We discuss speech production in terms of a mapping from a low-dimensional articulator space to low-dimensional manifold embedded in a high-dimensional acoustic space. Our discussion highlights the advantages of using an articulatory representation of speech. We then summarize mathematical results showing that, because articulator motions are bandlimited, a large class of mappings from articulat...

This paper presents a model for representing context-dependent variation of articulator movements. Our model explains the contextual e ect based on a multidimensional phonemic task and dynamic constraints of movements. The task determines the articulatory target so that invariant features of phoneme articulation are achieved. The dynamic constraints represent smoothly moving behavior of the art...

Past studies have demonstrated that reaction times in producing CV syllables are modulated by audio distractors participants hear while preparing their responses. Galantucci et al. [5] showed that participants respond faster on trials with identical response-distractor pairs than when the response and distractor differ in voicing or articulator. The dynamical model of phonological planning deve...

Focusing on general phonetics and its role in the world today, this paper explores what the term really means. Against a historical background, it outlines the development of general phonetics from its Victorian inception to the present day. It looks at the theoretical and practical sides of the subject (including ear-training and production training), and summarizes the IPA Certificate examina...

The accuracy with which virtual articulators are able to simulate centric and eccentric movements when fabricating definitive restorations has not yet been proven be on par mechanical have reliably used in restorative dentistry for decades. This may an issue working complex cases utilizing a digital workflow could result considerable chairside adjustment time subsequent loss of occlusal anatomy...

Arabic phonetics has been part of the study of Arabic language since the 7 th century CE. The great works by Al-Khali:l, "Kita:b al-'Ayn", and Si:bawayh, author of the first Arabic grammar book "al-kita:b" (i.e., "The Book") are the two cornerstones of this field. The early Arab grammarians knew phonetics quite well, although they mixed it with phonology, but interest in phonetics has remained ...

This study demonstrates a paradigm for modeling speech production based on neural networks. Using physiological data from speech utterances, a neural network learns the forward dynamics relating motor commands to muscles and the ensuing articulator behavior that allows articulator trajectories to be generated from motor commands constrained by phoneme input strings and global performance parame...

This paper reports results of a study investigating the visual information conveyed by the dynamics of internal articulators. Intelligibility of synthetic audiovisual speech with and without visualization of the internal articulator movements was compared. Additionally speech recognition scores were contrasted before and after a short learning lesson in which articulator trajectories were expla...

This paper presents an estimation method of the vocal tract spectrum from articulatory movements. The method is based on the interpolation of spectra obtained by phonemedependent neural networks. Given the phonemic context and articulation timing corresponding to each phoneme, the proposed method first transforms articulator positions to phoneme-dependent spectra. Then the vocal tract spectrum ...
