This study examined early vocal production to assess whether it is possible to identify predictors of vocabulary development prior to the age point at which lexical delay is usually identified. Characteristics of babbling and first words in 12 Italian children with slow expressive development (late talkers; LT) were compared with those of 12 typically developing (TD) peers. Syllable structure and phonetic characteristics of babbling and first words produced by both groups of children at 20 months were analysed during mother-child play sessions. Results indicated that phonetic complexity and number of consonantal types were lower in the LT group. The two groups also differed in their use of sound classes and their syllable structure. Overall, it can be said that LTs development is similar to (but slower than) TDs, as opposed to having an atypical pattern of phonological development.

Abstract

This study examined early vocal production to assess whether it is possible to identify predictors of vocabulary development prior to the age point at which lexical delay is usually identified. Characteristics of babbling and first words in 12 Italian children with slow expressive development (late talkers; LT) were compared with those of 12 typically developing (TD) peers. Syllable structure and phonetic characteristics of babbling and first words produced by both groups of children at 20 months were analysed during mother-child play sessions. Results indicated that phonetic complexity and number of consonantal types were lower in the LT group. The two groups also differed in their use of sound classes and their syllable structure. Overall, it can be said that LTs development is similar to (but slower than) TDs, as opposed to having an atypical pattern of phonological development.
