The dictionary is meant to be used for producing pronunciation, i.e. transcriptions, while reading all sorts of Swedish text material. An important fundamental principal is to make the dictionary accessible to users unfamiliar with the Swedish language. Further the dictionary will incorporate as many words in a text material as possible, i.e. even the names of people, places, companies, models, etc. The aim of this project is to study the movements of the lower jaw and the lips during normal and pathological speech phrases. Movement registration is made by means of computer-based Selspot equipment Unlike other studies in this field, the material consists of phrases and not isolated syllables.
Special attention is given to mandibular movements in relation to the syllabic structure.
Results are related to current hypotheses about the motoric control of speech. An important goal is producing objective test methods for Parkinsons disease and other speech disturbances. The main aim is to analyze variations in the front tongue groove and to relate the data to mandibular movements and acoustic patterns within the framework of recently developed sibilantic articulatory models. In mechanical models of the vocal tract, systematic variations will be made in the front dental and aveolar shape and size. The sound produced by an air jet hitting this region will be studied acoustically and perceptually.
