Shapes of the coronal section of the tongue of the consonant phonemes in Surgut Khanty according to electromagnetic articulography data

This paper describes he Surgu Khan y consonan s’ ongue ar icula ions following he electromagnetic articulography method provided by Carstens AG500. An articulography method includes special sensors a ached o speaker’s ar iculators with surgical glue. An electromagnetic field is used for real-time measurement of sensor coordinates. The experiment aimed to obtain the data on Surgut Khanty articulation, not described with instrumental techniques before. The analysis is based on more than 300 words pronounced by the native speaker of the Trom-Agan idiom. Three sensors on the tongue, two on the lips and two reference head movement tracking sensors were used. Audio files were annotated via Praat software. Raw data were treated with R programming language. The Emu-SDMS corpus system and R provided statistical evaluation and visualization. The shapes of the coronal section of the tongue were defined. The graphic forms of these shapes are presented. Coronal consonants /s/, /l/ are reali ed in den al apical shape. oronal consonan s / /, / n/, /r/, / ʃ/ are realized in laminal alveolar and, variably, in apical shape. oronal consonan /ɬ/ comes in pos alveolar shape. Dorsal consonan s / /, / /, /ɲ/, /с с / come in different palatal shapes. Radical consonants /k/, /γ/, /ŋ/ tend to have varying shapes like velar and palatovelar. Labial consonants /p/, /w/ have a neural ongue shape. The phenomenon of velar [γ] labiali a ion is considered. We have found labial w and velar γ in opposi ion after non-labial vowels. After labial vowels, this opposition is neu rali ed in consonan [γʷ]. I comes in velar and pala ovelar ongue shapes and has labial constriction. These facts differ in some aspects with the traditional theory and motivate further research.
