DEVICE AND METHOD FOR RHYTHM CONTROL

摘要

PROBLEM TO BE SOLVED: To obtain a natural speech as a synthesis result when a speech is synthesized by combining a speech of a document different in pronunciation style and a speech of word together. SOLUTION: In addition to a data base 1 wherein speeches of various words are registered and a data base 5 wherein speeches of fixed form parts of various documents are registered, a table 3 containing registered rhythms of those words and a table 7 containing ranges of rhythms that word parts of those documents should have are prepared. The speech and rhythm of a desired word are read out and the speech of a fixed part of a desired document and the rhythm range of the word part are read out. Then the rhythm 23 of the word is compared with the rhythm range 27 of the word part of the document to calculate the difference 29 between both the rhythms. Then rhythm control 17 based upon the difference 29 is exercised over the speech 21 of the word to convert the speech 21 of the word into a speech 31 having a rhythm converging in the rhythm range 27. Then the converted word speech 31 is combined with the speech 25 of the fixed form part of the document to synthesize the speech 33 of the complete document.
