Phonological substitution processes of a hard of hearing child
This is an investigation in the generative framework of phonological substitution processes of a 6 yr old child with a moderately severe sensorineural hearing loss. The child's substitutions had much in common with the substitutions of younger normal children. For instance, as commonly occurs with normals, liquid consonants were replaced in this child's speech by glides and rounded vowels, final fricative consonants were devoiced, and consonants in general were shifted to more forward places of articulation. To account adequately for the data from this hard of hearing child, it was necessary to invoke some of the same sorts of ordering restrictions (on rule application) that have been found necessary in the description of substitution processes of normal children.
