Discriminant analysis of nasal vs. oral vowels in French: comparison between different parametric representations
نویسندگان
چکیده
The purpose of this paper is to investigate the realization of the [nasal] contrast in French by performing an acoustic analysis of naturally spoken nasal and oral vowels, and by carrying out discriminant analysis on these data. Results consistently show that generic parametric representations allow to reliably discriminate between nasals and orals. A specific issue addressed in this paper is the relationship between phonetic and phonological nasalization in French.

Coarticulation and contrast: Neighborhood density conditioned phonetic variation in French
Phonological neighborhood density (ND) conditions variation in a number of acoustic phonetic properties of words. For example, previous research has shown greater hyperarticulation and greater nasal coarticulation in high-ND English words than in low-ND words. Here, we investigate the effects of ND on vowel hyperarticulation and vowel nasality (coarticulatory and contrastive) in French. Acousti...

This paper provides a comparative gestural account of nasal vowels in Southern French (Marseille, Toulouse; France) and in Northern French (Liège, Tournai; Belgium). Timing measurements based on acoustic data confirm a different temporal organisation of the gestures between the two regiolects. We also report on statistical comparisons between phonetic events (such as duration of the SF ‘nasal a...

متن کاملSchlieren Study of External Airflow during the Production of Nasal and Oral Vowels in French
Schlieren imaging enables real-time visualization of airflow through refraction of light. The potential of schlieren imaging for speech research was first proposed nearly 40 years ago [1]. A recent study tested this proposal [2]. Phonetically trained raters coded schlieren recordings of French vowels as oral versus nasal [2] (Figure 1). Although raters discriminated between the oral and nasal v...
متن کاملVelar Movements for Two French Speakers
This study compares velar movements for nasal vowels and consonants; it investigates contextual nasalisation; and it provides new data on how nasalisation is affected by speech rate. Velar position is measured with an electromagnetic articulatograph (EMA) for two French speakers. Our results confirm that (i) nasal vowels are produced with a lower velum height than nasal consonants; (ii) the con...
