Oral-Nasal Vowel Contrasts: New Perspectives on a Debated Question
نویسنده
چکیده
This study deals with data about the acoustic properties of nasal vowels of the Twi language, spoken in Ghana, compared to the oral counterparts. Evidence from our data shows a general tendency whereby F2 and F3 of the nasal vowels are lower than the oral counterparts in both the short and long contexts. Acoustic data also reveal that nasal-oral contrast depends on the vowel type. Nasal vowels have higher durational values than oral vowels in the short and long phonological categories.

Perception and representation of Bengali nasal vowels
The paper addresses the question of native speakers’ online awareness and perceptual use of phonetic nasalisation by examining surface nasalisation in two types of surface vowels in Bengali: underlying nasal vowels and nasalised vowels before a nasal consonant. In a cross-modal forced-choice experiment, we investigate the hypothesis that only unpredictable nasalisation is represented and that t...
متن کاملAcoustic Analysis of Persian EFL Learners' Pronunciation of English Vowels
This paper reports the results of an experimental study on non-native production of English vowels. Two groups of Persian EFL learners varying in language proficiency were tested on their ability to produce the nine plain vowels of American English. Vowel production accuracy was assessed by means of acoustic measurements. Ladefoged and Maddison’s (1996) F1 F2 measurements for American English v...
متن کاملRule Based Speech Synthesis by Cepstral Method for Standard Bangla
In the first phase of this paper, we describe the construction of a Bangla speech synthesizer. In the second phase, we discuss our work on Bangla nasal vowel. Nasality is one of the distinctive characteristic of Bangla phonemes. We discuss methods employed for transforming Bangla oral vowel to the corresponding nasal vowel counterpart and its application to our speech synthesizer. The perceptua...
متن کاملGestural coordination of Brazilian Portugese nasal vowels in CV syllables: A real-time MRI study
The coordination of velum and lingual gestures for Brazilian Portuguese nasal vowels in CV syllables is studied with real-time magnetic resonance imaging (rt-MRI). Four syllable structures were compared: stop-oral vowel, stop-nasal vowel, nasal-oral vowel, nasal-nasal vowel. Results show near-synchrony timing (in-phase) for the consonant onset and nasal vowel’s lingual onset, and for the conson...
متن کاملAcoustic correlates of phonological status and their effect on phonological processing
Recent work has shown that by 11 months, infants process sounds differently depending on whether they are in an allophonic relationship in the infants' ambient language (i.e., nasal and oral vowels in American English) or a phonemic one (i.e., nasal and oral vowels in Quebec French; Seidl et al., 2009). Previous experimental work suggests that adults' perceptual similarity and lexical access is...
