Algorithms on Transducers



Transducers are used in many contexts, such as speech recognition or in order to measure the similarity between proteins. This research shows the implementation in Vcsn of several algorithms allowing to manipulate the transducersand thus solve these problems. First an algorithm to transform a transducer into a weighted automaton that can be easily evaluated is presented. The synchronization algorithm was then implemented, leading to the computation of the edit-distance transducer and its evaluation.
