Acoustic 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 کاملAcoustic Characteristics of Japanese Vowels
The purpose of this study was to build a large database on Japanese vowels and to clarify their acoustic characteristics. Recordings were made of 256 males and 252 females aged from 6 to 76 years old, for both Kanto (Tokyo) and Kansai (Osaka) dialects, producing the vowels /i, e, a, o, u/ in isolation, in /h-Vda/ syllables and in /b-V-ta/ syllables within and without a carrier sentence. The fiv...
متن کاملArticulatory characteristics of Hungarian 'transparent' vowels
Using a combination of magnetometry and ultrasound, we examined the articulatory characteristics of the so-called 'transparent' vowels [i], [i], and [e] in Hungarian vowel harmony. Phonologically, transparent vowels are front, but they can be followed by either front or back suffixes. However, a finer look reveals an underlying phonetic coherence in two respects. First, transparent vowels in ba...
متن کاملAcoustic characteristics of American English vowels.
The purpose of this study was to replicate and extend the classic study of vowel acoustics by Peterson and Barney (PB) [J. Acoust. Soc. Am. 24, 175-184 (1952)]. Recordings were made of 45 men, 48 women, and 46 children producing the vowels /i,I,e, epsilon,ae,a, [symbol: see text],O,U,u, lambda,3 iota/ in h-V-d syllables. Formant contours for F1-F4 were measured from LPC spectra using a custom i...
متن کاملThe Effect of Vocal Loudness on Nasalance of Vowels in Persian Adults
Objectives: Nasality is one of the important parameters in pathology of voice resonance. Voice of normal adults has nasality to some extent. It appears that nasality, like other parameters of voice, can be affected by loudness which can be measured in experimental evaluations. This study was conducted to determine the effect of vocal loudness on nasalance of vowels in normal adults and to ident...
