- W2170478244 abstract "The corpus used to observe the variations of the velar positions during consonants and vowels was constituted of a single occurrence of all the symmetric [#VCV#] sequences where C is one of the French consonant [RVMDF IHU5X<ONOP ], and V one of the French oral or nasal vowels [C'GK[WQ1nu#�'�n� u� ]. A complementary corpus, constituted of series of sequences [pVCVp] repeated five times, the consonant C being restricted to [RD OVFP], was used to compare more precisely nasal stops, voiced and voiceless oral stops having the same place of articulation, labial or dental. One single male French subject has been recorded so far. This study deals with the effects of spatial and contextual coarticulation on the velar position in vowels and consonants, and on the associated acoustic outputs. We present first an articulatory analysis of velar movements for consonants and vowels recorded for a French male subject uttering a corpus of VCV sequences. The velum in nasal consonants appears to be surprisingly high in comparison with nasal vowels. Moreover, a clear overlap between the ranges of velum height for oral vowels and nasal consonants was found. A strong carryover effect was observed for vowels at the articulatory level, though this did not systematically result in significant effects on the acoustic spectral peaks. Anticipatory velar movements were never observed. Articulatory movements and speech sound have been recorded synchronously. One of the coils of an electromagnetic midsagittal articulograph (EMA) was attached to the velum at about half way between the junction of the hard palate and of the velum and the extremity of the uvula of the subject, in the most mobile region of the velum, so as to provide an estimation of the velum movements (see Figure 1). The vertical displacement of the coil is called hereafter velum height (note that the origin of the coordinates is arbitrary, the X horizontal axis being nearly aligned with the occlusal plane). The articulatory movements were sampled at 500 Hz, while the speech signal was sampled at 20 kHz. The articulatory analysis concerned both coordinates of the velum coil, sampled at the centres of vocalic and consonantal segments that had been manually labelled." @default.
