Metrical patterns of words and production accuracy.
This investigation examined the influence of metrical patterns of words (syllable stress and serial position) on the production accuracy of 20 children (22 to 28 months). The data were productions of six pairs of individualized two-syllable experimental words that referred to unfamiliar objects. Members of each pair differed only in the placement of stress (e.g., ['soti] vs. [so'ti]). Unstressed syllables were much more likely to be omitted, particularly at the beginning of words. Very few stressed syllables and unstressed second position syllables were omitted. One fourth of the word initial unstressed syllables were omitted. Consonant omissions, though few in number, tended to occur in initial position. Assimilation errors were not influenced by stress or serial position. When segmental errors due to syllable omissions were excluded, other consonant errors were not affected by stress or serial position. These findings indicate that young children's productions of syllables are influenced by the metrical patterns of words. However, the trochaic pattern of English is a statistical tendency, not an absolute constraint on two-syllable words. Metrical pattern also does not affect the consonant accuracy in syllables produced.
