Automatic Speech Scoring (ASS) has increasingly become a useful tool in oral proficiency testing for Second Language (L2) learners. However, limited studies investigate the alignment of ASS indices with the Complexity, Accuracy, and Fluency (CAF)--the three dimensions in evaluating L2 speakers' oral proficiency, and the subsequent impact indices…

Adult second language (L2) learning often exhibits great variability in its rate and outcome. Although research shows that learning trajectories are partly shaped by social and contextual factors (e.g. Larson-Hall, 2008), certain learner factors play an important role in enhancing L2 pronunciation learning by helping L2 learners notice and process…

Learners' anxiety has drawn widespread attention in the field of second language/foreign language (L2/FL) teaching and learning (e.g. classroom anxiety, communication (with foreigners) anxiety, and anxiety associated with the four macro-skills, namely listening, reading, speaking, and writing). However, this topic is under-explored in L2/FL public…

There is a scarcity of research into the relationship between speech perception and production from a multilingual perspective. The present exploratory study investigates longitudinally the acquisition of rhotic sounds in 24 adolescent learners who have the same language repertoires (English, German, Polish), with English being their L2, and…

Communication in a second or multiple languages has become essential in the globalized world. However, acquiring a second language (L2) after a critical period is universally acknowledged to be challenging (Lenneberg, 1967). Late learners hardly reach a nativelike level in L2, particularly in its pronunciation, and their incomplete phonological…

This study investigated the impact of English Language proficiency testing on the pronunciation performance of undergraduates in South-west. Nigeria. The study was a descriptive survey research design. The target population size was 1243 (200-level) undergraduates drawn from eight tertiary institutions. The instruments used for data collection…

The study aimed at investigating the effects of autonomous pronunciation learning using AI as well as the experiences of autonomous pronunciation learning using AI by higher level students. Explanatory sequential mixed-method research using both quantitative and qualitative methods was employed within thirty-two students from Universitas PGRI…

We investigate the interrelations between pronunciation and writing skills in French as a foreign language produced by two groups of bilingual learners (German-Russian; German-Turkish) and a monolingually raised German control group (each n = 10). As an indicator of the learners' pronunciation skills, we refer to a perceptually relevant acoustic…

Studies of the acquisition of the lenited allophones of Spanish voiced stops have traditionally focused on the production (Lord, 2010; Rogers & Alvord, 2014; Zampini, 1994), but not on the perception of these sounds. This pilot study examines relationships between (a) learner proficiency and perception of target sounds; (b) learner perception…

Research has suggested the important role of vocabulary knowledge in second language (L2) speaking proficiency. However, earlier studies tended to disregard the congruence in test format between assessing vocabulary knowledge and speaking skills with the former predominantly measured in written format. The current study measured vocabulary…

While previous work has shown a relationship between pronunciation attitudes and pronunciation performance, the connection between language learning motivation and pronunciation attitudes has been underexplored. This study investigated the relationship between 195 foreign language learners' attitudes toward pronunciation, the foreign languages…

Over the last two decades, there has been an increasing interest in third language (L3) phonology (Cabrelli Amaro, 2012; Cabrelli Amaro & Wrembel, 2016). However, research so far has been primarily directed at specific stages of learning and has independently explored either production (e.g., Llama, Cardoso, & Collins, 2010; Llama &…

The present study aims to reveal the effects of test type, pronunciation and proficiency levels of the students on speaking test scores. A total of 147 Turkish EFL students consisting of 38 beginner, 36 elementary, 37 pre-intermediate and 36 intermediate levels participated in the study. Presentation as planned, and paired speaking test as…

This dissertation research examines the acquisition of second language vowels. For second language learners, learning a new languages' sound inventory, particularly its vowels, presents a challenge perceptually and in terms of production. Incorrectly perceiving and producing sounds in a second language results in a foreign accent in many adult…

To date, a growing number of studies have shown that domain-general auditory processing, which prior work has linked to L1 acquisition, could explain various dimensions of naturalistic L2 speech proficiency. The current study examined the generalizability of this topic to L2 speech learning in classroom settings. The spontaneous speech samples of…
