Electropalatography and the Linguagraph system

This paper describes the technique of electropalatography and the developme nt of Linguagraph, which is a user-friendly, clinical instrument, for measu rement of tongue/palate contact, during speech. Linguagraph allows objectiv e assessment of tongue function; appropriate targeting of therapy is theref ore possible. Visual feedback is also provided, for therapy, and an objecti ve measurement of outcome is easily obtained. Linguagraph was used, for bot h therapy and assessment, in a clinical trial. Technical aspects of Linguag raph and of the trial results are presented here. These suggest that the in strument will prove useful in the assessment and management of many speech disorders. Full clinical details of the trial are reported elsewhere. (C) 2 000 IPEM. Published by Elsevier Science Ltd. All rights reserved.
