PROBLEM TO BE SOLVED: To provide a voice synthesis device capable of generating a synthetic voice having a stable rhythm close to a natural voice.SOLUTION: A voice synthesis device 1 includes: approximate pitch pattern output means 11 for inputting a pitch pattern including a fine structure, and for generating an approximate pitch pattern for approximately expressing the pitch pattern; and pitch pattern connection means 12 for inputting an original utterance pitch pattern based on the registered pitch pattern and the approximate pitch pattern, and for determining a connection point between the pitch pattern including the fine structure and the original utterance pitch pattern on the basis of the approximate pitch pattern, and for connecting the pitch pattern including the fine structure with the original utterance pitch pattern at the connection point to generate a connected pitch pattern. |
