Theoretical and descriptive phonetics:
Serial ordering and motor control of speech production: articulatory
dynamics – coarticulation - sensory feedback control
of speech - tongue slips
Physiological, aerodynamic and perceptual explanations for
Articulatory / acoustic correlations in speech production
Cross-language studies of fricatives
Instrumental phonetic methods in diagnosis, assessment and
rehabilitation of children and adults with phonetic and phonological
disorders (particularly in cleft palate, dysarthria, aphasia,
hearing impairment and Down's Syndrome)
Aerodynamic and phonological correlates of disorders of fluency
(particularly stuttering and cluttering)
Linguistic and motor speech profiling of stuttering behaviour
Development of Electropalatography ( EPG ) for recording and
measuring tongue activity during speech
Abnormal sibilant production
