Background: Children with phonological impairment present with pattern-based errors in their speech production. While some children have difficulties with speech perception and/or the establishment of robust underlying phonological representations, the nature of phonological impairment in children is still not well understood. Given that…

Purpose: ?he lexical stress pattern (trochaic vs. iambic) may affect various aspects of word learning and word production in children with cochlear implants (CIs). This study aimed to investigate lexical stress effects in word learning by Greek-speaking children with CIs. Method: A word learning paradigm, consisting of a word production and a word…

Purpose: Individuals vary in their ability to learn the sound categories of nonnative languages (nonnative phonetic learning) and to adapt to systematic differences, such as accent or talker differences, in the sounds of their native language (native phonetic learning). Difficulties with both native and nonnative learning are well attested in…

The question of whether second languages (L2s) are best learned implicitly or explicitly has been a topic of much empirical discourse, with the majority of studies pointing to the benefits of explicit instruction when learning L2 grammar rules. However, given the focus on grammar, it is unclear how generalizable these findings are to other…

This dissertation presents three studies that examined issues related to the production and the perception of pitch in a tone language. The first study examined linguistic contexts that may modulate consonant-induced pitch perturbations (CF0) in a tone language. Previous studies have produced mixed findings regarding the role of linguistic…

Purpose: This study compared perception of consonants in medial position by preschoolers, with and without speech sound disorder (SSD), with similar vocabulary and language skills. In addition, we investigated the association between speech perception and production skills. Method: Participants were 36 monolingual English-speaking children with…

Previous research has shown that an increased second language (L2) vocabulary size leads to better attunement to the cues required to distinguish L2 contrastive phones. This has been the central tenet of the vocabulary-tuning model (vocab) on the basis of evidence by Japanese learners of English in Australia. We aim to test the validity of the…

In conversational speech, it is very common for words' segments to be reduced or deleted. However, previous research has consistently shown that during spoken word recognition, listeners prefer words' canonical pronunciation over their reduced pronunciations (e.g., pretty pronounced [word omitted] vs. [word omitted]), even when the latter are far…

Purpose: The purpose of this study was to compare masked English speech recognition thresholds between Spanish-English bilingual and English monolingual children and to evaluate effects of age, maternal education, and English receptive language abilities on individual differences in masked speech recognition. Method: Forty-three Spanish-English…

Visual information influences speech perception in both infants and adults. It is still unknown whether lexical representations are multisensory. To address this question, we exposed 18-month-old infants (n = 32) and adults (n = 32) to new word-object pairings: Participants either heard the acoustic form of the words or saw the talking face in…

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…

Background: Children with unilateral cochlear implants (CIs) may have delayed vocabulary development for an extended period after implantation. Bilateral cochlear implantation is reported to be associated with improved sound localization and enhanced speech perception in noise. This study proposed that bilateral implantation might also promote…

Whilst enhanced perception has been widely reported in individuals with Autism Spectrum Disorders (ASDs), relatively little is known about the developmental trajectory and impact of atypical auditory processing on speech perception in intellectually high-functioning adults with ASD. This paper presents data on perception of complex tones and…

Watching foreign language programmes and films with captions (same-language subtitles intended for the deaf and hard-of-hearing) has been shown to assist learners in phonetic retuning, vocabulary acquisition and listening comprehension [e.g. Mitterer and McQueen, 2009. Foreign subtitles help but native-language subtitles harm foreign speech…

Discusses (1) the process of early language development, giving specific attention to problematic aspects of a vocabulary for audition; (2) elicitation and instruction tasks used in the study of language acquisition; and (3) an investigation designed to compare language acquisition for dimensions of visual, spatial, and tactual perception with…
