Research and development activities in the field of automatic speech processing have been relatively important in France for the past 20 years. In 1981, the Ministry of Research created the GRECO‐PRC on Man‐Machine Communication with the role of promoting and coordinating research activities in the fields of vision, natural language, and speech. This paper gives an overview of this national project which presently groups more than 40 French laboratories. First, its role, objectives, and means of action will be briefly introduced and then a description of the ongoing projects in the different fields that have been selected will be presented: (1) design, recording, and exploitation of a database of spoken French, BDSON, to be used for fundamental studies in acoustic phonetics as well as for assessment of speech recognition and synthesis systems; (2) morphological database of speech including knowledge‐based techniques; (3) man‐machine dialogue using speech; and (4) use of prosody in automatic speech recognition. The results already obtained will be presented and the future of the project will be discussed.
