Abstract

(eng) The automatic recognition of spoken words is increasingly common, for dictaphone applications, telephone services or the command of various devices by disabled persons. In the latter case, a high recognition rate is expected on a vocabulary of small to medium size. To achieve this goal, the model must be refined. Thus, both the training stage and the recognition stage for such applications can be very time consuming and occasional re-training may happen. Its parallelization is thus worth considering. In this paper we present firstly the models we use: the classical hidden Markov model and another model that takes into account the prosody of speech, namely the centisecond two-level hidden Markov model introduced by Meziane. Then two parallelization strategies are detailed: the first one simply shares the vocabulary among the processors, the second one also distributes the model. %which has to be slightly modified in order to allow this distribution. Experimental results highlight the need for a finer load-balancing: an
