title: Speech production time and judgments of disordered nasalization in speakers with cleft palate.
abstract: The purpose of this study was to investigate the effect of production time on the perception of disordered nasalization in children with cleft palate. The subjects with cleft palate included 5 who produced acceptable speech consistently, 5 who produced disordered nasalization consistently, and 10 who were inconsistent in the production of disordered nasalization. We examined a range of production times similar to those for the production of single-word and connected speech tasks. Ten judges used direct magnitude estimation to rate severity of disordered nasalization. An accelerometric ratio technique was used to estimate the extent and timing of nasal acoustic activity. The results showed that reducing the production time did not change perceptible nasalization.
