Abstract:
A prosodic control method, used in speech synthesis for computing prosodic parameters for input text data and producing synthesized speech by using the computed prosodic parameter, the method comprising the steps of:providing a speech corpus storing a plurality of sets of prosodic parameters, each set based on human vocalization of plural word text data, and a plurality of sample text data sets respectively associated with the sets of prosodic parameters; comparing the input text data as a set of words with the plurality of sample text data sets stored in the speech corpus sequentially; selecting a similar prosody sample text data set from the speech corpus based upon the results of the step of comparing; acquiring prosodic parameters for any non-matched portions between the selected text data set and the input text data set; and computing each prosodic parameter for a matched portion between the selected text data set and the input text data set, and computing each prosodic parameter for any non-matched portion.
