提出了一套改进的声调连接规则，用于基于共振峰的汉语文本到语音系统。该系统将预先存储的音节与附加的音调模式叠加在一起，以获得无限文本的语音句子，每个音节的声学特性通过一组合成规则进行修改。在这些合成规则中，声调连接规则是最重要的，因为它告诉我们在任意句子中，在不同声调的音节连接的各种条件下，音节的声调模式应该如何改变。通过仔细分析数据库中多个句子在不同声调连接条件下的声调模式行为，得出了改进的声调连接规则。五音共定义了14种具有代表性的调式，并详细组织了在何种调式连接条件下应使用何种调式的不同规则。初步的主观测试表明，这些规则实际上为基于共振峰的中文文本到语音系统提供了更好的合成语音。>
A set of improved tone concatenation rules to be used in a formant-based Mandarin Chinese text-to-speech system is presented. This system concatenates prestored syllables superimposed by additional tone patterns to obtain speech sentences for unlimited text, with the acoustic properties of each syllable modified by a set of synthesis rules. The tone concatenation rules are the most important among these synthesis rules, because they tell how the tone patterns for the syllables should be modified in an arbitrary sentence under various conditions of concatenating syllables of different tones on both sides. The improved tone concatenation rules are obtained empirically by carefully analyzing the tone pattern behavior under various tone concatenation conditions for many sentences in a database. A total of 14 representative tone patterns are defined for the five tones, and different rules about which pattern should be used under what kind of tone concatenation conditions are organized in detail. Preliminary subjective tests indicate that these rules actually give better synthesized speech for a formant-based Chinese text-to-speech system. >
