“…Using RTLA to simulate running speech constrains the vocal tract to unrealistic simplified geometries [4]. On the other hand, many continuous speech synthesizers use TLCA [2,6,16,17]. It is based on the electric-acoustic analogy: the vocal tract acoustics is seen as a lumped electric circuit.…”

“…Articulatory synthesis [1][2][3], or artificial talkers, are a useful technique to study acoustic, articulatory or physiological phenomena involved in speech production. They are generally based on articulatory models [1,3,4], or waveguide modulation models [2], that enable the evolution of the vocal tract geometry to be accurately defined using a few parameters driving the position and the shape of the articulators (jaw, tongue, lips, velum. .…”

This paper presents a simulation framework that enables a glottal chink model to be integrated into a time-domain continuous speech synthesizer along with self-oscillating vocal folds. The glottis is then made up of two main separated components: a self-oscillating part and a constantly open chink. This feature allows the simulation of voiced fricatives, thanks to a self-oscillating model of the vocal folds to generate the voiced source, and the glottal opening that is necessary to generate the frication noise. Numerical simulations show the accuracy of the model to simulate voiced fricative, and also phonetic assimilation, such as sonorization and devoicing. The simulation framework is also used to show that the phonatory/articulatory space for generating voiced fricatives is different according to the desired sound: for instance, the minimal glottal opening for generating frication noise is shorter for /z/ than for /Z/.

“…Similarly, there is intra-speaker variability, and it is thus interesting to add several repetitions of the sentences, or at least some of them. In previous work [11] we had worked with X-ray films [12] and so we added some of these sentences to compare both techniques of acquisition.…”

In this work we describe the creation of ArtSpeechMRIfr: a real-time as well as static magnetic resonance imaging (rtMRI, 3D MRI) database of the vocal tract. The database contains also processed data: denoised audio, its phonetically aligned annotation, articulatory contours, and vocal tract volume information, which provides a rich resource for speech research. The database is built on data from two male speakers of French. It covers a number of phonetic contexts in the controlled part, as well as spontaneous speech, 3D MRI scans of sustained vocalic articulations, and of the dental casts of the subjects. The corpus for rtMRI consists of 79 synthetic sentences constructed from a phonetized dictionary that makes possible to shorten the duration of acquisitions while keeping a very good coverage of the phonetic contexts which exist in French. The 3D MRI includes acquisitions for 12 French vowels and 10 consonants, each of which was pronounced in several vocalic contexts. Articulatory contours (tongue, jaw, epiglottis, larynx, velum, lips) as well as 3D volumes were manually drawn for a part of the images.
