Abstract
The automatic segmentation and parametrization based on the frequency analysis was used to compare with manually annotated phones. The phones boundaries were fixed in places of relatively large changes in the energy distribution between the frequency bands. Frequency parametrization and clustering enabled the division of phones into groups (clusters) according to their acoustic similarities. The results of performed experiments showed that analysis of the frequency properties only, results in correct segmentation but accuracy of recognition was about 20% only.
