A Windows-based speech aid and language learning tool for the speech impaired

Computer-based speech aids for the vocally impaired use indirect activation (e.g. iconically labelled keys) to reproduce synthetically or naturally generated vocal sounds. The user interface specification is typically complex. Current research exploits existing flexible design models for development as language learning tools that may assist the speech therapist. The aim of the author´s work has been to investigate how future speech aids might adapt to a far greater degree to the needs of the individual user. Windows based models have been developed to apply the above findings to both communication and learning tools for the vocally handicapped. The author begins by identifying the needs of the vocally handicapped and the shortcomings of existing aids. The requirements for quadriplegics are discussed together with the alternatives to keyboards. The problems and limitations of standard speech aid keyboards act as an introduction to the theme of software generated keys
