Abstract

__________________________________________________________________________________________________________ Utilization of the piezoelectric accelerometer for the study of nasality in French as a Foreign Language The aim of this paper is to compare the production of French nasal vowels pronounced by 5 French native speakers and 5 Bosnian learners of French. In Bosnian, phonological nasal vowels do not occur. To record our data, we used a piezoelectric accelerometer which captured nasal vibrations from the lateral bone of the nose. We wanted to see the contribution of this instrument to the analysis of nasality for didactic purposes. The acoustic data show that the length difference between [a, ɛ, o] and [ɑ̃, ɛ̃, ɔ̃] is maintained in both languages by all speakers. Nasal vowels are longer then oral vowels. This difference is bigger in Bosnian than in French. Furthermore, our quantitative data from the mean percentage of RMS don’t show significant difference between Bosnian and French speakers: (1) when it’s about oral/nasal distinction and (2) difference between 3 nasal vowels. Piezoelectric accelerometer could provide interesting indications in a classroom. MOTS-CLES : accéléromètre piézoélectrique, nasalité, RMS, vibration nasale, FLE (Français Langue Etrangère), voyelle nasale, pourcentage de nasalité KEYWORDS : piezoelectric accelerometer, nasality, Root Mean Square (RMS), nasal vibration, French as a Foreign Language, nasal vowel, percentage of nasality 689 1

Le bosniaque ne possède pas de voyelles nasales. Les enregistrements ont été réalisés avec un accéléromètre piézoélectrique capturant les vibrations nasales au niveau de l’os latéral du nez. Nous voulons connaitre l’apport de cet instrument pour les analyses de nasalité en didactique du FLE. Les résultats acoustiques montrent que [ɑ̃, ɛ̃, ɔ̃], sont plus longues que [a, ɛ, o] chez tous les locuteurs et plus particulièrement chez les locutrices bosniaques. Les données quantitatives à partir du signal RMS (Root Mean Square) de l’accéléromètre piezoélectrique ne montrent pas de différences notoires entre les deux populations en ce qui concerne : (1) la distinction oral/nasal et (2) les différences entre les 3 voyelles nasales. L’accéléromètre piézoélectrique pourrait apporter des indications intéressantes en classe de langue.

Le bosniaque, avec cinq voyelles orales ([i, e, a, o, u]), possède un système vocalique moins riche que celui du …
