A hierarchical intonation model for synthesising F0 contours in galician language

Xavier Fernández-Salgado, Eduardo R. Banga

In this contribution we propose a hierarchical intonation model for synthesising f0 contours with application to text-to-speech synthesis in Galician language. This model makes use of the implicit knowledge that resides in a database of natural f0 contours obtained from a read corpus. The novelty of this method lies on the way the f0 contour is generated. First, no phonological description in terms of a sequence of tones is needed prior to f0 generation. The phrasing obtained from previous stages of the TTS system is enough for this task. Second, the final f0 contour is built through several steps that assign patterns at the phonic group level (intonational phrase), the tonic group level and the segmental level following a hierarchical method. The proposed algorithm guarantees a coherent concatenation of the patterns that belong to different levels, and it seems to work properly as a general intonation model for a wide range of sentence modalities.
