speech delay and impairment

[Paul Sharples, UK, pgshar]

I am a final year linguistics student undertaking a
dissertation on the effects of oral clefts on the development of
speech. I would appreciate information from anybody who has had
experience of cleft palate. In particular, I would like
information from speech therapists/pathologists or parents whose
child/ren have undergone speech therapy. If you could provide me
with data on problem speech sounds, speech characteristics (eg
hypernasality) and any communication problems, I would be
extremely grateful. My e-mail address is above. Thankyou in
advance for any help you can give me.
