Since Lieberman and Crelin (1971) postulated the theory that Neandertals “could not
produce the range of sounds that characterize human speech”, the potential speech …

Modeling speech production and speech articulation is still an evolving research topic.
Some current core questions are: What is the underlying (neural) organization for controlling …

In this study the acoustic and articulatory variabilities of speakers with different palate
shapes were compared. Since the cross-sectional area of the vocal tract changes less for a …

Acoustic-to-articulatory inversion is a difficult problem mainly because of the nonlinearity
between the articulatory and acoustic spaces and the nonuniqueness of this relationship. To …

This paper discusses the use of surface electromyography (EMG) to recognize and
synthesize speech. The acoustic speech signal can be significantly corrupted by high noise …

The remarkable capacity of the speech motor system to adapt to various speech conditions
is due to an excess of degrees of freedom, which enables producing similar acoustical …

Studies on vocal tract shape estimation from the speech signal have thoroughly established
that no unique inversion from the acoustic speech signal to the vocal tract area function is …

This paper investigates the functional relationship between articulatory variability and
stability of acoustic cues during American English/r/production. The analysis of articulatory …

In individuals with Down syndrome, hypotonicity of the tongue and an underdeveloped
maxilla may lead to poor oral motor coordination, which adversely affects the oral phase of …

This paper presents a comparative study of transformations used to compute the area of
cross-sections of the vocal tract from the mid-sagittal measurements of the vocal tract. MRI …
