Segmentation and labelling of Slovenian diphone inventories

Preparation, recording, segmentation and pitch labelling of Slovenian diphone inventories are described. A special user friendly interface package was developed in order to faciliate these operations. As acquisition of a labelled diphone inventory or adaptation of a speech synthesis system to synthesise further voices is manually intensive, an automatic procedure is required. A speech recognizer, based on Hidden Markov Models in forced segmentation mode is used to outline phone boundaries withhin spoken logatoms. A statistical evaluation of manual and automatic segmentation discrepancies is performed so as to estimate the reliability of automatically derived labels. Finally, diphone boundaries are determined and pitch markers are assigned to voiced sections of the speech signal.
