Through providing an external support to speech, gesture observation may benefit a student's learning in a variety of areas, including narrative comprehension. Across two studies, we investigated factors that could moderate when gestures are most beneficial to narrative comprehension, including gesture type, task difficulty, and age, in order to…

This dissertation study explored the feasibility of using authenticated spoken texts to test L2 Chinese listening comprehension. The spoken texts used in the study were created using an "authenticating" technique, in which scripted spoken Chinese texts were infused with characteristics of real-world, unscripted spoken Chinese. In the…

Purpose: This study investigated whether listener processing of dysarthric speech requires the recruitment of more cognitive resources (i.e., higher levels of listening effort) than neurotypical speech. We also explored relationships between behavioral listening effort, perceived listening effort, and objective measures of word transcription…

Purpose: Listeners shift their listening strategies between lower level acoustic information and higher level semantic information to prioritize maximum speech intelligibility in challenging listening conditions. Although increasing task demands via acoustic degradation modulates lexical-semantic processing, the neural mechanisms underlying…

In this review article, we discuss the construct of second language (L2) comprehensibility, which refers to listeners' judgments of ease or difficulty in understanding L2 speech. We first briefly describe intelligibility and comprehensibility, two measures that capture listener understanding of L2 speech. We then present evidence that supports the…

Current second language (L2) listening research has lacked detailed accounts of L2 listeners' difficulties comprehending texts comprising orthographically known lexis. In the current study, 15 first language (L1) Japanese English language learners of three English proficiency levels listened to sentences and a narrative text. A two-task diagnostic…

This study examined the influence of formulaic language on second language (L2) listeners' lower-level processing, in terms of their ability to accurately identify the words in texts. On the one hand, there were reasons for expecting the presence of the formulas to advantage the learners, because the learners would process these formulaic words…

It is a common finding across languages that young children have problems in understanding patient-initial sentences. We used Tagalog, a verb-initial language with a reliable voice-marking system and highly frequent patient voice constructions, to test the predictions of several accounts that have been proposed to explain this difficulty: the…

This paper introduces a new captioning tool, Partial and Synchronized Caption with Hints (PSCH), as a means to facilitate second language (L2) listening by providing cues for ambiguous and difficult words/phrases in the caption while filtering out the easy words. Each word in the caption is synchronized to the corresponding audio to enable…

Automatic Speech Recognition (ASR) technology has become a part of contemporary Computer-Assisted Language Learning (CALL) systems. ASR systems however are being criticized for their erroneous performance especially when utilized as a mean to develop skills in a Second Language (L2) where errors are not tolerated. Nevertheless, these errors can…

When people say that what they hear is "over their heads," they are describing a severe information-based complexity (I-BC) problem. They cannot understand what is said because some of the information needed is missing, contaminated, and/or costly to obtain. Students often face these I-BC problems, and teachers often exacerbate them. Yet…

Controlling the rate of oral delivery in the second language classroom has been demonstrated as beneficial to the learner, whose information-processing capacity is an important factor in listening comprehension. Rate of information delivery can be controlled by limiting the actual rate of words per unit of time, or by maintaining content…
