Speech errors associated with cleft palate are well established for English and several other Indo-European languages. Few articles describing the speech of Putonghua (standard Mandarin Chinese) speakers with cleft palate have been published in English language journals. Although methodological guidelines have been published for the perceptual speech(More)
PURPOSE To examine perceptually the realization of unaspirated affricates and voice onset time (VOT) features of /t/ in Mandarin-speaking children with repaired cleft palate, and to explore the difficulties associated with unaspirated affricate production from the perspective of the VOT of /t/. METHOD Twenty-three children with repaired cleft palate and(More)
SiO2 films were deposited on fused silica, silicon, glass, germanium, and sapphire substrates by an ion beam sputtering technique. The optical properties of SiO2 films on different substrates and interfacial layer properties between SiO2 films and different substrates were researched by the spectroscopic ellipsometry technique. The refractive indices of(More)
OBJECTIVE To compare the consonant production of Chinese-speaking cleft palate children with perceived hypernasal resonance (PHR) after palatoplasty and those with perceived normal resonance (PNR), and to assess the possible influence of language on articulation. SETTING Two hospital cleft lip and palate centers in mainland China. PARTICIPANTS(More)
OBJECTIVE To explore the spectral differences in frication noise between aspirated and unaspirated affricates in typical Putonghua (standard Mandarin Chinese) pre-adolescent speakers, and to compare the spectral characteristics of affricate production between speakers with repaired cleft palate and their non-cleft peers. PARTICIPANTS AND INTERVENTION(More)
PURPOSE The aim of the study was to examine the relationship between the spectral features and perceptual judgments of places of affricate in Putonghua (standard Mandarin Chinese), and to explore the possible contribution of different spectral moments on correct perception of place of articulation information by typical pre-adolescent speakers and those(More)
