Background/Objectives: While machine learning has made substantial strides in pronunciation detection in recent years, there remains a notable gap in the literature regarding research on improvements in the acquisition of speech sounds following a training intervention, especially in the domain of perception. This study addresses this gap by developing a deep learning algorithm designed to identify perceptual gains resulting from second language (L2) phonetic training. Methods: The participants underwent multiple sessions of high-variability phonetic training, focusing on discriminating challenging L2 vowel contrasts. The deep learning model was trained on perceptual data collected before and after the intervention. Results: The results demonstrated good model performance across a range of metrics, confirming that learners’ gains in phonetic training could be effectively detected by the algorithm. Conclusions: This research underscores the potential of deep learning techniques to track improvements in phonetic training, offering a promising and practical approach for evaluating language learning outcomes and paving the way for more personalized, adaptive language learning solutions. Deep learning enables the automatic extraction of complex patterns in learner behavior that might be missed by traditional methods. This makes it especially valuable in educational contexts where subtle improvements need to be captured and assessed objectively. Full article

Background: A transfer of learning effects across speech perception and production is evident in second-language (L2)-learning research, suggesting that perception and production are closely linked in L2 speech learning. However, underlying factors, such as the phonetic cue weightings given to acoustic features, of the relationship between perception and production improvements are less explored. To address this research gap, the current study explored the effects of Mandarin tone learning on the production and perception of critical (pitch direction) and non-critical (pitch height) perceptual cues. Methods: This study tracked the Mandarin learning effects of Indonesian adult learners over a four-to-six-week learning period. Results: We found that perception and production gains in Mandarin L2 learning concurrently occurred with the critical pitch direction cue, F0 slope. The non-critical pitch height cue, F0 mean, only displayed a production gain. Conclusions: The results indicate the role of critical perceptual cues in relating tone perception and production in general, and in the transfer of learning effects across the two domains for L2 learning. These results demonstrate the transfer of the ability to perceive phonological contrasts using critical phonetic information to the production domain based on the same cue weighting, suggesting interconnected encoding and decoding processes in L2 speech learning.

The tonal system of Cantonese is very different from that of Mandarin, which creates potential challenges for Mandarin speakers when learning Cantonese. The aim of this study was to explore second language (L2) production of Cantonese tones by advanced learners whose first language (L1) is Mandarin. Forty-one informants participated in a recording experiment to provide production data of Cantonese tones. The speech data were measured acoustically using the computer software Praat (Version 6.3.10) and were evaluated perceptually by native Cantonese speakers. The relationship between the acoustic analysis and perceptual evaluation was also explored. The acoustic and perceptual evaluations confirmed that, while the tones that the Mandarin learners of Cantonese produced were non-native-like, their production of the Cantonese T1 and T2 was good in general. Furthermore, the accuracy of the perceptual evaluations could be predicted based on the acoustic features of the L2 tones. Our findings are in line with hypotheses in current speech learning models, and demonstrate that familiar phonetic categories are easier to acquire than are unfamiliar ones. To provide a more complete picture of L2 speech acquisition, future research should investigate L2 tone acquisition using both production and perception data obtained from participants with a greater variety of L1s.

Despite being fundamental for speech processing, L2 perceptual training often lacks attention in L2 classrooms, especially among English as Foreign Language (EFL) learners navigating complex English phonology. The current study investigates the impact of the blended phonetic training program incorporating HVPT features on enhancing L2 perception and listening comprehension skills in Korean elementary EFL learners. Fifty-seven learners, aged 11 to 12 years, participated in a four-week intervention program. They were trained on 13 challenging consonant phonemes for Korean learners, using multimedia tools for practice. Pre- and posttests assessed L2 perception and listening comprehension. They are grouped into three proficiency levels based on listening comprehension tests. The results showed significant improvements in L2 perception (p = 0.01) with small and in listening comprehension (p < 0.001) with small-to-medium effects. The lower proficiency students demonstrated the largest gains. The correlation between L2 perception and listening comprehension was observed both in pre- (r = 0.427 **) and posttests (r = 0.479 ***). Findings underscore the importance of integrating explicit phonetic instruction with HVPT to enhance L2 listening skills among EFL learners. Full article

Previous studies have found that second language learners can acquire sociolinguistic variation. However, there is a lack of studies that examine the L2 acquisition of second-person singular forms of address (2PS) in Spanish, especially in the immersion context of study abroad. The current study examines the acquisition of Spanish 2PS by seven adults learning Spanish in Medellin, Colombia. Participants completed an oral discourse completion task and a matched guise task to measure language perceptions toward each 2PS. Learners’ results are compared to findings from 38 native Spanish speakers from Medellin. Learners produced very few instances of the local variant vos and overproduced tú, differing greatly from native speakers. Two factors were found to significantly condition 2PS usage for learners: speaker gender and interlocutor relationship. Findings show that although learners perceive vos to a somewhat native-like extent and the role that it plays in the local variety, learners do not actually use it. Full article

This study examines the perception of insult-related vocabulary in Spanish among native speakers (L1) and Polish learners of Spanish as a foreign language (L2). Insults are analyzed as versatile speech acts fulfilling pragmatic functions such as impoliteness, affiliation, and emphasis. Adopting a contrastive approach, this research evaluates perceptions of colloquialism and emotional intensity across three groups: learners without prior stays in Spanish-speaking countries, learners with prior stays, and L1 speakers. Data were collected through surveys assessing knowledge, recognition, and perception of selected insults related to intellect and sexuality. The findings reveal that insults associated with sexuality exhibit the highest perceived offensive load across all groups, while those linked to behavior and intellect are rated as less aggressive. Polish learners of Spanish, particularly those without cultural immersion, tend to overestimate the offensiveness of insults compared to L1 speakers. However, learners with prior stays align more closely with L1 perceptions, underscoring the impact of cultural exposure. The results highlight the pivotal role of context and interlanguage in shaping learners’ interpretations of offensive vocabulary. They also establish a foundation for further exploration into the acquisition and pragmatic use of colloquial and emotionally charged language in L2 learning. Full article

In today’s globalized world, foreign language (FL) communication is characterized by the presence of regional variations that can impact L2 learners’ speech perception in their target language. While it is essential for FL programs to prepare their students for real-world language variation, research on learner perception of spoken regional varieties remains scarce, especially for less commonly taught languages, such as Italian. To address this, this study used a quantitative approach to explore to what extent listeners’ background factors (i.e., accent familiarity, contact with Italian speakers, heritage learner status, L1) and speaker accent impact FL learners’ perceptions of (1) intelligibility, (2) comprehensibility, and (3) acceptability of regionally accented Italian speech. A total of forty-seven FL learners of Italian listened to the speech of six Italian native speakers with different regional accents (two each from Northern, Central, and Southern Italy), rated them for comprehensibility and acceptability, and transcribed utterances for intelligibility. Mixed-effects models revealed statistically significant effects of speaker accent and listener L1 background on all three perceptual constructs. Additionally, greater contact corresponded with higher comprehensibility, while heritage learners rated speech as less acceptable for educational contexts. Listeners’ overall positive perception of regionally accented speech encourages the introduction of authentic spoken varieties in the FL classroom. Full article

The COVID-19 pandemic resulted in the widespread adoption of online instruction all around the world. In fact, in the post-pandemic era, online teaching and learning are proliferating and are considered as alternatives to traditional learning. The current study investigated L2 learners’ perceptions of an online pronunciation course. Sixty L2 learners, ranging in age from 18 to 60, were recruited from different intensive English programs (IEPs) across the United States and six other countries, including India, Brazil, China, France, Russia, and Canada. The participants received online-based computer-assisted pronunciation training (CAPT) on Moodle over a period of three weeks and completed an online survey on Qualtrics. The results of the quantitative and qualitative data collected from the learners at the end of the course showed that the learners were highly satisfied with their own performance and that they found the online course highly useful and preferred it over a face-to-face pronunciation course. The findings provide valuable insights into the design and delivery of online courses for pronunciation teachers. The findings also suggest that CAPT can effectively support asynchronous L2 pronunciation teaching. Full article

The present paper investigates the link between perception and production in the laryngeal phonology of multilingual speakers, focusing on non-contrastive segments and the dynamic aspect of these processes. Fourteen L1 Hungarian, L2 English, and L3 Spanish advanced learners took part in the experiments. The production experiments examined the aspiration of voiceless stops in word-initial position, regressive voicing assimilation, and pre-sonorant voicing; the latter two processes were analyzed both word-internally and across word boundaries. The perception experiments aimed to find out whether learners notice the phonetic outputs of these processes and regard them as linguistically relevant. Our results showed that perception and production are not aligned. Accurate production is dependent on accurate perception, but accurate perception is not necessarily transferred into production. In laryngeal postlexical processes, the native language seems to play the primary role even for highly competent learners, but markedness might be relevant too. The novel findings of this study are that phonetic category formation seems to be easier than the acquisition of dynamic allophonic alternations and that metaphonological awareness is correlated with perception but not with production.

Research into L3 phonological acquisition has grown in the past decade, yet perceptual studies remain scarce. Existing studies report complex interactions between the phonetic categories of multilinguals’ L1, L2 and L3, depending on investigated feature and stage of L3 learning. This small-scale study, grounded in Complex Dynamic Systems Theory, examines the development of coda obstruent perception in seven beginner learners of Polish as an L3 (aged 21–39), with German as their L1 and English as their L2. Over ten months of instructed L3 learning, participants were tested four times using a timed forced-choice goodness task in both L2 and L3. Additionally, three participants provided monthly data between the second and fourth testing. Analyses across the sample revealed a competitive relationship between L2 and L3 perception, with L2 accuracy declining as L3 accuracy improved. Individual data, however, indicated more varied patterns: while one learner followed the overall trend, another exhibited decreasing accuracy in both their L2 and L3, and the third maintained accurate L2 perception alongside more accurate yet increasingly variable L3 perception. These findings highlight the value of analyzing both overall trends and individual data to better understand multilingual speech perception development, and suggest that, with growing L3 experience, the newly learnt L3 may influence L2 perception of a phonological process shared in the L1 and marked in the L2.

Pedagogical translanguaging (PTL) refers to the use of educational techniques that incorporate learners’ entire linguistic repertoire. Recent studies indicate that PTL is efficient in the teaching of morphological awareness to bilingual children. The question remains whether it can be successfully applied in the highly specific context of adult forced migrants’ classrooms. This study describes a new protocol developed within the framework of PTL to teach derivational morphology to L2 French and Greek adults. We used questionnaires to quantitatively and qualitatively assess the feasibility of the protocol, teachers’ and learners’ attitudes, and learners’ emotions in the PTL lesson. A total of 141 migrant learners (79 forced migrants) and 13 teachers were involved in 23 2 h lessons. Teachers and learners gave high overall evaluations of the feasibility of the PTL protocol and of their pleasure from teaching and learning using PTL tools. Learners’ ease of learning and learning benefits were positively influenced by their perception of the proximity between their L1 and L2. Learners reported higher positive emotions and lower negative emotions during the PTL lesson, while forced migrants showed more hope and shame overall than voluntary migrants, as well as gained more benefits from PTL due to enjoyment. These findings suggest that the use of pedagogical translanguaging in migrants’ classrooms is feasible and develops positive attitudes and emotions, which are more pronounced in forced migrants.

Humans segment speech naturally based on the transitional probabilities between linguistic elements. For bilingual speakers navigating between a first (L1) and a second language (L2), L1 knowledge can influence their perception, leading to transfer effects based on phonological similarities or differences. Specifically, in Spanish, resyllabification occurs when consonants at the end of a syllable or word boundary are repositioned as the onset of the subsequent syllable. While the process can lead to ambiguities in perception, current academic discussions debate the duration of canonical and resyllabified productions. However, the role of bilingualism in the visual perception of syllable and word segmentation remains unknown to date. The present study explores the use of bilingual skills in the perception of articulatory movements and visual cues in speech perception, addressing the gap in the literature regarding the visibility of syllable pauses in lipreading. The participants in this study, 80 native Spanish speakers and 195 L2 learners, were subjected to audio, visual-only, and audiovisual conditions to assess their segmentation accuracy. The results indicated that both groups could segment speech effectively, with audiovisual cues providing the most significant benefit. Native speakers performed more consistently, while proficiency influenced L2 learners’ accuracy. The results show that aural syllabic segmentation is acquired at early stages of proficiency, while visual syllabic segmentation is acquired at higher levels of proficiency. Full article

Pronunciation is crucial to L2 learning. However, achieving speech proficiency is difficult. Class time constraints make demonstration–imitation pronunciation teaching methods less effective, even after repeated practice. Research suggests that pronunciation involves motor control, that auditory preparation enhances accuracy, and that learners produce more accurate pronunciation after perceiving accurate target sounds. This study proposes that the perception of accurate L2 target sounds will enhance pronunciation. To test this concept, the study employed online auditory training tasks for English learners enrolled at a private university in Taiwan. The results showed that auditory teaching results in positive learning outcomes. Full article

The communicative approach to language learning, a teaching method commonly used in second language (L2) classrooms, places little to no emphasis on pronunciation training. As a result, mobile-assisted pronunciation training (MAPT) platforms provide an alternative to classroom-based pronunciation training. To date, there have been several meta-analyses and systematic reviews of mobile-assisted language learning (MALL) studies, but only a few of these meta-analyses have concentrated on pronunciation. To better understand MAPT’s impact on L2 learners’ perceptions and production of targeted pronunciation features, this study conducted a systematic review of the MAPT literature following PRISMA 2020 guidelines. Potential mobile-assisted articles were identified through searches of the ERIC, Educational Full Text, Linguistics and Language Behavior Abstract, MLI International, and Scopus databases and specific journal searches. Criteria for article inclusion in this study included the following: the article must be a peer-reviewed empirical or quasi-empirical research study using both experimental and control groups to assess the impact of pronunciation training. Pronunciation training must have been conducted via MALL or MAPT technologies, and the studies must have been published between 2014 and 2024. A total of 232 papers were identified; however, only ten articles with a total of 524 participants met the established criteria. Data pertaining to the participants used in the study (nationality and education level), the MPAT applications and platforms used, the pronunciation features targeted, the concentration on perception and/or production of these features, and the methods used for training and assessments were collected and discussed. Effect sizes using Cohen’s d were also calculated for each study. The findings of this review reveal that only two of the articles assessed the impact of MAPT on L2 learners’ perceptions of targeted features, with results indicating that the use of MPAT did not significantly improve L2 learners’ abilities to perceive segmental features. In terms of production, all ten articles assessed MPAT’s impact on L2 learners’ production of the targeted features. The results of these assessments varied greatly, with some studies indicating a significant and large effect of MAPT and others citing non-significant gains and negligible effect sizes. The variation in these results, in addition to differences in the types of participants, the targeted pronunciation features, and MAPT apps and platforms used, makes it difficult to conclude that MAPT has a significant impact on L2 learners’ production. Furthermore, the selected studies’ concentration on mostly segmental features (i.e., phoneme and word pronunciation) is likely to have had only a limited impact on participants’ intelligibility. This paper provides suggestions for further MAPT research, including increased emphasis on suprasegmental features and perception assessments, to further our understanding of the effectiveness of MAPT for pronunciation training.

In applied linguistics, there has been a growing body of L2 pragmatics studies that investigate the intricate relationship between language learners’ subjective pragmatic choices and various contextual factors. The current study contributes to the understanding of language learner agency by illustrating the complex processes through which language learners enact their agency in response to varying contextual factors when making their sociopragmatic interpretations and strategies. To capture the ecological nature of agency, this study conceptualizes agency as contextually, interpersonally, intrapersonally, spatially, and temporally embedded. Through the in-depth examination of the accounts of three L2 learners of Japanese regarding their interactions with religious group members during their study abroad in Japan, this study demonstrates language learners’ divergent ways of enacting their agency, stemming from their orientations to the unique configurations of various contextual attributes in the L2 interactions. Such differences were rooted in and guided by their past experiences, present environments, and future aspirations that impacted their sociopragmatic perceptions, expectations, and choices. This study provides a complicated picture of language learner agency as a dialogic and reflexive process in which learners interact with contextual factors and adapt their sociopragmatic choices. Thus, it calls for an ecological, processual, and holistic approach to language learner agency through the close examination of the ways in which various contextual factors come together in L2 interactions, the process of how language learners orient to dynamic configurations of contextual factors, and what guides such orientations.
