A comparative study of two-dimensional vocal tract acoustic modeling based on Finite-Difference Time-Domain methods
Debasish Ray Mohapatra, Victor Zappi, Sidney Fels
The two-dimensional (2D) numerical approaches for vocal tract (VT) modelling can afford a better balance between the low computational cost and accurate rendering of acoustic wave…
SPEAK WITH YOUR HANDS Using Continuous Hand Gestures to control Articulatory Speech Synthesizer
Pramit Saha, Debasish Ray Mohapatra, Sidney Fels
This work presents our advancements in controlling an articulatory speech synthesis engine, \textit{viz.}, Pink Trombone, with hand gestures. Our interface translates continuous fi…
Sound-Stream II: Towards Real-Time Gesture Controlled Articulatory Sound Synthesis
Pramit Saha, Debasish Ray Mohapatra, Praneeth SV +1
We present an interface involving four degrees-of-freedom (DOF) mechanical control of a two dimensional, mid-sagittal tongue through a biomechanical toolkit called ArtiSynth and a…
Limitations of Source-Filter Coupling In Phonation
Debasish Ray Mohapatra, Sidney Fels
The coupling of vocal fold (source) and vocal tract (filter) is one of the most critical factors in source-filter articulation theory. The traditional linear source-filter theory h…
