This study explores the relationship between identification, degree of nasality and vowel quality in oral, nasal and nasalized vowels in Brazilian Portuguese. Despite common belief that the language possesses contrastive nasal vowels, literature examination shows that nasal vowels may be followed by a nasal resonance, while nasalized vowels must be followed by a nasal consonant. It is argued th...

This study investigated whether individuals with small and large native-language (L1) vowel inventories learn second-language (L2) vowel systems differently, in order to better understand how L1 categories interfere with new vowel learning. Listener groups whose L1 was Spanish (5 vowels) or German (18 vowels) were given five sessions of high-variability auditory training for English vowels, aft...

this article addresses the perceptual correlates of compensatory lengthening in persian. in a perception experiment, duration, spectral tilt measurements h1-h2 and h1-f1 and f0 were varied in several steps based on the results from a production experiment (sadeghi, 2007). subjects were asked to identify the tokens involving vowel length. results revealed that duration is the most reliable perce...

The present study basically conducted a qualitative-oriented research to identify the articulating and listening problems of eleven AE vowels for Taiwanese eighth graders. It aimed to examine the relationship between production and perception of English vowels. Gender differences were probed under this sound pronunciation and discrimination framework. A vowel articulating test followed by a vow...

Research suggests that the size of the second language (L2) vowel inventory relative to the native (L1) inventory may affect the discrimination and acquisition of L2 vowels. Models of non-native and L2 vowel perception stipulate that naïve listeners' non-native and L2 perceptual patterns may be predicted by the relationship in vowel inventory size between the L1 and the L2. Specifically, having...

Most of researches have reported the significance English phonemic awareness to success learning English, but less discussions involving students with visual disabilities. Students disabilities lacks input and form a strong sensitivity audio input, that this condition affect their spelling ability, yet, ability in recognizing phonemes has been explored especially Indonesia. Thus, research aims ...

Do vowel-contingent selective adaptation effects for place of articulation depend on vowel identity, or on the particular formant frequencies used? An experiment is reported here which tested the adaptation effects of consonants with exactly the same formant transitions before different diphthongs. In this experiment, the phonetic identity of the vowel and the formant frequencies of the consona...

The main purpose of this study was to compare acoustically the vowel spaces of two groups of cochlear implantees (CI) with two age-matched normal hearing groups. Five young test persons (15-25 years) and five older test persons (55-70 years) with CI and two control groups of the same age with normal hearing were recorded. The speech material consisted of five German vowels V = /a, e, i, o, u/ i...

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...
