Аннотация:COMPARATIVE ANALYSIS OF SPEAKER'S RESPIRATORY ACTIVITY AT REST AND WHEN READING PROSAIC AND POETIC TEXTS (UPON RESULTS FROM ONLINE MRI). The paper presents preliminary results of the MRI investigation of respiratory strategies of Russian speakers when reading a poem and a prosaic text (short story), in comparison to their breathing in silence. MRI protocols optimized for online visualization of lung function were applied to register breathing behavior of 4 native Russian speakers. To obtain a numerical value for the total area of active segments of lungs in each reading mode, compared to the one in rest, special processing of collected MRI images has been carried out. For each respiratory mode, the minimum and maximum values of the total area of active segments of the lungs, as well as median values and dispersion were calculated. The paper presents digitalized data of the breathing activity for one speaker. These results show an approximately 1.6-fold increase in the total area of active segments of the right and left lungs during reading compared with similar data for silence. The results also demonstrated constancy of increased lung volume throughout the process of phonation. Verification of the data with Mann–Whitney U test showed systemic differences between respiratory processes in speech production and breathing in silence.
