Quantitative F0 pattern generation device and method, model learning device for F0 pattern generation, and computer program

摘要

[Object] An object is to provide an F0 contour synthesizing device based on statistic model, to clarify correspondence between linguistic information and F0 contour while maintaining accuracy. [Solution] An HMM learning device includes: a parameter estimating unit representing an F0 contour 133 fitting a continuous F0 contour 132 as a sum of phrase components and accent components and estimating target points of these; and an HMM learning means conducting learning of HMM 139 using the fitted F0 contour as training data. The continuous F0 contour may be decomposed to accent components 134, phrase components 136 and micro-prosody components 138, and separate HMMs 140, 142 and 144 may be trained. Using results of text analysis, accent components, phrase components and micro-prosody components are separately synthesized from HMMs 140, 142 and 144 and the results are synthesized to obtain an F0 contour.
