A systematic review of technology-enhanced L2 listening development since 2000

Since 2000, technology-enhanced L2 listening development (TELD) has been increasingly investigated. However, systematic reviews concerning the technologies, learning tasks, and outcomes of TELD remain limited. To fill this gap, we conducted a systematic review of publications from 2000 to 2022 on TELD from the perspectives of technologies, learning tasks, and learning outcomes. Forty-six articles from Web of Science were screened by predefined criteria and analysed based on a step-by-step procedure using the PRISMA framework. The findings revealed 13 types of technology and 19 learning tasks useful for TELD. TELD was effective both in terms of building listening skills and enhancing learner emotions. The studies showed that TELD supported learner interactions, encouraged active engagement, and augmented various learning tasks. Based on the findings, we developed a TELD model consisting of two parts: “Within cognitive systems,” in which learners deal with cognitive schemata, listening strategy application, and listening practice via solid attention; “outside of cognitive systems,” in which TELD can construct and reconstruct cognitive schemata, support listening practices, encourage and guide listening strategy application, and improve learner emotions and attention by providing learning materials and activities based on listening-related knowledge, listening exercises with feedback, prompts and feedback on listening strategy application, and a sense of enjoyment and comfort

Towards Universally Designed Communication: Opportunities and Challenges in the Use of Automatic Speech Recognition Systems to Support Access, Understanding and Use of Information in Communicative Settings

Unlike physical barriers, communication barriers do not have an easy solution: people speak or sign in different languages and may have wide-ranging proficiency levels in the languages they understand and produce. Universal Design (UD) principles in the domain of language and communication have guided the production of multimodal (audio, visual, written) information. For example, UD guidelines encourage websites to provide information in alternative formats (for example, a video with captions; a sign language version). The same UD for Learning principles apply in the classroom, and instructors are encouraged to prepare content to be presented multimodally, making use of increasingly available technology. In this chapter, I will address some of the opportunities and challenges offered by automatic speech recognition (ASR) systems. These systems have many strengths, and the most evident is the time they employ to convert speech sounds into a written form, faster than the time human transcribers need to perform the same process. These systems also present weaknesses, for example, a higher rate of errors when compared to human-generated transcriptions. It is essential to weigh the strengths and weaknesses of technology when choosing which device(s) to use in a universally designed environment to enhance access to information and communication. It is equally imperative to understand which tools are most appropriate for diverse populations. Therefore, researchers should continue investigating how people process information in a multimodal format, and how technology can be improved based on this knowledge and users’ needs and feedback

Re-examining Phonological and Lexical Correlates of Second Language Comprehensibility:The Role of Rater Experience

Few researchers and teachers would disagree that some linguistic aspects of second language (L2) speech are more crucial than others for successful communication. Underlying this idea is the assumption that communicative success can be broadly defined in terms of speakers’ ability to convey the intended meaning to the interlocutor, which is frequently captured through a listener-based rating of comprehensibility or ease of understanding (e.g. Derwing & Munro, 2009; Levis, 2005). Previous research has shown that communicative success – for example, as defined through comprehensible L2 speech – depends on several linguistic dimensions of L2 output, including its segmental and suprasegmental pronunciation, fluency-based characteristics, lexical and grammatical content, as well as discourse structure (e.g. Field, 2005; Hahn, 2004; Kang et al., 2010; Trofimovich & Isaacs, 2012). Our chief objective in the current study was to explore the L2 comprehensibility construct from a language assessment perspective (e.g. Isaacs & Thomson, 2013), by targeting rater experience as a possible source of variance influencing the degree to which raters use various characteristics of speech in judging L2 comprehensibility. In keeping with this objective, we asked the following question: What is the extent to which linguistic aspects of L2 speech contributing to comprehensibility ratings depend on raters’ experience

Lexical profiles of comprehensible second language speech: the role of appropriateness, fluency, variation, sophistication, abstractness and sense relations

This study examined contributions of lexical factors to native-speaking raters’ assessments of comprehensibility (ease of understanding) of second language (L2) speech. Extemporaneous oral narratives elicited from 40 French speakers of L2 English were transcribed and evaluated for comprehensibility by 10 raters. Subsequently, the samples were analyzed for 12 lexical variables targeting diverse domains of lexical usage (appropriateness, fluency, variation, sophistication, abstractness, and sense relations). For beginner-to-intermediate speakers, comprehensibility was related to basic uses of L2 vocabulary (fluent and accurate use of concrete words). For intermediate-to-advanced speakers, comprehensibility was linked to sophisticated uses of L2 lexis (morphologically accurate use of complex, less familiar, polysemous words). These findings, which highlight complex associations between lexical variables and L2 comprehensibility, suggest that improving comprehensibility requires attention to multiple lexical domains of L2 performance

Lexical correlates of comprehensibility versus accentedness in second language speech

The current project investigated the extent to which several lexical aspects of second language (L2) speech – appropriateness, fluency, variation, sophistication, abstractness, sense relations – interact to influence native speakers’ judgements of comprehensibility (ease of understanding) and accentedness (linguistic nativelikeness). Extemporaneous speech elicited from 40 French speakers of English with varied L2 proficiency levels was first evaluated by 10 native-speaking raters for comprehensibility and accentedness. Subsequently, the dataset was transcribed and analyzed for 12 lexical factors. Various lexical properties of L2 speech were found to be associated with L2 comprehensibility, and especially lexical accuracy (lemma appropriateness) and complexity (polysemy), indicating that these lexical variables are associated with successful L2 communication. In contrast, native speakers’ accent judgements seemed to be linked to surface-level details of lexical content (abstractness) and form (variation, morphological accuracy) rather than to its conceptual and contextual details (e.g., lemma appropriateness, polysemy)

FLAX: Flexible and open corpus-based language collections development

In this case study we present innovative work in building open corpus-based language collections by focusing on a description of the opensource multilingual Flexible Language Acquisition (FLAX) language project, which is an ongoing example of open materials development practices for language teaching and learning. We present language-learning contexts from across formal and informal language learning in English for Academic Purposes (EAP). Our experience relates to Open Educational Resource (OER) options and Practices (OEP) which are available for developing and distributing online subject-specific language materials for uses in academic and professional settings. We are particularly concerned with closing the gap in language teacher training where competencies in materials development are still dominated by print-based proprietary course book publications. We are also concerned with the growing gap in language teaching practitioner competencies for understanding important issues of copyright and licencing that are changing rapidly in the context of digital and web literacy developments. These key issues are being largely ignored in the informal language teaching practitioner discussions and in the formal research into teaching and materials development practices

Investigating the impact of segmented and whole-text repetition on listening comprehension, comprehension processes, and comprehension problems

This dissertation presents a product- and process-oriented approach to investigating how a common teaching methods used in second language listening classrooms--repetition--might be structured in a way that enhances listening comprehension and facilitates input processing. The major purpose of the dissertation was to investigate the impact of both whole-text and semantically segmented repetition on English as a Second Language (ESL) learners\u27 listening comprehension and comprehension problems. An embedded, mixed-methods approach was employed in the study. Quantitative data consisted of written recalls from 100 intermediate-level, ESL participants who each listened to two, authentic lecture excerpts in one of the two aforementioned conditions. Qualitative data consisted of verbal protocols and post-task interviews with 12 participants. The findings indicate that there was no statistically significant difference between overall recall scores (i.e., summed recall scores for the two texts) for students in the two conditions. When recall scores for each lecture were compared individually, the results mirrored those found when looking at the scores overall in terms of statistical significance. Despite the lack of statistical significance from the recalls, findings from the verbal protocol data largely supported the hypotheses that students in the whole-text condition would encounter more problems attending to the task and forming a mental representation of the input compared to students in the segmented condition who were provided with more guidance in attending to the task and structure building through the task\u27s design. The results from the study were mixed in terms of supporting and refuting the claims in previous literature. However, both the findings and methods from the study hold a number of implications and recommendations for language teachers, materials developers, those interested in the use of technology for language learning and assessment, and future researchers
