摘要

This paper proposes a modified Tilt model, called T-Tilt, for analyzing and synthesizing FO contours in tonal languages. The Tilt model successfully designed for intonation modeling is extended to cover syllable-based FO realization influenced strongly by the tonal context. Two modification approaches include adding a parameter indicating a FO curve pattern and separating duration and amplitude controls inherent in the Tilt parameter for sake of flexibility. Evaluations are conducted by both an objective RMSE measure and a subjective MOS test on intelligibility and naturalness aspects. Applying to Thai and Mandarin Chinese continuous speech, the proposed model is proved to be very effective for FO contour analysis. It rather requires extensive work on parameter synthesis although the synthesizing performance is comparable to those produced by other proposed models.
