In this paper we describe a new method, in automatic speaker recognition, based on modified LVQ1 (MLVQ1) and using 3 prosodic features: the mean of the pitch, the original duration and the low-frequency energy. For this purpose, we conceived a new metric, optimized in automatic speaker recognition, which we called ODHEF. The tests of speaker recognition are done in Arabic corpus with 2 different sets: a closed set and an open set. The results show that the prosodic features are relevant and that the modified LVQ1 (MLVQ1) method is interesting in text-dependent speaker identification.
