为了用日语文语转换系统合成更自然的语音，我们改进了口音连读规则。传统的日语连读变调规则缺乏与数词和反义词相关的规则。本文针对日语口音词典中有关词语组合的口音规则，对日语口音词典中有关数词和反义词的口音规则进行了全面的改进。然后，使用传统和改进的规则进行口音估计实验，以评估两种类型的规则的估计的准确性。通过对实验结果的分析，讨论了重音连读变调规则本身和改进规则的有效性和存在的问题。
In order to synthesize more natural speech with Japanese text-to-speech systems, we improve accent sandhi rules. The conventional Japanese accent sandhi rules lack rules related to numerals and counter words in conventional rules. In this paper, we comprehensively improved the accent sandhi rules as well as those related to numerals and counter words, concerning accent rules related to word combinations described in the Japanese accent dictionaries. Then, accent estimation experiments were conducted using the conventional and improved rules to evaluate the accuracy of the estimation by the two types of rules. The effectiveness and problems of the accent sandhi rules themselves and improved rules were discussed by analyzing the experimental results.
