Modeling natural sounding voice qualities – for example the pressed-modalbreathy voice quality continuum which widely occurs during normal speech production – is a crucial point in speech synthesis. A parametric voice source model using prescribed sinusoidal vocal fold vibration patterns (i.e. extended Titze model) is introduced in this paper. This voice source model was adapted for synthesis o...

Given the importance of voice quality in signalling personal identity and social group membership, effective control of voice features may become especially important during adolescence, yet this has to be achieved in the context of significant physical changes within the speech production system. Most previous research has focussed on phonation, but this study used Vocal Profile Analysis (VPA)...

background : a head and neck (h&n;) cancer severely affect the voice and compromises the patient’s vocal independence. the present study proposed to investigate the difference in the three vital components of voice the pitch, jitter and shimmer in h&n; cancer patients and compared it with age matched healthy volunteers. methods : the voice parameters were ascertained in the freshly diagnosed h&...

Spoken words have robust acoustic variation. How listeners understand spoken words despite this variation remains an issue central to theories of speech perception. Current models predict listener behavior based on the frequency of a variant in production. A phonological variant, though, is often investigated independent of phonetic variation that provides listeners with information about talke...

Voice disguise by impersonation is often used in voice-based crimes by perpetrators who try to evade identification while sounding genuine. Voice evidence from these crimes is analyzed to both detect impersonation, and match the impersonated voice to the natural voice of the speaker to prove its correct ownership. There are interesting situations, however, where a speaker might be confronted wi...

Voice production involves precise, coordinated movements of the intrinsic and extrinsic laryngeal musculature. A component of normal voice production is the modification of pitch. The underlying neural networks associated with these complex processes remains poorly characterized. However, several investigators are currently utilizing neuroimaging techniques to more clearly delineate these netwo...

Behavioral syntactic priming effects during sentence comprehension are typically observed only if both the syntactic structure and lexical head are repeated. In contrast, during production syntactic priming occurs with structure repetition alone, but the effect is boosted by repetition of the lexical head. We used fMRI to investigate the neuronal correlates of syntactic priming and lexical boos...

OBJECTIVE The goal of the study is to use physical modelling of voice production to assess the performance of an inverse filtering method in estimating the glottal flow from acoustic speech pressure signals. METHODS An automatic inverse filtering method is presented, and speech pressure signals are generated using physical modelling of voice production so as to obtain test vowels with a known...

6 An analytical study of cepstral peak prominence (CPP) is presented, intended to provide an insight into its meaning and relation with voice perturbation parameters. To carry out this analysis, a parametric approach is adopted in which voice production is modelled using the traditional source-filter model and the first cepstral peak is assumed to have Gaussian shape. It is concluded that the m...
