TubeTalker Demonstration
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 following are demonstrations of some of the speech sounds
produced with TubeTalker coupled to a digital
waveguide model of the vocal tract and a glottal area function type model for
the voice source.
Slide Show from XV

Audio and video
demos from ICVPB 2008 conference
in Tampere, Finland 08.09.08
These
demos are based on the same TubeTalker model for
changing the vocal tract shape. The voice source is a kinetic model of the 3D
glottis based on Titze (2006), The myoelastic
aerodynamic theory of phonation, NCVS, pp. 197-214.
Animation
of kinematic model of the 3D glottis:
1. Adductory maneuvers
without vibration
2. Adductory maneuvers
with vibration
Adductory Glides:
Building
the sentence He had a rabbit and a boat.
Audio
1. Vowel sequence + pitch changes
2. Vowel sequence + pitch changes + adductory changes
3. Consonant articulation + #2 (complete sentence)
6. Complete sentence but with breathy voice.
7. Complete sentence but with laryngeal tremor.
8. Complete sentence with lengthened vocal tract
and wide epilarynx
9. Complete sentence with lengthened vocal
tract and constricted epilarynx
10. First attempt at singing the sentence
11. Second attempt at singing the sentence.
12. Another attempt at singing - but one consonant is
changed. Which one?
Animations (note: so that
vocal tract shape changes can be easily observed, these run about 2.5 times
slower than real time)
1. Vowel sequence for the sentence -
tubular representation and formant tracks
2. Complete sentence: vowel sequence +
consonants (tubular representation and formant tracks)
3. Complete sentence: tubular representation with 3D
view
4. Complete sentence: tubular representation in vocal
tract profile view
