Which phonological and lexical factors best influence whether a word is produced and pronounced well?

This study examines lexical and phonological factors that influence word production and pronunciation. Specifically, we investigate whether phonological production (measured by percent consonants correct) contributes to word production and pronunciation over and above the properties of the target words (e.g., word frequency, neighborhood density, and phonetic complexity). Forty French-speaking monolingual and bilingual children, aged 1;11 to 3;1, participated in a spontaneous language sample and were administered a naming and a nonword repetition task. Their parents filled out the MacArthur Communicative Developmental Inventory (MCDI) and rated their children's pronunciation on an experimental version of the MCDI. Statistical models indicated that word frequency and the phonetic complexity of the target words influenced whether a word was produced. These factors along with neighborhood density and the children's production capacities influenced whether a word was pronounced poorly or well. Findings indicate that parents can provide reliable information on the word pronunciation of their children.
