This study investigates the perception and production of a specific type of metaphoric gesture that mimics melody in speech, also called pitch gesture, in the learning of L2 suprasegmental features. In a between-subjects design, a total of 106 participants with no previous knowledge of Chinese were asked to observe (Experiment 1) and produce (Experiment 2) pitch gestures during a short multimodal training session on Chinese tones and words. In both experiments they were tested on (a) tone identification and (b) word learning. Results showed the positive effect of a training session with pitch gesture observation compared to a training session without it (Experiment 1) and the benefits of producing gestures compared to only observing them and repeating the words aloud (Experiment 2). A comparison of the results of the two experiments revealed that there was no significant difference between the simple observation of pitch gestures and the production of speech accompanied by pitch gestures in facilitating lexical tone identification and word learning. Thus, both perception and production tasks with pitch gestures can be regarded as beneficial learning strategies for the initial stages of tones acquisition in the Chinese as a Second Language classroom.

Though research has shown that rhythmic training is beneficial for phonological speech processing, little empirical work has been carried out to assess whether rhythmic training in the classroom can help to improve pronunciation in a second language. This study tests the potential benefits of hand-clapping to the rhythm of newly learned French words for the acquisition of pronunciation patterns by Chinese adolescents. In a between-subjects training experiment with a pretest/posttest design, 50 Chinese adolescents either repeated new French words while clapping out their rhythmic structure (clapping condition) or only repeated the words (non-clapping condition). Participants’ oral production before and after training was (1) perceptually rated for accentedness by two French native speakers and (2) acoustically analysed for final syllable duration. While the results showed an only near-significant improvement from pretest to posttest in accentedness ratings for the clapping group, a significant improvement was obtained for acoustic durational measures. Individual musical abilities did not interact significantly in either of the two analyses, and working memory interacted significantly only with accentedness. These results show that a short training session in which clapping is used to highlight the prosodic structure of words can help improve pronunciation in a foreign language.

Recent studies on the learning of L2 prosody have suggested that pitch gestures can enhance the learning of the L2 lexical tones. Yet it remains unclear whether the use of these gestures can aid the learning of L2 intonation, especially by tonal-language speakers. Sixty-four Mandarin speakers with basic-level Spanish were asked to learn three Spanish intonation patterns, all involving a low tone on the nuclear accent. In a pre-post test experimental design, half of the participants received intonation training without the use of pitch gestures (the control group) while the other half received the same training but with pitch gestures representing nuclear intonation contours (the experimental group). Musical (melody, pitch) abilities were also measured. The results revealed that (a) the experimental group significantly improved intonational production outcomes, and (b) even though participants with stronger musical abilities performed better, those with weaker musical abilities benefited more from observing pitch gestures.

While empirical studies have shown the beneficial role of observing and producing hand gestures mimicking pitch features in the learning of L2 tonal or intonational contrasts, mixed results have been obtained for the use of gestures encoding durational contrasts at the perceptual level. This study investigates the potential benefits of horizontal hand-sweep gestures encoding durational features for boosting the perception and production of nonnative vowel-length contrasts. In a between-subjects experiment with a pretest–posttest design, 50 Catalan participants without any knowledge of Japanese practiced perceiving and producing minimal pairs of Japanese disyllabic words featuring vowel-length contrasts in one of two conditions, namely with gestures or without them. Pretest and posttest consisted of the completion of identical vowel-length identification and imitation tasks. The results showed that while participants improved equally at posttest across the two conditions in the identification task, the Gesture group obtained a larger improvement than the No Gesture group in the imitation task. These results corroborate the claim that producing hand gestures encoding prosodic properties of speech may help naïve learners to learn novel phonological contrasts in a foreign language.

Previous research has shown that rhythmic training enhances phonological speech processing (e.g., [1,2,3,4]). Yet little is known about whether rhythmic training can also help to improve pronunciation in a second language (but see [5,6,7]). This study tests the potential benefits of hand-clapping to the rhythm of newly learned French words for the acquisition of pronunciation patterns by Catalan children and Chinese adolescents. In two between-subjects experiments with a pretest and posttest design, participants either repeated words while clapping the rhythmic structure of words or only repeated the words. The French target words were very similar to their lexical counterparts in Catalan, whereas they differed completely from Chinese. Participants' oral production before and after training was rated for accentedness by three French native speakers. Results showed a significant improvement for the clapping group among the Catalan participants, whereas only a near significant tendency appeared for the Chinese adolescents. Individual musical abilities did not interact significantly with the results in either experiments but working memory played a significant role in Chinese participants' pronunciation. The results show that a short phonological training session based on highlighting the rhythmic structure of words seems to help improve pronunciation in a foreign language as long as there is little demand placed on semantic processing.

Purpose Research has shown that observing hand gestures mimicking pitch movements or rhythmic patterns can improve the learning of second language (L2) suprasegmental features. However, less is known about the effects of hand gestures on the learning of novel phonemic contrasts. This study examines (a) whether hand gestures mimicking phonetic features can boost L2 segment learning by naive learners and (b) whether a mismatch between the hand gesture form and the target phonetic feature influences the learning effect. Method Fifty Catalan native speakers undertook a short multimodal training session on two types of Mandarin Chinese consonants (plosives and affricates) in either of two conditions: Gesture and No Gesture. In the Gesture condition, a fist-to-open-hand gesture was used to mimic air burst, while the No Gesture condition included no such use of gestures. Crucially, while the hand gesture appropriately mimicked the air burst produced in plosives, this was not the case for affricates. Before and after training, participants were tested on two tasks, namely, the identification task and the imitation task. Participants' speech output was rated by five Chinese native speakers. Results The perception results showed that training with or without gestures yielded similar degrees of improvement for the identification of aspiration contrasts. By contrast, the production results showed that, while training without gestures did not help improve L2 pronunciation, training with gestures improved pronunciation, but only when the given gestures appropriately mimicked the phonetic properties they represented. Conclusions Results revealed that the efficacy of observing hand gestures on the learning of nonnative phonemes depends on the appropriateness of the form of those gestures relative to the target phonetic features. That is, hand gestures seem to be more useful when they appropriately mimic phonetic features. Supplemental Material https://doi.org/10.23641/asha.13105442

The present study explored whether listening to songs and singing can improve second language pronunciation and vocabulary learning at beginning stages of language acquisition. One hundred and eight Chinese students underwent a 4-min training session to learn 14 words from a meaningful French song about the parts of the body in either one of two conditions: in Experiment 1, listening to rhythmic speech vs listening to the same words but in a song (50 participants), and in Experiment 2, listening to vs singing a song (58 participants). Accentedness ratings of pretest and posttest recordings revealed that (a) the song listening group reduced accentedness significantly more than the rhythmic speech listening group (Experiment 1); and (b) singing and listening to a song yielded similar significant improvements after training (Experiment 2).
