Kali, a French-speaking text-to-speech synthesis software package created for visually handicapped people, is the result of a collaboration between University and the private sector. The input text goes through a succession of 5 modules (preprocessing, syntactic analysis, prosodic gene-ration, phonemisation, acoustico-phonetic processing) and is then pronounced. Its best feature is intelligibility at rapid delivery. In this paper, prosodic processing is presented from the phonological representation of intonation to the acoustic processing.
