This study examines Korean L2 learners' production of English phonological contrasts (e.g., consonant-final versus vowel-final forms) that are absent in their L1. Twenty university students divided into high- and low-proficiency groups participated in the study. Their productions were analyzed for segmental accuracy and error patterns. Results…

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…

Arabic emphasis refers to the production of consonants resulting from a primary constriction in the dental or alveolar region and a secondary constriction in the back of the vocal tract, recognized as 'Emphatic.' These have contrastive consonants produced in the dental or alveolar region, recognized as 'Plain.' The existing research on emphasis in…

This dissertation investigates language-specific acoustic and aerodynamic phenomena in language contact situations. Whereas most work on second language and bilingual phonology has focused on individual consonants and vowels, this project examines patterns of coarticulation in the two languages of Spanish-English and French-English bilingual…

Children are known to be fast learners due to their neural plasticity. Learning a non-native language (L2) requires the mastering of new production patterns. In classroom settings, learners are not only exposed to the acoustic input, but also to the unfamiliar grapheme-phoneme correspondences of the L2 orthography. We tested how 9-10-year-old…

Research attempting to understand the intermediate stages of first-language acquisition and disordered speech has led to the discovery of covert contrast. A covert contrast is a statistically reliable difference between phonemes that is produced by a language learner, but in a way that cannot be heard readily by a listener of the target language.…

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…

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…

Some syllables are louder, longer and stronger than other syllables at the lexical level. These prominent prosodic characteristics of certain syllables are captured by suprasegmental features including fundamental frequency, duration and intensity. A language like English uses fundamental frequency, duration and intensity to distinguish stressed…

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…

College students' pronunciations of initial "c" and "g" were examined in English words and nonwords, both monosyllables and polysyllables. Pronunciations were influenced by adjacent context--whether the following letter was "e" or "i"--and by long-distance context--whether the item contained a suffix or spelling pattern characteristic of Latinate…

A descriptive model elaborated to account for the rhythmic organization of French and English is applied to the speech of French learners of English to identify the particular type of cross-linguistic influence operating therein. Evidence is presented for the existence of transitional rhythmic groups, perceived in the interlanguage vowel reduction…

This study explores the relationships between a child's discriminatory abilities in the areas of pitch, intensity, rhythm, timbre, and tonal memory and his capacity to comprehend and speak the Spanish language. The Spanish accent is analyzed on the basis of intonation, stress, sinalepha, and phone production. These factors were tested both in…

A study investigated to what extent adult native speakers of Mandarin Chinese learning English as a second language could pronounce the five front vowels of American English, how difficult this was, and which vowels were most difficult. Subjects were 16 Chinese university students and spouses and 16 American students. All subjects were recorded…

Recent findings from the fields of brain research and speech perception suggest that non-verbal approaches may be helpful in pronunciation learning. The left side of the brain uses sequential information, such as verbal descriptions. The right side works in a more simultaneous manner, specializing in spatial relations and pitch perception, among…
