The SPECO Project was funded by the EU through the INCOCOPERNICUS program (Contract no. 977126) in 1999. In the frame of the project a system has been developed which is an audio-visual pronunciation teaching and training system for 5-10 year old children. Correction of disordered aspects of speech is done by real time visual presentation of the speech parameters, in a way that is understandable and interesting for young children, while remaining correct from the acoustic-phonetic point of view. The development of the speech by our teaching method is made mainly on the basis of visual information using the intact visual channel of the hearing impaired child. However during practice we use their limited auditory channel too, by giving auditory information synchronised with the visual one. This multi modal training and teaching system has been developed for languages of all the SPECO partners; these are English, Swedish, Slovenian and Hungarian.
