This paper presents an analysis of acoustic duration of vowels in Djambarrpuyŋu, a Yolŋu Matha language spoken in Arnhem Land, in northern Australia. Djambarrpuyŋu has been described as having phonologically long and short vowels, and there have also been suggestions that consonants following short vowels undergo compensatory lengthening. The aims of this study are to investigate the phonetic n...

This paper deals with pitch estimation of spoken Devnagari vowels from the original speech signals. Devnagari vowels are playing the vital role in pronunciation of any word. Each vowel is classified as starting, middle and end according to the duration of occurrences in the word. The Devnagari script having 12-vowels and 34-consonants are used in some Indian language like Marathi. The Devnagari...

We studied mutual influences between native and non-native vowel production during learning, i.e., before and after short-term visual articulatory feedback training with non-native sounds. Monolingual French speakers were trained to produce two non-native vowels: the Danish /ɔ/, which is similar to the French /o/, and the Russian /ɨ/, which is dissimilar from French vowels. We examined relation...

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...

This study examines the acoustic characteristics of English high tense and lax vowels (/i, I, u, ʊ/) and the perceptual difference of those vowels between English speakers and Korean speakers of English. In Experiment I, the first three formant values and duration of the four vowels in /hVd/ carrier were measured. The result shows that the high tense vowels have larger F2–F1 values and longer d...

Native Spanish speakers and Canadian English learners of Spanish produced the five Spanish vowels in utterance final /sV/ syllables. The syllables were presented in random order to Spanish and English listeners for identification of vowels in terms of Spanish vowel categories. The English listeners also identified the vowels in terms of English vowel categories. Initial analysis of perceptual r...

Strong and weak syllables in English can be distinguished on the basis of vowel quality, of stress, or of both factors. Critical for deciding between these factors are syllables containing unstressed unreduced vowels, such as the first syllable of automata. In this study 12 speakers produced sentences containing matched sets of words with initial vowels ranging from stressed to reduced, at norm...

The purpose of this study is to illustrate certain features of the place of articulation of Japanese vowels on the basis of formant frequency. For this purpose, two types of relationship between vowel duration and formant frequency were examined. The first of these relationships was the correlation between speaking rate and formant frequency. The result of this analysis showed that as speaking ...

This study investigates the acoustic and perceptual consequences of nasal coarticulation in American English. Nasalized (coarticulated) vowels were found to be closer in the F1-F2 acoustic vowel space than corresponding oral (non-coarticulated) vowels, indicating that contrast is reduced in the nasal vowel space, relative to the oral vowel space. With respect to perception, listeners are, perha...

This paper describes the vowels characteristics of three languages of Nagaland namely Nagamese, Ao and Lotha. For this study, nucleus vowel duration, formant structure (1 st and 2 nd formant i.e. F1 and F2) and intensity of vowels are investigated and analyzed for these languages. This paper includes the nasal context for different vowels and tries to examine its importance in different languag...
