Previous research has found that a speaker's native phonological system has a great influence on perception of another language. In three experiments, we tested the perception and representation of Mandarin phonological contrasts by Guangzhou Cantonese speakers, and compared their performance to that of native Mandarin speakers. Despite their rich…

The greatest difficulty in reading Arabic script for nonnatives has long been considered as the absence of short vowels, however there is more to be dealt with. While the correlation of 28 Arabic consonants pose no great difficulty in deciphering the script, the six vowel phonemes voiced only by three letters even with help of some relevant…

Background: In many languages a weakness in non-word repetition serves as a useful clinical marker of specific language impairment (SLI) in children. However, recent work in Italian has shown that the repetition of real words may also have clinical utility. For young typically developing Italian children, real word repetition is more predictive of…

Among the many ways in which sounds alternate in the world's languages, changes in the order of sounds (metathesis) are relatively rare. Mutsun, a Southern Costanoan language of California which was documented extensively before the death of its last speaker in 1930, displays three patterns of synchronic consonant-vowel (CV) metathesis. Two of…

In this study, segmental and prosodic aspects of word repetition and non-word repetition in typically developing children aged four to six years were investigated. Focus was on developmental differences, and on how tonal word accent and word length affect segment production accuracy. Prosodically controlled words and non-words were repeated by 44…

This article presents data from three production experiments investigating the prosodic means of encoding information structure in Akan, a tone language that belongs to the Kwa branch of the Niger-Congo family, spoken in Ghana. Information structure was elicited via context questions that put target words either in wide, informational, or…

Intra-word inconsistency in a child is perceived as an indicator of speech impairment. Because the speech of typically developing children is highly variable, the extent and nature of the inconsistency must be defined when used as a diagnostic marker of speech impairment (McLeod, S., & Hewett, S. R. (2008). Variability in the production of words…

It remains controversial whether children are able to process and integrate specific linguistic cues in their mental model to the same extent as adults. In the present study, a sentence continuation task was employed to determine how Italian speakers (4-, 5-, 6-year-olds and adults) interpret prosodic cues to decide which referent is more salient…

Every language has its own rhythm. Unlike many other languages in the world, English depends on the correct pronunciation of stressed and unstressed or weakened syllables recurring in the same phrase or sentence. Mastering the rhythm of English makes speaking more effective. Experiments have shown that we tend to hear speech as more rhythmical…

This dissertation investigates how boundary temporal and tonal events are coordinated to oral constrictions in Greek. Regarding the temporal events, most studies agree in that boundary lengthening is cumulative (i.e., larger the stronger the boundary) (e.g., Cho & Keating 2001, Tabain 2003b) and progressive (i.e., decreasing with distance from…

Itoman, one of the varieties spoken in the southern part of Okinawa Island, exhibits several tone patterns. Although the tone patterns of Itoman were examined in previous studies (Nakasone ms., Hattori 1959, Oshiro 1963, and Hirayama et al. 1966), they ended at the descriptive level, and no phonological accounts for the surface tone patterns were…

This study develops the hypothesis that the child-specific phenomenon of positional velar fronting can be modeled as the product of phonologically encoded articulatory limitations unique to immature speakers. Children have difficulty executing discrete tongue movements, preferring to move the tongue and jaw as a single unit. This predisposes the…

The current dissertation represents one of the first systematic studies of the distribution of speech errors within supralexical prosodic units. Four experiments were conducted to gain insight into the specific role of these units in speech planning and production. The first experiment focused on errors in adult English. These were found to be…

Research has shown that lexical tones, a suprasegmental feature, are processed by native speakers as linguistic elements just like other segmental information. Among the four tones of Mandarin Chinese, in particular, Tone 2 and Tone 3 are very similar in their pitch contour shapes and thus can be difficult to distinguish in native and nonnative…

A common feature of public speech in Catalan is the placement of prominence on lexically unstressed syllables ("emphatic stress"). This paper presents an acoustic study of radio speech data. Instances of emphatic stress were perceptually identified. Within-word comparison between vowels with emphatic stress and vowels with primary lexical stress…
