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: Previous studies have shown that individuals with congenital amusia exhibit deficient pitch processing across music and language domains. This study investigated whether adult Chinese-speaking listeners with amusia were still able to learn Thai lexical tones based on stimulus frequency of statistical distribution via distributional…

The purpose of this study was to examine the effects of timbral instructions on pitch and timbre production. High school (n = 28) and collegiate (n = 28) trumpeters played sustained tones at two octave levels (written C4 and C5) following three types of timbral instructions (dark-timbre, bright-timbre, or neutral instructions). Presentation orders…

Purpose: This study aimed to examine how aging and modifications of critical acoustic parameters may affect the perception of whispered speech as a degraded signal. Method: Forty Mandarin-speaking adults were included in the study. Part 1 of the study compared the perception of Mandarin lexical tones, vowels, and syllables in older and younger…

Purpose: Previous studies have demonstrated that tone identification can be facilitated when auditory tones are integrated with visual information that depicts the pitch contours of the auditory tones (hereafter, visual effect). This study investigates this visual effect in combined visual-auditory integration with high- and low-variability speech…

Research on language learners' attention suggests that manipulating attention is beneficial in the language learning process as it facilitates the "noticing" of specific linguistic aspects. The current study investigated the effects of directing learners' attention to segments and prosody in English phonetic training. Korean learners of…

Purpose: This study investigated the categorical perception of Mandarin tones and consonant aspiration contrasts in babble noise among adults and adolescents aged 12-14 years, and explored the association between working memory and categorical perception. Method: Twenty-four adults and 20 adolescents with Mandarin as their native language were…

This study investigated how Korean toddlers' perception of stop categories develops in the acoustic dimensions of VOT and F0. To examine the developmental trajectory of VOT and F0 in toddlers' perceptual space, a perceptual identification test with natural and synthesized sound stimuli was conducted with 58 Korean monolingual children (aged 2-4…

Purpose: Vocal roughness is often present in many voice disorders but the assessment of roughness mainly depends on the subjective auditory-perceptual evaluation and lacks acoustic correlates. This study aimed to apply the concept of roughness in general sound quality perception to vocal roughness assessment and to characterize the relationship…

This research investigated whether observing beat gesture and hearing contrastive accenting with novel words enhances their learning in early childhood and whether these effects differ by sex in light of sex differences in the pace of language development. Fifty-three 3- to 5-year-old boys and girls learned pairs of novel words with contrasting…

The current study examined the phonolexical processing of Mandarin segments and tones by English speakers at different Mandarin proficiency levels. Eleven English speakers naive to Mandarin, 15 intermediate and 9 advanced second language (L2) learners participated in a word-learning experiment. After learning the sound and meaning of 16 Mandarin…

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: Humans have a near-automatic tendency to entrain their motor actions to rhythms in the environment. Entrainment has been hypothesized to play an important role in processing naturalistic stimuli, such as speech and music, which have intrinsically rhythmic properties. Here, we studied two facets of entraining one's rhythmic motor actions…

Purpose: This research compared individuals from two first language (L1) backgrounds (English and Japanese) to determine how they may differ in their perception of Mandarin tones (Tones 1 vs. 2 [T1-T2], Tones 1 vs. 3 [T1-T3], Tones 1 vs. 4 [T1-T4], Tones 2 vs. 3 [T2-T3], Tones 2 vs. 4 [T2-T4], Tones 3 vs. 4 [T3-T4]) on account of their L1. Method:…

This study examines whether Japanese native (L1) listeners can implicitly learn stress pattern regularities, not present in their L1, after a brief auditory exposure. In the exposure phase, the participants listened to and repeated words bearing stress patterned after Latin, but with a highly restricted consonant inventory. They performed a…
