This paper investigates the functional relationship between articulatory variability and stability of acoustic cues during American English /./ production. The analysis of articulatory movement data on seven subjects shows that the extent of intrasubject articulatory variability along any given articulatory direction is strongly and inversely related to a measure of acoustic stability ~the exte...

This paper presents a novel approach to recovering articulatory trajectories from the speech signal using a variational calculus method and Maeda’s articulatory model. The acoustic-toarticulatory mapping is generally assessed by a double criterion: the acoustic proximity of results to acoustic data and the smoothness of articulatory trajectories. Most of the existing methods are unable to explo...

This paper investigates the functional relationship between articulatory variability and stability of acoustic cues during American English /r/ production. The analysis of articulatory movement data on seven subjects shows that the extent of intrasubject articulatory variability along any given articulatory direction is strongly and inversely related to a measure of acoustic stability (the exte...

The large corpus of real time magnetic resonance image sequences of the vocal tract during speech production that was recently acquired and can be referred to as MRI-TIMIT, provides us with a unique platform for systematically studying articulatory dynamics. Compared to previously collected articulatory datasets, e.g., using articulography or X-rays, MRI-TIMIT is a rich source of information fo...

Using articulatory features for speech recognition improves the performance of low-resource languages. One way to obtain articulatory features is by using an articulatory classifier (pseudoarticulatory features). The performance of the articulatory features depends on the efficacy of this classifier. But, training such a robust classifier for a low-resource language is constrained due to the li...

Paper presents main results of a targeted MRIinvestigation of articulatory patterns of the Russian diphthongised (gliding) vowel phonemes, vowel /ɨ/ first and foremost. The investigation‟s relevance is assured by serious general discordance of opinions discussing articulatory patterns of diphthongised Russian vowel /ɨ/. Our research revealed critical differences in the vowel‟s articulatory dyna...

We study the effect that phonetic onset has on acoustic and articulatory reaction times. An acoustic study by Rastle et al. (2005) shows that the place and manner of the first consonant in a target affects acoustic RT. An articulatory study by Kawamoto et al. (2008) shows that the same effect is not present in articulatory reaction time of the lips. We hypothesise, therefore, that in a replicat...

ABSTRACT: Statistical articulatory modeling is based on the analysis of a collected speech corpus to extract parameters that should be able to resynthesize the articulatory movements in the original corpus. As the parameters are based directly on the corpus, the size and content of the corpus have important effects on the model. In this paper we compare statistical articulatory models based on ...
