Abstract:
Работа выполнена в рамках исследований речи русскоязычных детей с типичным и атипичным развитием, проводимых группой по изучению детской речи СПбГУ (Ляксо, Фролова, 2018). Специфика пренатального и раннего постнатального развития близнецов позволяет отнести их к группе риска по речевому и когнитивному развитию по сравнению с одиночно рожденными детьми. Цель работы - проследить изменение акустических характеристик речи детей-близнецов в период с 6 до 14 лет. Участники исследования - 10 дизиготных близнецов в возрасте от 6 лет до 14 лет. Проводили аудиозапись и видеосъемку речевого поведения детей в стандартных ситуациях взаимодействия с матерью. Уровень речевого развития близнецов оценивали с применением методов перцептивного, фонетического, инструментального спектрографического анализа. Показаны различия по временным, спектральным характеристикам гласных из слов детей. Значения частоты основного тона (ЧОТ) гласных из слов первых по порядку рождения шестилетних детей имеют более низкие значения. Формантные ... : Present work is a part of studies of Russian children speech formation in conditions of typical and atypical development, conducted by child speech research group of St. Petersburg State University (Lyakso, Frolova, 2018). The specificity of prenatal and early postnatal development of twins allows them to be classified as a risk group for speech and cognitive development compared to single-born children. The aim of the study is to reveal the changes in the acoustic characteristics of the speech of twin children in the period from 6 to 14 years. 10 dizygotic twins at the age of 6 to 14 years participate in the study. Audio and video recording of children's speech behavior in standard situations of interaction with the mother were carried out. The level of speech development of the twins was assessed using methods of perceptive, phonetic and instrumental spectrographic analysis.Differences in temporal and spectral characteristics of vowels in children's words are shown. The pitch in vowels from the words of ...
