Simulating alveolar trills using a two-mass model of the tongue tip.

چکیده
This paper investigates the possibility of reproducing the self-sustained oscillation of the tongue tip in alveolar trills. The interest is to study the articulatory and phonatory configurations that are required to produce alveolar trills. Using a realistic geometry of the vocal tract, derived from cineMRI data of a real speaker, the paper studies the mechanical behavior of a lumped two-mass model of the tongue tip. Then, the paper proposes a solution to simulate the incomplete occlusion of the vocal tract during linguopalatal contacts by adding a lateral acoustic waveguide. Finally, the simulation framework is used to study the impact of a set of parameters on the characteristic features of the produced alveolar trills. It shows that the production of trills is favored when the distance between the equilibrium position of the tongue tip and the hard palate in the alveolar zone is less than 1 mm, but without linguopalatal contact, and when the glottis is fully adducted.

Self-oscillating Models of the Tongue Tip for Sim- Ulating Alveolar Trills
Alveolar trills are sounds produced by the self-oscillation of the tongue tip in the alveolar region. Specific aeroacoustic conditions around the lingual constriction are required to produce such sounds, but have not been fully investigated dueto the lack of physical modeling. This study discusses the possibility to model the tongue tip behavior with lumped mass-spring systems similar to those ...
متن کاملThe quasisteady approximation in speech production.
Because boundary-layer separation is important in determining force between flowing air and solid bodies and separation can be sensitive to unsteadiness, the quasi-steady approximation needs to be examined for the flow-induced oscillations of speech (e.g., phonation and trills). A review of the literature shows that vibratory phenomena, such as phonation and tongue-tip trills, may need to be mo...
متن کاملWhat role does the palate play in speech motor control? Insights from tongue kinematics for German alveolar obstruents
By means of simultaneous EMMA and EPG recordings we investigated tongue tip kinematics and tongue palate contact patterns for four German speakers in order to compare production strategies of alveolar stops with fricatives. We assumed that the central nervous system integrates the palate in the speech motor control process and that tongue palate contact patterns influence the kinematic properti...
متن کاملCoordination of tongue tip and body in place differences among English coronal obstruents
Using electromagnetometry tracking of the tongue, Best et al. (2010, 2014) have demonstrated that Wubuy, an Australian language with four coronal stop places, shows significant differences in tongue tip vs. tongue body motion range and motion coordination contrasting apicals and laminals. Here we continue this line of inquiry with three coronal obstruents in English, the apical alveolar stop /d...
متن کاملComparison Among Phonation of the Sustained Vowel /ε/, Lip Trills, and Tongue Trills: The Amplitude of Vocal Fold Vibration and the Closed Quotient
Trill exercises are traditionally used in the clinical practice of speech-language pathology as vocal warm-ups in the treatment of dysphonia (Behlau & Pontes, 1995; Sataloff, 1991). They are also used by voice coaches (Aydos & Hanayama, 2004; Scarpel & Pinho, 2001) in the training of professional voice users, such as singers, actors (including voice actors), teachers, and lawyers. Although ther...
