BACKGROUND Pompe disease is a progressive metabolic myopathy. Disease progression is characterized, among other features, by progressive dysfunction of the voice apparatus. The aim of this study was to employ electroglottographic, acoustic and nasalance measurement methods on patients with late-onset Pompe disease in order to provide detailed information on the effect of the disease on voice qu...

The phenomenon of aspiration in Hindi has intrigued phoneticians and phonologists for some time. However, so far no adequate investigation of this phenomena has been made. The earlier acoustical (i.e., perceptional) studies which have been performed on the phonetic aspects of Hindi can be grouped into two 1) acoustically-oriented, and 2) linguistically-oriented studies. In the area of acoustic ...

OBJECTIVES Speech intelligibility is severely affected in children with congenital profound hearing loss. Hypernasality is a problem commonly encountered in their speech. Auditory information received from cochlear implants is expected to be far superior to that from hearing aids. Our study aimed at comparing the percentages of nasality in the speech of the cochlear implantees with hearing aid ...

In this paper we study the effect of source changes, caused by vocal tract load, in perception of nasality. For that we have developed an articulatory speech synthesizer, including a comprehensive nasal tract model and an interactive glottal source model. Our main objective was to investigate to what extent is necessary, in systems aimed to produce high quality synthetic sounds, to include the ...

Acknowledgments: Many thanks to audiences at UC Irvine, and at a UCSC phonology lunch meeting, for much helpful commentary. Thanks especially to Ryan Bush, Junko Itô, Armin Mester, Nathan Sanders, Rachel Walker, and Moira Yip. 1 On the following see Saussure's Cours de linguistique générale, and for interpretation Wells (1957) and Anderson (1985). The usual caveats when one attributes views to ...

The contrast between nasal vowels and oral vowels is phonemic in Taiwanese, however, their distributions are not entirely contrastive. For example, nasal nuclei do not occur when the coda is a nasal. It is analyzed that historically the nasal feature of the nasal coda spreads leftward to the nucleus, when the vocalic nasalization is rephonologized, the nasal coda is lost. Therefore, it has been...
