Performances of an automatic speech recognition system degrade when test and training conditions do not match. Classical Stochastic Matching (SM) method proposes an off-line estimation of a compensation function that maximizes the likelihood of the compensated speech, given the optimal sequence of models proposed by the recognition process. We developed a new frame-synchronous technic based on SM : compensation is performed in parallel with the recognition. This is suitable to cope with slowly varying noise. We proposed two additional versions of our approach: -a tree structure of transformations is used to build a state-dependant non-linear compensation function. This is motivated by the fact that similar observations will be affected simi...
