This study is a first report of a combination of two linked projects. Sound
productions of deaf and hearing children were studied longitudinally from 2.5
until 18 months of age in order to establish in which respect the sound
productions of deaf children are influenced by lack of auditory perception.
Differences between deaf and hearing children were found in number of spoken
utterances and in type of articulation and phonation. Results indicate that
children’s sound productions are influenced by auditory perception from a
very early age onwards and that from about 9 months onwards differences in
utterance types are quite obvious.
