is relative to 1/ the properties of the phonological system, 2/ the amount of informational context. Three languages (Spanish, French and English) were analyzed in three different types of speech (isolated vowels, within words and within texts). Results show 1/ centralization in the three vocalic systems relative to the amount of context, 2/ an increase of vowel dispersion also due to an increase of context information.

The great amount of variation in speech production is an heterogeneous phenomenon which can be explained by many different factors. One of them could be the way phonological systems are structured. Thus strucural variations may be determined by the characteristics of each phonological system (number de phonemes, architecture of features in the system, prosodic structure, syllabic structure, phonotactics, phoneme frequencies, etc). The objective of the present paper is to understand whether the density of a vowel system, in other words the large or small number of vowels in the language, plays a significant role in vowel production. One hypothesis could be that speakers adapt their productions as a function of the number of vowels in their system, to occupy the entire space. A study performed by Manuel and Krakow (1984) showed that the tolerance for variation in the production of a vowel is lesser in a language with a filled vocalic system. On the contrary, Maddieson & Wright (1991) observed very few variation in a low density system (three vowels).
We plan to compare the production of vowels by French, Spanish and English speakers. In English, there are between 13 and 15 oral vowels while French distinguishes some 10 or 12. The density of these two systems is therefore similar, but the specific vowels in each differ considerably. In contrast, Spanish has a relatively sparse inventory, with only 5 vowels, but within this inventory we find the same vowels as in French and English (/a/, /e/, /i/, /o/ and /u/). These three languages thus offer the opportunity to distinguish the effects of density, without a concomitant difference in the phonological nature of the vowels present in the two systems (French and Spanish), from the effect of differing inventories of vowels within comparably dense systems (French and English).
In a previous study (Meunier, 2003), we observed that Spanish speakers produced smaller category areas than English ones. For Spanish speakers, there was basically no overlap between vowels as their number is lesser within the same global space : the density of the vowel system does not appear to have an impact upon the production of vowels. This observation goes against the hypothesis which predicted a larger production area for systems with fewer vowels. Nevertheless, this study was based on the analysis of isolated vowels: the controlled nature of the situation should have reduced variation.
In the present study, we compared vowels (Spanish, English and French) in three different contexts: isolated, in monosyllabic words, in two short texts. This corpus allowed us to evaluate the variability of vowel production according to the degree of control in speech production. First results show that, English vowel variation does not increase in less controlled situation (word and text) while Spanish and French vowel variation increased in text context. These results suggest that, in lesser controlled speech, the entire space of vocalic system is occupied whatever the density is. Density may be one of the parameters which can play a role on vowel variation. We hypothesize that vowel variation could be due to several properties of the phonological systems.

L'objectif de ce papier est de comprendre si la "densité" du système vocalique d'une langue, en d'autres termes, le nombre de voyelles dans la langue, joue un rôle dans la perception vocalique. Les résultats d'une expérience d'identification dans trois langues (français, anglais et espagnol) tendent à montrer que les sujets espagnols sont capables, sans hésitation, de catégoriser des stimuli absents de leur espace de production. En revanche, les résultats des sujets anglais montrent une très grande difficulté dans la tâche de catégorisation. Les résultats des sujets français sont intermédiaires. Nous concluons qu'un nombre peu élevé de voyelles dans le système vocalique facilite la tâche de catégorisation des sujets. De plus, le système anglais semble être plus complexe en ce qui concerne le type d'indices nécessaires pour identification des voyelles.

The objective of the present paper is to understand whether the "density" of the vowel system of a language, in other words the large or small number of vowels in the language, plays a significant role in the production and perception of vowels. Three languages (French, English and Spanish) are analysed. This work rests upon the comparison between speech production and the cognitive processing of linguistic units. Two different methodologies were employed in this aim : observation of phonetic productions and analyses of behavioural measures. First results lead us to hypothese that perception units can be larger than production units. In other words, the density of a vowel system seems to influence vowel perception but not vowel production.
