| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Speech databases with accurate phoneme labeling are often required to improve speech technologies. Although HMM-based forced alignment is widely used, the performance easily decreases when the input speech data has a different speaking style from that of the speech data used for training HMMs. An alternative is a speech segmentation method only based on acoustic analysis. For example, the speech segmentation based on measuring spectral transition was proposed previously. In this report, another analysis-based method is proposed which uses constrained clustering on a time series of frames. Some discussions will be done on estimation of the number of phonemes and detection of mora boundaries. Finally, by comparing the phoneme boundary detection performance between the previous method and the proposed method, the higher robustness of our proposal is shown. |
