Abstract

The durational characteristics of novel words produced in repeated trials were evaluated in separate groups of children with, and without speech delay (SD). Children produced disyllabic novel words containing either a trochaic or iambic stress pattern. Results of acoustic analysis indicated a significant interaction between trial number and speaker group. The duration of words produced by children without SD decreased more abruptly across successive trials as compared to children with SD. In addition, duration decreased at a faster rate for trochaic words as compared to iambic words in both groups. Variability of word duration was greater in iambs than trochees. The results are discussed in terms of speech motor learning patterns that may underlie difficulties associated with SD.
