The French website
MSX Café has published an MSX utility of over 20 years old, made by French MSX users Patrice Auffret, Frédéric Hartard and Henri Frere. This program from 1987 converts given text to French speech using the Philips Music module. It reproduces words using 30 phonemes, and the result can afterwards be used in BASIC!
