Magnetic resonance measurements of the velum port opening

چکیده
M.R.I. techniques have been used to describe velum opening of French vowels. Data based on 18 joined axial slices of 4 mm thickness were recorded with two subjects. Differences in vclum opening are calculated from areas measured in the tract between the lowered velum and the back pharynx wall. A 3 D modelling of this tract is also proposed.

Determination of velum opening for French nasal vowels by magnetic resonance imaging.
MRI techniques have been used to describe velum opening of French vowels. Data based on 18 joined axial slices of 4 mm thickness were recorded with four subjects. Differences in velum opening are calculated from areas measured in the tract between the lowered velum and the back pharynx wall. Results show that for all subjects, the back vowel [symbol: see text] has the smallest opening, while so...
متن کامل2D Articulatory velum modeling applied to copy synthesis of sentences containing nasal phonemes
Articulatory synthesis could become a valuable tool to investigate links between articulatory gestures and acoustic cues. This papers presents the construction of an articulatory model of the velum which is intended to complete a model already comprising other articulators. The velum contour was delineated and extracted from a thousand of X-ray images corresponding to short sentences of French....
متن کاملMagnetic resonance imaging of feline eye
The purpose of this study was to investigate magnetic resonance imaging (MRI) of the normal feline eyeand optic nerves using T1-weighted and T2-weighted images. A total of 6 healthy female domestic short haircats age 2-2.5 years and weighing 3.2 ± 0.4 kg were selected. Magnetic resonance imaging data werecollected using GEMSOW (Philips) at a magnetic field strength of 1.5 T. Dorsal, sagittal, a...
متن کاملRecovering gestures from speech signals: a preliminary study for nasal vowels
For nasal vowels, a gesture as simple as the lowering of the velum produces complex acoustic spectra. However, we still find a relative simplicity in the perceptual space; nasality is perceived easily. In this preliminary study, we use statistic method to recover the gesture of the velum. In order to reduce the extreme variability of nasal vowels, we introduced a simulation based on Maeda’s mod...
متن کاملApplication of Magnetic Resonance Imaging (MRI) as a safe & Application of Magnetic Resonance Imaging (MRI) as a safe & non-destructive method for monitoring of fruit & vegetable in postharvest period
To investigate and control quality, one must be able to measure quality-related attributes. Quality of produce encompasses sensory attributes, nutritive values, chemical constituents, mechanical properties, functional properties and defects. MRI has great potential for evaluating the quality of fruits and vegetables. The equipment now available is not feasible for routine quality testing. The ...
