Purpose: The purpose of the current study was to examine normative nasalance values in Vietnamese adult speakers with Southern dialect and to investigate the effects of vowels and tones on . Previous studies examining nasalance have been mainly conducted with Indo-European languages. Limited information on nasalance is available in tone languages…

Purpose: The purpose of this study was to examine the aging effects on the categorical perception (CP) of Mandarin lexical Tones 1-4 and Tones 1-2 in noise. It also investigated whether listeners' categorical tone perception in noise correlated with their general tone identification of 20 natural vowel-plus-tone signals in noise. Method: Twelve…

As the most commonly established and attested language contact phenomenon, loanwords, also known as lexical borrowings, may undergo transformations when borrowed from the source language (SL) to the borrowing language (BL). Previous studies have separately illustrated the role of perception and phonology in the borrowing process. However, the…

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…

Purpose: The aim of this study was to investigate children's acquisition of Vietnamese speech sounds. Method: Participants were 195 children aged 2;2-5;11 (years;months) living in Northern Viet Nam who spoke Vietnamese as their 1st language. Single-word samples were collected using the Vietnamese Speech Assessment (Ph?m, Le, & McLeod, 2016) to…

Purpose: This study examined the acoustic properties of Taiwanese (Southern Min) lexical tones produced in esophageal speech (ES) and pneumatic artificial laryngeal speech (PAL), including onset fundamental frequency (F0), slope of F0 contour, duration, and amplitude (intensity) of the vowel portion of syllables carrying seven Taiwanese tones.…

Purpose: Models of speech production often abstract away from shared physiology in pitch control and lingual articulation, positing independent control of tone and vowel units. We assess the validity of this assumption in Mandarin Chinese by evaluating the stability of lingual articulation for vowels across variation in tone. Method:…

Purpose: Natural speech comes with variation in pitch, which serves as an important cue for speech recognition. The present study investigated older listeners' dynamic pitch perception with a focus on interindividual variability. In particular, we asked whether some of the older listeners' inability to perceive dynamic pitch stems from the higher…

Purpose: The purpose of this study was to determine whether the degree of dominance of Mandarin-English bilinguals' languages affects phonetic processing of tone content in their native language, Mandarin. Method: We tested 72 Mandarin-English bilingual college students with a range of language-dominance profiles in the 2 languages and ages of…

Four eye movement experiments investigated whether readers use parafoveal input to gain information about the phonological or orthographic forms of consonants, vowels, and tones in word recognition when reading Thai silently. Target words were presented in sentences preceded by parafoveal previews in which consonant, vowel, or tone information was…

The present study investigated whether the neural correlates for auditory feedback control of vocal pitch can be shaped by tone language experience. Event-related potentials (P2/N1) were recorded from adult native speakers of Mandarin and Cantonese who heard their voice auditory feedback shifted in pitch by -50, -100, -200, or -500 cents when they…

Perceptual reorganisation of infants' speech perception has been found from 6 months for consonants and earlier for vowels. Recently, similar reorganisation has been found for lexical tone between 6 and 9 months of age. Given that there is a close relationship between vowels and tones, this study investigates whether the perceptual reorganisation…

The correlation between individual level tones and vowel duration in Standard Thai was investigated. The study was prompted by the discrepancy between Gandour's 1977 claim that the pitch value of the three relatively level tones in Thai is negatively correlated with vowel duration and Roberson's 1982 disagreement with this hypothesis. The result…

We present an acoustic study of segmental and prosodic properties of words produced by a female speaker of Chinese with left-hemisphere brain damage. We measured the location of the point vowels /a, e, @?, i, y, o, u/ and determined their separation in the vowel plane, and their perceptual distinctivity. Similarly, the acoustic properties of the…

Reports the results of three experiments that used vowel and tone monitoring tasks to investigate the role of tone information in processing Mandarin. (Author/VWL)
