A single session of vocalizing through a straw (straw phonation) has been associated with consistent or increased acoustic output and chorister-reported improved choral sound and vocal efficiency. Some choristers, however, report discomfort from the intense pressure of vocalizing through a stirring straw (2.5-3.0 mm opening). It is unclear whether…

This study employed a multisite design to investigate the differential impact of deductive and guided inductive instruction for second language (L2) grammar development in ecologically valid classroom contexts. Students (n = 138) from eight intact third-year L2 Spanish classes in three public high schools in the United States received deductive…

Prosody is a linguistic feature in spoken English that is complex yet plays an important role in oral communication. Nevertheless, many EFL pronunciation classes in Thailand have not adequately emphasized the importance and functions of prosody to learners. This research study aims to investigate effect of an oral fluency instructional method…

One of the aspects of L2 English phonology which poses a challenge for L2 learners is learning how to decode the language, especially as spoken by native speakers. This difficulty may be due to the way the native speakers speak by 'draw[ing] [the sounds] together' (Clarey & Dixson, 1963), which results in realization of consonants and vowels…

This dissertation investigated the effects of technological mediation on second language (L2) learning, focusing, as a case study, on gains in listening perception of the subtle but important feature of pitch placement in Japanese. Pitch accent can be difficult to perceive for non-native speakers whose first language (L1) does not rely on pitch or…

To be effective second or additional language (L2) listeners, learners should be aware of typical processes in connected L2 speech (e.g. linking). This longitudinal study explored how learners' developing ability to perceive connected L2 speech was related to the quality of their language awareness. Thirty-two learners of L2 French at a university…

The current study investigated how recasts can promote the L2 pronunciation development of word-initial /?/ by Japanese learners of English in relation to two developmental stages of English /?/ acquisition (i.e. change in second formant [F2] ? change in third formant [F3]) as well as four affecting variables (i.e. the amount of recasts and…

Language and literacy skills are instrumental to success at school and early success with writing is a key factor in literacy development. By eight years of age, children spend up to half of their school day engaged in writing tasks suggesting that those who find learning to write difficult may be disadvantaged. The ability to hear and record…

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…

Recent psycholinguistic findings showed that (a) a multi-modal phonetic training paradigm that encodes visual, interactive information is more effective in training L2 learners' perception of novel categories, (b) decreasing the acoustic variance of a phonetic dimension allows the learners to more effectively shift the perceptual weight towards…
