TEXT VOICE CONVERSION METHOD AND METHOD FOR DETERMINING BREATHING POSITION OF TEXT VOICE CONVERTER

摘要

PROBLEM TO BE SOLVED: To make it possible to convert inputted sentences to natural speeches by determining breathing positions in accordance with the inputted sentences and inserting breathing tones in the determined breathing positions. SOLUTION: The speech signals formed in a speech forming section 2 is sent to a breathing and silent inserting section 3 and are sent to a breathing position candidate detecting section 5. The breathing and silent inserting section 3 inserts the breathing or silent speech signals into the speech signals formed in the speech forming section 2 according to the controlling command from the breathing and silent inserting control section 6. The speech signals obtd. by the breathing and silent inserting section 3 are outputted as speeches via a speech output section 4. The breaching position candidate detecting section 5 accumulates the power values of the speeches from the speech signals formed by the speech forming section 2 and sends breaching position information to a breathing and silent insertion control section 6 when the cumulative value attains the prescribed value determined beforehand. The control section clears the cumulative value thus far and freshly starts the accumulation.
