Positive Effect

The effectiveness of a high variability identification training procedure to improve native Japanese identification and production of the American English (AE) mid and low vowels /æ/, //, //, //, // was investigated. Vowel identification and production performance for two groups of Japanese participants was measured before and after a 6-week identification training period. Recordings were made of both group's pre-/posttraining vowel productions of the five vowels, which were evaluated by a group of native AE listeners using a five-alternative, forced-choice identification task and by an acoustic analysis of the vowel productions. The overall results confirmed that the identification performance of the experimental (trained) participants improved after identification training with feedback and that the training also had a positive effect on their production of the target AE vowels.

Indonesian is the most widely spoken language in Indonesia. More than 200 million people speak the language as a first language. However, acoustic study on Indonesian learners of English (ILE) production remains untouched. The purpose of this measurement is to examine the influence of first language (L1) on English vowels production as a second language (L2). Based on perceptual magnet hypothesis (PMH), ILE were predicted to produce close sounds to L1 English where the vowels are similar to Indonesian vowels. Acoustic analysis was conducted to measure the formant frequencies. This study involved five males of Indonesian speakers aged between 20-25 years old. The data of British English native speakers were taken from previous study by Hawkins & Midgley (2005). The result illustrates that the first formant frequencies (F1) which correlates to the vowel hight of Indonesian Learners of English were significantly different from the corresponding frequencies of British English vowels. Surprisingly, the significant differences in second formant (F2) of ILE were only in the production of /ɑ, ɒ, ɔ/ in which /ɑ/=p 0.002, /ɒ/ =p 0,001, /ɔ/ =p 0,03. The vowel space area of ILE was slightly less spacious than the native speakers. This study is expected to shed light in English language teaching particularly as a foreign language.Keywords: VSA, EFL, Indonesian learners, formant frequencies, acoustic

This study aims at discussing the phonetic property of vowel quality in English, as exercised by both native speakers of General American English (AE) and non-native speakers of General American English of Serbian language background, all residents of the United States. Ten Serbian male speakers and four native male speakers of AE are recorded in separate experiments and their speech analyzed acoustically for any significant phonetic differences, looking into a set of monosyllabic English words representing nine vowels of AE. The general aim of the experiments is to evaluate the phonetic characteristics of AE vowels, with particular attention to F1 and F2 values, investigate which vowels differ most in the two groups of participants, and provide some explanations for these variations. A single most important observation that is the result of this vowel study is an evident merger of three pairs of vowels in the non-native speech: /i ɪ/, /u ʊ/, and /ɛ æ/.

Acoustic analysis tests the hypothesis that the physical properties of Pakistani English (PaKE) vowels differ in terms of acoustic measurements of Native American English speakers. The present paper aims to document the physical behavior of English vowels produced by PaKE learners. The major goal of this paper is to measure the production of sound frequencies coupled with vowel duration. The primary aim of this paper is to explore the different frequencies and duration of the vowels involved in articulation of PaKE. English vowels selected for this purpose are: /æ/, /ɛ/, /ɪ/, /ɒ/ and /ə/. Total ten samplings were obtained from the department of computer science at Sindh Madressatul Islam University, Karachi. The study was based on the analysis of 500 (10×5×10=500) voice samples. Five vowel minimal pairs were selected and written in a carrier phrase [I say CVC now]. Ten speakers (5 male & five female) recorded their 500 voice samples using Praat speech processing tool and a high-quality microphone on laptop in a computer laboratory with no background sound. Three parameters were considered for the analysis of PaKE vowels i.e., duration of five vowels, fundamental frequency (F1 and F2). It was hypothesized that the properties of PaKE vowels are different from that of English native speakers. The hypothesis was accepted since the acoustic measurements of PaKE and English Native American speakers’ physical properties of sounds were discovered different.

University Level

The current study presents acoustic analyses of non-high back vowels and low central vowels in the lexical sets LOT, THOUGHT, STRUT, PALM and BATH as pronounced by German learners of English. The main objective is to show that learners of English at university level are highly inconsistent in approximating the vowels of their self-chosen target accents British English (BrE) and American English (AmE). To that end, the acoustic qualities of the English vowels of learners are compared to their native German vowels and to the vowels of native speakers of BrE and AmE. In order to facilitate statements about the effect of increased experience, the study differentiates between students in their first year at university and in their third year or later. The results obtained are highly variable: In some cases the learners transfer their L1 vowels to English, other cases show clear approximations to the target vowels, while other cases again document the production of new vowels neither found in German nor in English. However, close approximation to the target vowels only sometimes correlates with higher proficiency. This might be an indicator of a low level of awareness of systematic differences between the BrE and AmE vowel systems. But the data also indicate that the more advanced learners produce more distinct AmE BATH vowels and BrE THOUGHT vowels than the less advanced learners, which points to a partial increase of awareness resulting from increased experience. All in all it seems that raising the awareness of differences between target accents in L2 instruction is necessary if the envisage goal is for learners to reach near-native pronunciation.

Adaptive Recognition

When native speakers of Japanese are taught English as a second language, there are difficulties with their training in pronunciation of American English vowels that can be ameliorated though adaptive recognition of the learner’s vowel space. This paper reports on the development of an online Computer-Assisted Language Learning (CALL) environment that provides Japanese learners with customized target utterances of 12 single-syllable words that are synthesized according to an adaptive recognition of the learner’s vowel space. These customized target utterances provide each learner with examples of each of 12 American English monophthongs in consonant-vowel-consonant (CVC) context in order to sound as if they had been uttered by the learners themselves. This adaptive process was incorporated into a successfully developed tool for Computer-Assisted Pronunciation Training (CAPT) which gave more appropriate pronunciation targets to each learner, rather than forcing the learners to attempt to match the formant frequencies of their own utterances to those of the target utterances as produced by a speaker exhibiting a different vowel space (i.e., a speaker with a different vocal tract length).

This study examined intelligibility of twelve American English vowels produced by English, Chinese, and Korean native speakers in quiet and speech-shaped noise in which vowels were presented at six sensation levels from 0 dB to 10 dB. The slopes of vowel intelligibility functions and the processing time for listeners to identify vowels were dependent on speakers’ language backgrounds and non-native speakers’ vowel intelligibility in quiet. These results indicated that noise background affected non-native speakers’ vowel intelligibility more greatly than native speakers, possibly due to the acoustic deviations in non-native speech and lack of listeners’ experience to non-native produced speech.
