Articulatory patterns of Russian diphthongized vowels: Pilot MRI investigation
نویسندگان
چکیده
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 dynamic patterns caused by specific role of core articulators in formation of heterogeneity of a speech sound. The first articulatory pattern supports gliding articulation of the vowel /ɨ/ through gradual displacement of tongue root and tongue blade/tongue dorsum towards anterior area of the buccal cavity, the other articulatory pattern is spatially and temporary realized through complex interaction of both tongue transformations and a special mandible articulatory gesture. Such exceptional jaw activity being unknown in common descriptions of the Russian articulatory base would make Russian vowel /ɨ/ a singular item within phonetic system of the Russian language.

On the diphthongized vowels in Qimen Hui Chinese
This paper gives an acoustic phonetic description of the diphthongized vowels in the Qimen Hui dialect. The results suggest that the diphthongized vowels in Qimen have similar acoustic phonetic properties with those in Yi County Hui, namely they belong to an intermediate category between monophthong and diphthong. However, the diphthongized vowels in Qimen are typologically closer to plain diph...

This paper is an acoustic phonetic description of the vowels and diphthongs in the Yi county dialect and compares the diphthongized vowels with monophthongs and diphthongs in terms of their temporal structures and spectral characteristics. Results show that rising diphthongs have two targets while falling diphthongs only have one dynamic target. Diphthongized vowels occur as an intermediate cat...
متن کاملA tagged-cine MRI investigation of German vowels
This project investigates the articulatory properties of German vowels on the basis of tagged Cine-MRI data. German has 15 monophthongs, which are classified into seven tense-lax pairs. Understanding the phonetic correlate of vowel tenseness has proven elusive, partly due to the difficulty of obtaining global shape information for the tongue, especially the pharyngeal portion. Tagged Cine-MRI a...

A three-dimensional on-line visualization of the vocal tract during speech production was performed based on MRI data obtained from a female speaker producing the six Russian vowels. These images were collected using original method of 3D MRI-scanning where the starting moments of MRI processes enabled co-operative activities from a patient’s side via a special remote-control device. A strobosc...
متن کاملA model based investigation of activation patterns of the tongue muscles for vowel production
Muscle activations in speech production are important for understanding speech control. To overcome the problems of previous methods, we proposed a physiological articulatory model based approach to explore the muscle activations in the production of the five sustained Japanese vowels through an optimization procedure which minimizes the morphological differences between the model simulations a...
