An efficient model of hyper textual authoring processes and guidelines for electronic multi-media educational and scientific resources’ development in Philology is being discussed. The model was successfully applied for construction of the interactive hyper-media e-learning Web-resource “Russian Dialectal Phonetics”. The electronic public educational and research resource in Russian Dialectology is the first and unique one fully based on SCORM ideology. Basic authoring algorithms were adopted from the object-oriented programming (OOP) and Rapid Application Design (RAD) ideology and practice for application. The e-course comprises two major components: a theoretical overview and practical sections (on-line self-tests, exercises). An interactive glossary of linguistic and other special terms is also appended through the network of hyperlinks. As essential multi- and hypermedia product the course comprises texts, image illustrations (dialect maps included), authentic dialectal spoken language recordings from the archive of dialectological expeditions.

 

 

 

The research in question is aimed at the experimental MRI-investigation of articulatory gestures corresponding to Russian bilabial non-palatalized phonemes [b] and [m]. Being estimated as the prominent type of velarized consonants in Russian, these phonemes have been taken as target group in a series of MRI experiments to study palatalisation – velarisation relationship in the Russian phonetic system. An experimental dataset was based upon 2D MR-images, audio- and video recordings taken from 2 native speakers of Russian (male and female) producing VCCV sequences (Russian pseudo-words with the second vowel stressed) containing labial consonants in the vocalic contexts [a]_[a], [a]_[e]. The original experimental method of MRI investigation relied on gated and time-related MR-scanning of numerous repetitions of the same speech sequence for further reconstruction of articulatory movement(s) progressing in time being plotted from MR-images across several repetitions within a session.

 

 

 

The MRI investigation of Russian vowels articulation inventory was realized upon original technology elaborated by the authors for real-time visualization of the speech articulation dynamics. One series of experiments dealt with articulation of the Russian sustained vowels. The data was collected in the course of several experimental sessions with the time gap of one months and one year. In all sessions the highest degree of MRI matching within various productions of a particular vowel by the same speaker was observed. Russian vowels articulation inventory was thus defined and confronted with corresponding data of the Korean one. Articulation of vowels in both languages is estimated to be the best evidence of the language-specific articulation base. The factual identity of the Russian vowels articulation thus could be explicitly stated and appropriate instructions for the language teaching and learning elaborated.

 

 

 

The research is focused on experimental methods and technology for detailed MR-visualization of solid calciferous tissue boundaries (i.e. teeth and adherent bony structures) and estimation of overall resonance shape throughout the speech production process. Vocal tract area evaluation from MRI data requires a special technique for tooth visualization because of the lack of signal from the teeth as objects consisting of solid calciferous tissue. In this paper, a new method is proposed to capture MR-images of this kind of biological objects and accurately superimpose their outlines onto MRimages of sagittal plane of articulatory tract. Upper and lower incisors’ MR-images with the surrounding bony structure are obtained by MR-scanning a subject with a contrast medium enveloping teeth’s surfaces.

 

 

 

В речевой артикуляции, как в фокусе, самым естественным образом отражаются все базовые свойства языка - социальная и индивидуальная природа языковой деятельности, ее зависимость от общих законов физиологии и психологии (в первую очередь, двигательной активности), нейрофизиологические и анатомические особенности производства речи, высокая степень организационной системности и иерархичности. Многоаспектность природы речевой артикуляции делает ее, с одной стороны, достаточно сложным объектом исследования, однако с другой - способствует привлечению к изучению этого аспекта языковой деятельности всего широкого спектра приборов, методов и методик, разработанных в сфере естественнонаучного знания, т.е. делает речевую артикуляцию одним из самых естественных и многообещающих объектов междисциплинарного исследования.

 

 

 

В докладе представлены промежуточные результаты работ, выполняемых в МГУ им. М.В. Ломоносова в рамках инициативного междисциплинарного проекта, основной целью которого является разработка методик использования новейших технических средств (магнитно-резонансной томографии) в исследовании механизмов речепорождения.

The purpose of this article is to analyse the concept of computerbased learning environment and to submit guidelines for building up an Internet-based learning environment in Russian Phonetics. The analysis is based on a fundamental notion of learning environment and discusses also current semantics of some special terms: distance education, hypertextuality, computer-aided curriculum and adaptive system of a controlled and directed testing (up to the moment – phonetic exerciser).

 

 

 

 

 

The research in question is aimed at the experimental MRI-investigation of articulatory gestures corresponding to the soft Russian stop consonants [p’], [t’], [k’], [b’], [d’], [g’] and spirants [s’], [z’], [h’] countered with their hard counterparts [p], [t], [k], [b], [d], [g], [s], [z], [h] in Russian speech production. An experimental dataset was based upon 2D MR-images, audio- and video recordings taken from 4 native speakers of Russian producing VCCV sequences (Russian pseudo-words with the second vowel stressed) containing Russian consonants under investigation in the vocalic contexts [a]_[a], [a]_[e], and [i]_[i]. Allspeaking subjects had standard pronunciation and were without any perceptible articulation disease. MRI investigation of the Russian consonantal phonemes was based upon admitted procedures and techniques though expanded with several new original methods elaborated by the Russian team of experimentalists.
