Prophon is an interactive environment for developing applications and conducting research in text-to-speech conversion. The environment, which is written in the programming language Prolog, can be considered as a shell for developing knowledge based systems. It is created specifically for the linguistic domain and encourages an incremental development of text-to-speech systems. Prophon offers a rich set of tools for creating rules at different levels.
