A speech therapy workstation is under development for the purpose of supervised rehabilitation of oral cancer patients. The design of this workstation differs from that of most others of this type in three ways. Firstly, the software is designed to address the problems of this specific patient group. Secondly, patients and therapists are involved throughout the design process at the earliest opportunity. Thirdly, the project is based on advances in automated acoustic phonetic analysis which overcome many of the problems associated with formant analysis of voiceless fricatives and in so doing provide intuitive visual feedback for this category comparable to the F1/F2 plots for vowels. This paper discusses the constraints placed on the design of such a workstation, the solutions and the acceptability of the resulting system.
