Phoneme detection experiments, in which listeners' response time to detect a phoneme target is measured, have typically used consonant targets. This paper reports two experiments in which subjects responded to vowels as phoneme detection targets. In the first experiment, targets occurred in real words, in the second in nonsense words. Response times were long by comparison with consonant target...

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...

Kwon, Harim. 2007. A F'honetic Analysis of Korean EFL, Learners' Production of English Reduced Vowel. SNU Working Papers i n English Linguistics and Language 6, 1-13. This study investigates the phonetic properties of English reduced vowel of Korean EFL learners. Five native speakers of Korean (experimental group) and two native speakers of English (control group) participated in the study. Whi...

The aim of the present paper is to study the status of the short vowels /i/ and /u/ in five selected Iranian Balochi dialects. These dialects are spoken in Sistan (SI), Saravan (SA), Khash (KH), Iranshahr (IR), and Chabahar (CH) regions located in province Sistan va Baluchestan in the southeast of Iran. This study investigates whether these two vowels have the same qualities as the short /i/ an...

This paper reports on a system created to help language students learn the vowel inventory of Swedish. Formants are tracked, and a 3D ball moves over a vowel-chart canvas in real time. Target spheres are placed at the target values of vowels, and the students’ task is to get the target spheres. A calibration process of capturing data from three cardinal vowels is used to normalize the effects o...

It has been claimed that segments are 'strongly' articulated in two prosodic positions: pitch-accented syllables [4, 5] and domaininitial positions [3, 6, 7, 9]. The current study examines the effect of these two prosodic conditions on resistance to vowel-to-vowel coarticulation, based on acoustic data. This study first shows that vowels are strongly articulated at the edges of prosodic domains...

________________________________________________________________________________________________________ Vowel lengthening in Belgium French: an experimental and perceptual approach This paper investigates the lengthening of certain vowels in Belgian French and its influence on the perception of a Belgian accent. Based on recordings made in Belgium, two perceptual experiments were conducted, in...

Eight speakers (4 male and 4 female) of the Muskogee dialect of Creek pronounced a set of words illustrating the vowels and diphthongs of Creek. These recordings were analyzed acoustically and data on vowel duration and vowel formant frequencies are presented in this paper. The ratio of the durations of dictinctively long and short vowels was 1.8. This ratio showed a sex difference, being large...

The acoustic differences between Afrikaans and South African English, spoken as first (L1) and second (L2) language, are measured for nine short vowels. The spoken language data base of 22 male speakers, collected for comparative studies, is described. The features used in an initial comparison of the isolated vowels and vowels in CVC words are the first three formant values and ratios. Signifi...
