| Sumario: | The illustration of complex articulatory movements is integral part of therapy for neurogenic and developmental speech disorders. Yet, PC-assisted therapy is used hardly ever in this context. The software 'Speech Trainer' (free of charge) is a new therapeutic aid that visualizes articulation and coarticulation by means of dynamic animations. First empirical evidence for the efficacy of Speech Trainer is provided by two single case studies. Regarding apraxia of speech, Speech Trainer was evaluated in therapy for a patient with severe, chronic apraxia of speech, In articulation therapy, Speech Trainer was used in the treatment of children at pre-school and school age. The evidence points to the fact that1. the animation of Speech Trainer is well understood by the participants and useful for their own speech2. Speech Trainer is an effective therapeutic aid in modelling articulatory movements.
