There is a long-standing debate in the literature about the benefits that acoustic components of Infant Directed Speech (IDS) might have for infants' language acquisition. One of the highly contested features is vowel space expansion, which refers to the enlargement of the acoustic space between the corner vowels /i, u, a/ in IDS compared to Adult…

High-Variability Phonetic Training (HVPT) has demonstrated effectiveness in second language (L2) acquisition. This study utilizes a meta-analysis to explore the influence of high variability on learning L2 pronunciation and identifies the factors that moderate this impact. The studies were collected using a keyword search in the SCOPUS database.…

This article discusses the implications of phonological representation for the study of L2 speech acquisition. It is argued, on the basis of empirical findings from diverse phenomena in L2 phonology, that refined representations in which 'segments' have internal prosodic structure offer a more insightful view of cross-linguistic phonetic…

The functions of acoustic-phonetic modifications in infant-directed speech (IDS) remain a question: do they specifically serve to facilitate language learning via enhanced phonemic contrasts (the hyperarticulation hypothesis) or primarily to improve communication via prosodic exaggeration (the prosodic hypothesis)? The study of lexical tones…

Speech discourse is the communication between people, that is, the speaker seeks to influence the recipient in a conversation, using deep thoughts and meaningful words, expecting to receive a response from the addressee. In modern Kazakh linguistics, speech discourse is being explored in various ways as a reflection of people's relationships and…

Two acoustic studies of voice onset time (VOT) in sibilant-stop (ST) consonant clusters, produced by first language (L1) speakers of Polish, are presented. In the first, a baseline study of L1 Polish comparing ST clusters with initial singleton stops, a small degree of VOT shortening after /s/ was found for /p/, but not /t/. The second study…

In the present research we look into the mechanisms which facilitate integrated functioning of speech and music components within a song. To understand the underlying mechanisms of such interaction we investigate poems set to music, analyzing the components of both speech and music intonation. The study is performed within the scope of Speech…

Classic typologies within prosody tend to treat 'tone' languages as being diametrically opposed to 'stress' languages. However, Hyman (2006) highlights several languages that can have both, including Seneca, Fasu, and Copala Trique. As language documentation advances and our acoustic methodologies in the field are further refined, we have seen…

Gender differences are manifested not only in the physiological characteristics of a person, but also in the speech communication. This article presents the research data obtained at the phonetic and lexical levels of the language. The purpose of this work is to determine the speech characteristics that distinguish men and women at the studied…

Purpose: There is a lack of standardized Mandarin reading text material that could potentially elicit significant variations in fundamental frequency (F0) and in vocal intensity for clinical voice evaluation. In this study, a phonetically balanced "Three Bears Passage" was developed based on the classical "Goldilocks" story for…

Children are adept at learning their language's speech-sound categories, but just how these categories function in their developing lexicon has not been mapped out in detail. Here, we addressed whether, in a language-guided looking procedure, 2-year-olds would respond to a mispronunciation of the voicing of the initial consonant of a newly learned…

Cued Speech (CS) is a communication system developed for deaf people, which exploits hand cues to complement speechreading at the phonetic level. Currently, it is estimated that CS has been adapted to over 60 languages; however, no official CS system is available for Mandarin Chinese. This article proposes a novel and efficient Mandarin Chinese CS…

Vowel nasalization usually occurs through a two-step process whereby a vowel is nasalized via coarticulation with a nearby nasal segment; when the language later drops the nasal segment, a nasal vowel remains. Spontaneous vowel nasalization is a rare, peculiar form of nasalization that emerges in contexts that lack an historical etymological nasal…

Objective: We aimed to investigate the production of contrastive emphasis in French-speaking 4-year-olds and adults. Based on previous work, we predicted that, due to their immature motor control abilities, preschool-aged children would produce smaller articulatory differences between emphasized and neutral syllables than adults. Method: Ten…

This dissertation investigated the acoustic and articulatory correlates of lexical stress in Mandarin second language (L2) learners of English, as well as in first language (L1) speakers. The present study used a minimal pair respective to stress location (e.g., OBject versus obJECT) obtained from a publicly available Mandarin Accented English…
