Abstract

The speech sounds of twenty-nine infants from the sixteenth to the eighteenth months were transcribed in the International Phonetic Alphabet. Comparisons were made of vowel and of consonant frequencies as between each of the three months. Further comparisons were made with other age groups in order to show the developmental status of the use of speech elements of the age group.
