In this paper we propose a strategy to improve the performance of a connected number recognition system in Spanish using prosodic information. Prosodic information is included as the detection of pitch movements between what some studies of intonation in Spanish called melodic units. The basic linguistic background of our approach together with the specific strategies to detect and correct ambiguities and recognition errors are discussed. Experimental results show a 16% of reduction in recognition errors for our state-of-the-art connected number recognizer, and the possibility to solve ambiguities unable to be considered by the recognizer.
