Children's speech and language development is measured by performance on standardized articulation tests. Test items on these assessments, however, vary in length and complexity. Word complexity was compared across five articulation tests: the Assessment of Phonological Patterns-Revised (APP-R), the Bankson-Bernthal Test of Phonology (BBTOP), the Clinical Assessment of Articulation and Phonology (CAAP), the Goldman-Fristoe Test of Articulation (GFTA), and the Assessment of Children's Articulation and Phonology (ACAP). Four groups of word complexity were used, using the dimensions of monosyllabic vs. multisyllabic words, and words with consonant clusters vs. words without consonant clusters. The measure of phonological mean length of utterance (Ingram, 2001), was used to assess overall word complexity. It was found that the tests varied in number of test items and word complexity, with the BBTOP and the CAAP showing the most similarity to word complexity in spontaneous speech of young children. On the other hand, the APP-R used the most complex words and showed the least similarity. Additionally, case studies were analyzed for three of the tests to examine the effect of word complexity on consonant correctness, usedin the measures of Percentage of Correct Consonants (PCC) and the Proportion of Whole Word Proximity (PWP). Word complexity was found to affect consonant correctness, therefore affecting test performance.

Early childhood language environment has an important effect on developmental language outcomes. Intervention and parent training for children who have speech and language delays often focuses on the implementation of strategies designed to enhance the language environment. With quantitative information on different aspects of the language environment, intervention and parent training can be better tailored to the needs of each child and can be made easier for parents to implement. This study uses the Language Environmental Analysis (LENA) system to explore differences in language environment across participants, settings (toddler group and home), and activities (general, outside, and organized playtime, story time, meal time, naptime, transition, public outside visits, travel time, TV time, personal care, and other). Participants were five children, ages 20-35 months who had speech and language delays. The children wore the LENA for one day and the adult words to the child, child vocalizations and turn-taking were analyzed during each activity and setting. We found that general and outside playtime activities, meal time, and personal care times were activities that consistently resulted in high levels of child vocalization across participants. Structured play and story time did not result in high levels of child vocalization. We also found that, for some children, there were differences in the quantity of adult language addressed to the child in language group and home settings. These findings have implications for training parents to provide language rich environments for their child.
