Early Speech and Language Development in a Child with Expressive Language Delay and Normally Developing Children: An Analysis of Phonetic Shapes and Syntactic Forms Otomo, Kiyoshi. RIEEC Annual Report (Dec 1998): 1-8.

Speech & language development in Japanese children was examined during the period of transition from the single-word stage to multi-word stage. Focus was on changes with age in the number of syllables constituting a word utterance & in the number of content words constituting an utterance. Study 1 concerned these changes in a Japanese boy with an expressive language delay who exhibited rapid progress. At 3:6, he displayed severe difficulty in expressive language compared to his auditory comprehension skills; his speech output was mostly single-word utterances, consisting of a single syllable, whereas his receptive vocabulary was almost comparable to his age. An analysis of speech samples showed an increase in his expressive vocabulary, the number of syllables constituting a word, & the number of content words in an utterance. In study 2, the speech of normally developing Japanese children (N = 3) were analyzed longitudinally at ages 1:8, 2:0, & 2:3. Results also showed a parallel increase in the number of syllables in a word & in the number of content words in an utterance. There was a marked progress in word shapes particularly between ages 1:8 & 2:0. Interestingly, this period coincided with the period when two-word combinations emerged & increased in the frequency of occurrence. The results suggested that the development of phonetic shapes & that of syntax interact with each other, or that they both operate on a common linguistic or cognitive basis. 5 Figures, 12 References.
