Purpose: This study investigated the efficacy of ultrasound biofeedback compared to a traditional acoustic input-only method in the second-language (L2) production training of English tense-lax vowel contrasts (/i-[near-close near-front unrounded vowel]/ and /e-[open-mid front unrounded vowel]/). The relationship between the degrees of production…

This dissertation examines the development of the internal structure of the Korean syllable by adult Korean learners whose native language is English. Prior research has identified the prominence of the body constituent in Korean and the rime constituent in English. The current study focuses on the acquisition of the body unit by English speakers…

The speech of second language learners is often influenced by phonetic patterns of their first language. This can make them difficult to understand, but sometimes for listeners of the same first language to a lesser extent than for native listeners. The present study investigates listeners' awareness of the accent by asking whether accented speech…

Perceptual assimilation is a well-known task; however, there is no study on the assimilation pattern of the English monophthongs by L2 Thai learners. The aims of this study are to explore the perceptual assimilation patterns of the British English monophthongs to Thai monophthongs by L2 Thai learners and to examine the effect of L2 experience on…

The three types of stresses namely "word stress," "compound stress" and "phrasal stress" are the key elements to determine the exact means of conveying a specific intent in an utterance. Therefore during perception and production of such meaning carrying codes, being able to use the right stress pattern is vitally…

Teaching pitch patterns of English as part of one of the elements of intonation has considerably been undervalued in Turkish teacher education contexts despite its significance in communication (Roach, 2001; Scherer, 2003; Maastricht et al., 2016) hence less research was conducted on this subject (Wennerstrom, 2001; Pickering, 2002; Demirezen,…

This paper includes two interrelated studies. The first production study investigates the timing patterns of English as spoken by Chinese learners with different dialect backgrounds. The second comprehension study explores native and non-native speakers' assessments of the intelligibility of Chinese-accented English, and examines the effects of…

We present the outcomes of a pronunciation training program conducted in a workplace setting with second language speakers who had lived in an English-speaking environment for an average of 19 years. The research questions concerned whether improvement would occur in the learners' perception of certain segments and prosody; in the…

What are the effects of experience on subsequent learning? We explored the effects of language-specific word order knowledge on the acquisition of sequential conditional information. Korean and English adults were engaged in a sequence learning task involving three different sets of stimuli: auditory linguistic (nonsense syllables), visual…

Considering the contradictory research on explicit teaching of suprasegmentals, the present study aims to investigate the effects of explicit instruction of L2 English learners' perception of prosodically ambiguous intonation patterns, as well as the possible effects of reported musical familiarity on intonation acquisition. A control group and a…

This study investigated the effects of first language prosodic transfer on the perception and production of English lexical stress and the relation between stress perception and production by second language learners. To test the effect of Thai tonal distribution rules and stress patterns on native Thai speakers' perception and production of…

A study examines two major types of vowel systems in languages, centripetal and centrifugal. English is associated with the centripetal system, in which vowel quality and quantity (rhythm) are heavily influenced by stress. In this system, vowels have a strong tendency to move toward the center of the vowel area. Spanish is associated with the…

Because listening is a vital part of language learning, listening skills should be developed as a learning mode. Pre-listening skills should be taught just as pre-reading skills are taught. Children in command of the auditory perceptual abilities which contribute most to listening will transfer these abilities to increasingly difficult listening…
