An experimental Dutch keyboard-to-speech system has been developed to explor the possibilities and limitations of Dutch speech synthesis in a communication aid for the speech impaired. The system uses diphones and a formant synthesizer chip for speech synthesis. Input to the system is in pseudo-phonetic notation. Intonation contours using a declination line and various rises and falls are generated starting from an input consisting of punctuation and accent marks. The hardware design has resulted in a small, portable and battery-powered device. A short evaluation with users has been carried out, which has shown possibilities for such a device but has also indicated some problems with the current pseudo-phonetic input
