Evaluation of a prosodic labeling system utilizing linguistic information

A prosodic labeling support system has been developed and evaluated. Large-scale prosodic databases are strongly desired for years, however, the construction of databases depend on hand labeling, because of diversity of prosody. We aim at not automating the whole labeling process, but making the hand labeling work more efficient by providing labelers with appropriate support information. A method to generate J-ToBI labels utilizing linguistic information had been already proposed. We have developed a J-ToBI labeling system using initial labels generated by the proposed method, and conducted labeling experiments using the system. Records of the labeling work in the experiments proved that time required to do the labeling work was reduced to half by using the system with the initial labels. Subjective evaluation results also verified the validity of the proposed method to support the labeling work.
