Despite early diagnosis, early fitting of more advanced sensory aids,
early intervention, and intensive educational management, many children
with severe to profound hearing loss are delayed in their acquisition of
spoken language compared with their peers with normal hearing. Some of
the greatest challenges facing educators of deaf children include
determining where to focus intervention in order to maximise benefit,
and establishing the most effective strategies for the development of
age-appropriate language. The experimental research in this book
examined the relationship between hearing, speech production, and
vocabulary knowledge, and investigated the contributions of these
factors to the overall speech perception performance of deaf children.
This research also investigated the areas in which intervention would be
most beneficial, and examined the effects of different types of
intervention on the development of spoken language and speech perception
skills in deaf children. The evaluation, analysis and intervention
methods reported in this book provide an experimentally validated
program for improving speech perception, speech production and spoken
language skills of deaf children.
