Assessment of speech sound production in young children provides the basis for diagnosis and treatment of speech sound disorders. Standardized single-word articulation tests are typically used for identification of speech sound errors because they can provide an efficient means of obtaining a speech sample for analysis and comparison to same-age peers. A major criticism of single-word articulation tests is that they may not accurately reflect speech sound production abilities in conversation. Comparison of performance in single-word and conversational contexts has produced conflicting results in the available research. The purpose of the present study was to compare speech samples obtained using an extensive single-word naming task with samples of continuous speech elicited by sentence imitation. It was hypothesized that there would be differences in overall speech sound production accuracy as well as differences in types and frequency of errors across the two sampling conditions. The present study is a pilot investigation as part of the development of the Phonological and Bilingual Articulation Assessment, English Version (PABA-E; Gildersleeve-Neumann, unpublished). Twelve preschool children ages 3;11 to 4;7 (years;months) from the Portland Metropolitan area participated in this study. Participants were monolingual native English speakers and exhibited typical speech sound development as measured by the GFTA-2 (Goldman-Fristoe, 2000). Hearing acuity for participants was within acceptable limits, and participants' families reported no significant illnesses or developmental concerns that would impact speech sound production abilities. Mean t-scores for percentage of consonants correct (PCC) in the single-word samples were significantly higher at the .05 level than those for the sentence imitation samples. There was no significant difference between the percentage of vowels produced correctly (PVC) in the two sampling conditions. Similar types of error patterns were found in both the single-word and continuous speech samples, however error frequency was relatively low for the participant population. Only the phonological process of stopping was found to be significantly different across sampling conditions. The mean frequency of occurrence for stopping was found to be significantly higher in continuous speech as compared with the production of single-words.
