Previous research of laryngeal-oral gestural coordination in vowel-voiceless fricative sequences (Vf) shows that earlier timing of glottal opening relative to oral constriction is a languageindependent aerodynamic property. In this paper, we provide evidence that the extent of this gestural dissociation is nonetheless learnable in a varietyspecific way, and is, thus, actively controlled. This s...

Phonetic variation in the realization of segments is increasingly recognized to have functional value in signalling matters such as constituency, but patterns of variation of rarer segment types are not as well known as those of common types such as plosives. This paper presents data on variation in production of glottalized sonorants in the Austronesian language Yapese. Initial glottalized son...

This paper studies the use of glottal inverse filtering together with a biomechanical model of the vocal folds to simulate the glottal flow waveform. The glottal flow waveform is first estimated by inverse filtering the acoustic speech pressure signal of natural speech. The estimated glottal flow is used as a template in an optimization process which searches for a set of parameters for a deter...

BACKGROUND effectiveness of the sonorous tongue vibration technique (STVT). AIM to investigate the sensations and the vocal and laryngeal impact produced by the sonorous tongue vibration technique. METHOD The STVT was performed in three sets of fifteen repetitions, in maximum phonatory duration using a normal tone and intensity - with 30 seconds intervals of passive rest between each set. T...

A structural magnetic resonance imaging study has revealed that pharyngeal articulation varies considerably with voicing during the production of English fricatives. In a study of four speakers of American English, pharyngeal volume was generally found to be greater during the production of sustained voiced fricatives, compared to voiceless equivalents. Though pharyngeal expansion is expected f...

The representation of the glottal source is of paramount importance for describing para-linguistic information carried through the voice quality (e.g., emotions, mood, attitude). However, some existing representations of the glottal source are based on analytical glottal models, which assume strong a priori constraints on the shape of the glottal pulses. Thus, these representations are restrict...

Inverse filtering of oral airflow using closed-phase linear prediction is expected to preserve the effects of source-filter interactions in the glottal airflow pulse. Under incomplete glottal closure, the glottal airflow estimation is more challenging due to a lowered glottal impedance, increased subglottal coupling, and violated all-pole assumption. To account for these effects, a model-based ...

Background: effectiveness of the sonorous tongue vibration technique (STVT). Aim: to investigate the sensations and the vocal and laryngeal impact produced by the sonorous tongue vibration technique. Method: The STVT was performed in three sets of fifteen repetitions, in maximum phonatory duration using a normal tone and intensity with 30 seconds intervals of passive rest between each set.

The quantitative relationship between glottal flow parameters (fundamental frequency, average flow, peak flow etc.) and glottal control parameters (cord tension, glottal adduction, subglottal pressure) has been measured. Using the condition of constant glottal flow our model is able to produce the range of pitches of the modal tenor register. Increasing fundamental frequency is realized by incr...

This paper deals with the modelling of glottal stop for the purposes of Czech text-to-speech synthesis. Phonetic features of glottal stop are discussed here and a phonetic transcription rule for inserting glottal stop into the sequences of Czech phones is proposed. Two approaches to glottal stop modelling are introduced in the paper. The first one uses glottal stop as a stand-alone phone. The s...
