The objective of this work is to disambiguate transducers which have the following form: T = R D and to be able to apply the determinization algorithm described in (Mohri, 1997). Our approach to disambiguating T = R D consists rst of computing the composition T and thereafter to disambiguate the transducer T. We will give an important consequence of this result that allows us to compose any number of transducers R with the transducer D, in contrast to the previous approach which consisted in rst disambiguating transducers D and R to produce respectively D0 and R0, then computing T0 = R0 D0 where T0 is unambiguous. We will present results in the case of a transducer D representing a dictionary and R representing phonological rules. Keywords: ambiguity, determinis- tic, dictionary, transduce...
