Abstract

Vicent Tamarit, Carlos D. Martínez-Hinarejos. Dialog act labeling in the DIHANA corpus using prosody information. V Jornadas en Tecnologías del Habla (VJTH'2008), 2008. pp. 183-186.

We propose a dialog act classification based on the prosody of the audio signal in combination with the course of the dialog. The work is applied to the Spanish corpus DIHANA. As far as we know, it is the first experiment made with prosody in this corpus. To do the labeling, we used two features that had been extracted from the user speech (pitch and energy) in a HMM classifier combined with an n-gram of dialog acts. The results shows a sightly improvement in the tagging when prosody is included in the classification.
