Read symbol string editing apparatus and reading symbol string editing method

摘要

PROBLEM TO BE SOLVED: To provide a reading symbol string editing device for shortening a time required to edit reading symbol strings and securing the quality of edited voice waveforms.SOLUTION: According to an embodiment, the reading symbol string editing device includes language processing means for generating a reading symbol string, reading symbol string storage means for storing the reading symbol string, first voice synthesis means for converting the reading symbol string of the reading symbol string storage means into a first voice waveform, second voice synthesis means for converting the reading symbol string of the reading symbol storage means into a second voice waveform, and reading symbol string editing means for using the second voice synthesis means to edit at least an accent type of the reading symbol string of the reading symbol string storage means. A processing time of the second voice synthesis means is shorter than a processing time of the first voice synthesis means, or an utterance speed of the second voice waveform converted by the second voice synthesis means is different from an utterance speed of the first voice waveform converted by the first voice synthesis means.SELECTED DRAWING: Figure 1
