An Acoustically Oriented Vocal-Tract Model
The objective of this paper is to nd a parametric representation for the vocaltract log-area function that is directly and simply related to basic acoustic characteristics of the human vocal-tract. The importance of this representation is associated with the solution of the articulatory-to-acoustic inverse problem, where a simple mapping from the articulatory space onto the acoustic space can b...
متن کاملIntelligibility of monosyllabic words produced by an acoustically-driven model of the vocal tract
A model of speech production is a tool that can provide insight into the relation of articulatory processes and acoustic characteristics present in a speech signal. When such a model includes components representing the voice source, acoustic wave propagation, and vocal tract movement it can produce actual speech that can be listened to and evaluated as if it were produced by a human. In this c...
متن کاملRelation of vocal tract shape, formant transitions, and stop consonant identification.
PURPOSE The present study was designed to investigate the relation of formant transitions to place-of-articulation for stop consonants. A speech production model was used to generate simulated utterances containing voiced stop consonants, and a perceptual experiment was performed to test their identification by listeners. METHOD Based on a model of the vocal tract shape, a theoretical basis f...
متن کاملSliding vocal-tract model and its application for vowel production
In a previous study, Arai implemented a sliding vocal-tract model based on Fant’s three-tube model and demonstrated its usefulness for education in acoustics and speech science. The sliding vocal-tract model consists of a long outer cylinder and a short inner cylinder, which simulates tongue constriction in the vocal tract. This model can produce different vowels by sliding the inner cylinder a...
متن کاملA parametric model of the vocal tract area function for vowel and consonant simulation.
A model of the vocal-tract area function is described that consists of four tiers. The first tier is a vowel substrate defined by a system of spatial eigenmodes and a neutral area function determined from MRI-based vocal-tract data. The input parameters to the first tier are coefficient values that, when multiplied by the appropriate eigenmode and added to the neutral area function, construct a...
