Distinctive features of consonantal errors in deaf children

Pictorial stimuli of 18 consonants in 3 vocalic positions were presented to 10 deaf children; verbal responses were phonetically transcribed. Consonantal substitution errors were submitted to INDSCAL analysis. A 2-dimensional solution revealed features relating mainly to place of articulation and indicated that current habilitation procedures focus primarily on those features while not exploiting others available in the speech signal.
