A Formal Tool for Modelling "Standard" Phonetic Variations

Speech processing requires that some more phonetic variability than in current systems should be taken into account. CERIL has undertaken the description of a category of variability. In this paper, we discuss the limits of this description in terms of its extent (which styles are retained and which are discarded?) and of its precision (which minimal difference between two variants can be taken into account?). Then we present the formal and technical means used to model phonetic variations: a phonemic dictionary and local finite-state automata.
