Speech visualization is extended to use animated talking heads for computer assisted pronunciation training. In this paper, we design a data-driven 3D talking head system for articulatory animations with synthesized articulator dynamics at the phoneme level. A database of AG500 EMA-recordings of three-dimensional articulatory movements is proposed to explore the distinctions of producing the so...

Foreign language learners tend to avoid phonological difficulties and simply transfer sounds whether from their L1 or any pre-existing L2. Phonological awareness (PA) gives students an active role in understanding their own potential in improving pronunciation through several methods. However, such methods are likely to be restricted to only passive learning methods, such as repetition, reading...

In this paper work, past, present and future, in articulatory synthesis applied to Portuguese is presented 1 .

This study investigated how vowel epenthesis, a typical suprasegmental error produced by Japanese learners of English, is realized in their speech production of L2 English. We investigated two aspects: (i) whether loanword epenthesis phonology in Japanese transfers to English speech production, and (ii) how learners’ English proficiency level affects vowel epenthesis. In Japanese loanword phono...

Three experiments with undergraduate student participants investigated whether high frequency nonword syllables of English and non-existing English syllables showed differential effects on response latency, accuracy, onset and rime duration or spectral measures of coarticulation in syllable naming tasks. Only the coarticulation data provided any support for the hypothesis that speakers store ar...

Fundamental to the success of the articulatory based speech coding is the mapping from acoustics to articulatory description. As the mapping is not unique and based on articulatory continuity criteria, the non-uniqueness of the articulatory trajectories is solved using a forward dynamic network. In this paper, we present new results on forward dynamic network used to estimate articulatory traje...

Articulatory features are proved to be efficient in the area of speech recognition and synthesis. However, acquiring articulatory has always been a difficult research hotspot. A lightweight accurate model is significant meaning. In this study, we propose novel temporal convolution network-based acoustic-to-articulatory inversion system. The acoustic feature converted into high-dimensional hidde...

Our acoustic to articulatory inversion method exploits an original articulatory table structured in the form of a hypercube hierarchy. The articulatory space is decomposed into regions where the articulatory-to-acoustic mapping is linear. Each region is represented by a hypercube. The inversion procedure retrieves articulatory vectors corresponding to an acoustic entry from the hypercube table....
