This dissertation examines the associations between pragmatic meaning categories in English and specific realizations of prosodic prominence. It has been well-established that in Mainstream American English (MAE), prominence is often used to convey contrast. A more limited set of studies suggests that prosodic prominence may also be capable of…

Previous studies reported mixed findings on autistic individuals' pitch perception relative to neurotypical (NT) individuals. We investigated whether this may be partly due to individual differences in cognitive abilities by comparing their performance on various pitch perception tasks on a large sample (n = 164) of autistic and NT children and…

Purpose: "Dynamic pitch," which is defined as the variation in fundamental frequency in speech, is one of the acoustic cues that affect speech recognition in noise. Built on the evidence that a symmetrical manipulation of dynamic pitch led to poorer speech recognition, the present study examined the effect of an asymmetrical manipulation…

Purpose: Congenital amusia is a neurogenetic disorder of musical pitch processing. Its linguistic consequences have been examined separately for speech intonations and lexical tones. However, in a tonal language such as Chinese, the processing of intonations and lexical tones interacts with each other during online speech perception. Whether and…

Purpose: This study examined spontaneous, spoken-to-a-model, and two sung modes in speakers with Parkinson's disease (PD), speakers with cerebellar disease (CD), and healthy controls. Vocal performance was measured by intelligibility scores and listeners' perceptual ratings. Method: Participants included speakers with hypokinetic dysarthria…

Purpose: This study builds upon an established effective training method to investigate the advantages of high variability phonetic identification training for enhancing lexical tone perception and production in Mandarin-speaking pediatric cochlear implant (CI) recipients, who typically face ongoing challenges in these areas. Method: Thirty-two…

Background and aims: Fascinations for or aversions to particular sounds are a familiar feature of autism, as is an ability to reproduce another person's utterances, precisely copying the other person's prosody as well as their words. Such observations seem to indicate not only that autistic people can pay close attention to what they hear, but…

Purpose: This article aimed at investigating the neural underpinnings of music-to-language transfer effects at the pre-attentive level of processing. Method: We conducted a longitudinal experiment with a test-training-retest procedure. Non-musician adults were trained either on frequency (experimental group) or on intensity (control group) of…

Using a semi-spontaneous speech corpus, we present evidence from computational modelling of tonal productions from Mandarin-speaking children (4- to 11-years old) and adults, showing that children exceed the adult-level tonal distinction at the age of 7 to 8 years using F0 cues, but do not reach the high adult-level distinction using spectral cues…

Purpose: Maturation of the ability to recognize target speech in the presence of a two-talker speech masker extends into early adolescence. This study evaluated whether children benefit from differences in fundamental frequency (f[subscript o]) contour depth between the target and masker speech, a cue that has been shown to improve recognition in…

Efficient neural encoding of sound plays a critical role in speech and language, and when impaired, may have reverberating effects on communication skills. This study investigated disruptions to neural processing of temporal and spectral properties of speech in individuals with ASD and their parents and found evidence of inefficient temporal…

Purpose: Congenital deafness not only delays auditory development but also hampers the ability to perceive nonspeech and speech signals. This study aimed to use auditory event-related potentials to explore the mismatch negativity (MMN), P3a, negative wave (Nc), and late discriminative negativity (LDN) components in children with and without…

Purpose: This study aims to investigate the different degeneration processes of categorical perception (CP) of Mandarin lexical tones in the normal aging population and the pathological aging population with mild cognitive impairment (MCI). Method: In Experiment I, we compared the identification and discrimination of Tone 1 and Tone 2 across young…

The present study seeks to determine whether superior musical hearing is correlated with successful production of second language (L2) intonation patterns. Fifty Polish speakers of English at the university level were recorded before and after an extensive two-semester accent training course in English. Participants were asked to read aloud a…

Fetal hearing experiences shape the linguistic and musical preferences of neonates. From the very first moment after birth, newborns prefer their native language, recognize their mother's voice, and show a greater responsiveness to lullabies presented during pregnancy. Yet, the neural underpinnings of this experience inducing plasticity have…
