In this paper we present a system designed by VECSYS, in collaboration with LIMSI, to generate and synthesize high quality broadcast messages. The system is currently under-going evaluation tests to automatically generate and broadcast messages about weather and airport conditions. The generated messages are alternately broadcast in French and in English.

This paper focuses on the synthesis aspects of the system which synthesizes messages by concatenation of speech units stored in the form of a dictionary. The texts corresponding to the messages to be synthesized and broadcast are automatically generated by a server, and transmitted to the synthesis component. Should the system be unable to generate the message from existing entries in the dictionary, the system permits a human operator to record the message which is subsequently broadcast.
