Tube Talker Basic Demonstration

TubeTalker Description

TubeTalker is a moniker for the area function model described in: Story, B.H., (2005). A parametric model of the vocal tract area function for vowel and consonant simulation, J. Acoust. Soc. Am., 117(5), 3231-3254. The model is more recently described in Story, B.H., (2011), Proceedings of the International Workshop on Performative Speech and Singing Synthesis March 14-15, 2011, Vancouver, BC.

The purpose of developing this type of speech synthesizer is to provide a tool that can be used to facilitate understanding human production of speech and singing. The intent is not necessarily to produce a synthetic speaker for purposes of text-to-speech systems or other speech technology applications. Nonetheless, our goal is to advance this model such that it produces high-quality, intelligible speech.

The audio demonstrations on this website were produced with TubeTalker coupled to a digital waveguide model of the vocal tract. The voice source is a kinematic model of the 3D glottis based on Titze (2006), The myoelasticaerodynamic theory of phonation, NCVS, pp. 197-214. The basic system of wave propagation is described in my dissertation.

A more complete explanation and additional demos of TubeTalker are available in Story (2013), Phrase-level speech simulation with an airway modulation model of speech production, Computer Speech and Language.The article can be accessed here Click on this link for audio samples that coincide with this paper.

The movies below are similar to those included with the article, except that these contain a synchronized audio track. In each case, the vocal tract is shown in a pseudo-midsagittal configuration. That is, the shape of the airway extending from just above the vocal folds to lips is shown along a curve based on anatomical considerations, but no anatomical structures are indicated.
