| Popis: | International audience; In this paper, a method for prosodic break modelling based on segmental-HMMs and Dempster-Shafer fusion is presented, and the relative importance of linguistic and metric constraints in prosodic break modelling is assessed. A context-dependent segmental-HMM is used to explicitly model the linguistic and the metric constraints. Dempster-Shafer fusion is used to balance the relative importance of the linguistic and the metric constraints into the segmental-HMM. A linguistic processing chain based on surface and deep syntactic parsing is additionally used to extract linguistic informations of different nature. An objective evaluation proved evidence that the optimal combination of the linguistic and the metric constraints significantly outperforms both the conventional HMM (linguistic information only) and segmental-HMM (equal balance of linguistic and metric constraints), and confirmed that the linguistic constraint is prior to the metric. |
