SICOLE is a research effort to develop a software environment to help tutors of dyslexic children with the diagnostic and treatment tasks. This paper describes the architecture of the package already implemented where three important elements interact: a multimedia interface, an inference module and a database. This architecture provides the system with the flexibility to support a large variety of tasks, dynamic presentations, and complex teaching strategies. The application of speech recognition technology is also researched as an important part of the evaluation of the dyslexic children improvements. This package is being used at the present moment in several Spanish Schools as part of its validation process.
