Real-time speech pattern element displays for interactive therapy.

New developments are presented and discussed for the interactive display and separate measurement of frication and nasality in addition to voice quality. Different clinical problems require different therapeutic and quantitative approaches and these are ideally supported by appropriate combinations of speech pattern elements. Particular use has been made of the laryngograph signal in order to solve the problems of analysis and so that the displays can be given both a sense of immediacy and be highly accurate.
