摘要
The present invention provides a method and apparatus for training a duration prediction model, method and apparatus for duration prediction and method and apparatus for speech synthesis. Said method for training a duration prediction model and comprising: generating an initial duration prediction model with a plurality of attributes related to duration prediction and at least part of possible attribute combinations of said plurality of attributes and in which each of said plurality of attributes and said attribute combinations is included as an item; calculating importance of each said item in said duration prediction model; deleting the item having the lowest importance calculated; re-generating a duration prediction model with the remaining items; determining whether said re-generated duration prediction model is an optimal model; and repeating said step of calculating importance and the following steps and if said duration prediction model is determined as not optimal model.
