This paper describes the development of SNORS+, a clinical, user-friendly instrument for measurement of the articulators during speech. The design criteria for the instrument were based upon a wide-ranging review of current practice and available techniques. SNORS+ allows objective assessment of the function and co-ordination of key articulators. Appropriate targeting of therapy is therefore possible. Visual feedback is provided, for therapy, and an objective measurement of outcome is easily obtained. Preliminary results are presented. These suggest that the instrument will prove extremely useful in the assessment and management of many speech disorders.
