Objectives: Objective measures of speech are necessary in order to validly and reliably assess whether a child can demonstrate appropriate phonological developments when compared to typically developing children of the same age. This study aimed to investigate 5 speech measures based on phonological analyses of spontaneous conversations. It examined whether the speech measures indicated phonological developmental patterns and how they were related to each other.
Methods: The participants of this study were 50 typically developing children between the age of 18-47 months and they were divided into 5 age-groups (6-months interval with, 10 children per group). Spontaneous conversational speech samples were obtained and 5 measures (consonant inventory, speech intelligibility, percentage of correct consonant, percentage of correct consonant-revised, and phonological mean length of utterance) were analyzed thereafter. Multivariate analyses of variance were conducted to determine whether there were significant differences of measures among the age groups and to what extent the relationships were shown among such measures.
Results: All the speech measures showed statistically significant differences among the age groups. Specifically, the speech measures indicated that typically developing children displayed the biggest phonological developments between 1;6 and 2;11. In addition, there were significant relationships of all the speech measures.
Conclusion: This study suggested that the five objective speech measures from phonological analyses of spontaneous conversations could be used to assess phonological developments of children.
