抄録

We developed a method which used decision lists for partial dependency analysis which was important for a pause control of a speech synthesis. As the result of its evaluation using F measure as the accuracy of pause insertions, it was 90.04%.This method based on decision lists has a good point about flexibility adjusting the memory usage and the processing speed.In the case of small 12K Bytes memory and high speed, the processing time to set pauses of a sentence is 7msec (Pentium III 450MHz) and F measure is 85%. These results indicate that this method is applicable for the actual speech synthesis systems. We made rules for pause insertions and confirmed the performance by subjective evaluations. As the result, the appropriate rate was about 85% by the control derived only by dependency distances and the appropriate rate was about 91% by the control derived additional factors such as punctuation marks and succession of pauses.
