Purpose: Talkers adapt their speech according to the demands of their listeners and the communicative context, enhancing the properties of the signal (pitch, intensity) and/or properties of the code (enhancement of phonemic contrasts). This study asked how mothers adapt their child-directed speech (CDS) in ways that might serve the immediate goals…

This study investigated the use of Artificial Intelligence (AI) models and signal detection processes to generate meaningful visual and ChatGPT-like narrative feedback on second language (L2) English intelligibility. To test the effects and perceptions of such techniques, three groups of learners (N = 90) received visual and narrative feedback…

Whereas many scholars have emphasized the relative importance of "comprehensibility" as an ecologically valid goal for L2 speech training, testing, and development, eliciting listeners' judgments is time-consuming. Following calls for research on more efficient L2 speech rating methods in applied linguistics, and growing attention toward…

This study examines the effect of native "vs." non-native prosody instruction on developing interpreter trainees' speech comprehensibility in English as a foreign language (EFL) using a pretest-posttest-delayed posttest design. Twenty-three groups of 28 interpreter trainees at a University in Iran (six different branches) took part in…

Face masks affect the transmission of speech and obscure facial cues. Here, we examine how this reduction in acoustic and facial information affects a listener's understanding of speech prosody. English sentence pairs that differed in their intonational (statement/question) and emotional (happy/sad) prosody were created. These pairs were recorded…

This study considers the performance of tone pronunciation and morpheme intelligibility by L2 Polish Mandarin learners. A mixed-effects ordinal regression model and Tukey's HSD multiple test were used to examine the start-point, end-point, of syllables as a means of assessing their intelligibility by L2 Polish learners regarding the tones with the…

When it comes to paying attention to the suprasegmental features of their speech, most learners of English seem to be unaware that such phenomena as stress, pitch, duration, and pausing can be of great importance regarding mutual intelligibility. Since they carry a considerable weight of establishing an intelligible conversation, it is argued that…

Pronunciation teaching of the segmental aspects needs to be balanced with the inclusion of learner awareness of stress, rhythm, intonation and meaningful production. Yet many formats for pronunciation teaching do not place these skills and an awareness of the suprasegmental features in either a communicative format or a specific speaking…
