声音合成方法、声音合成装置和存储声音合成程序的介质
摘要：
本发明提供了声音合成方法、声音合成装置和存储声音合成程序的介质。一种声音合成方法，用于通过提取自参考声音的语音片段的连接而产生声音信号，所述方法包括：由片段选择单元顺序地选择所述语音片段；由音高设置单元设置音高过渡，在所述音高过渡中，根据与作为所述参考声音的声产生参考的参考音高和所述片段选择单元所选择的语音片段的观测音高之间的差值相对应的音级，来反映所述语音片段的观测音高的变动；以及由声音合成单元通过根据所述音高设置单元所产生的音高过渡而调整所述片段选择单元所选择的语音片段的音高，来产生所述声音信号。
摘要（英）：

A voice synthesis method for generating a voice signal through connection of a phonetic piece extracted from a reference voice, includes selecting, by a piece selection unit, the phonetic piece sequentially; setting, by a pitch setting unit, a pitch transition in which a fluctuation of an observed pitch of the phonetic piece is reflected based on a degree corresponding to a difference value between a reference pitch being a reference of sound generation of the reference voice and the observed pitch of the phonetic piece selected by the piece selection unit; and generating, by a voice synthesis unit, the voice signal by adjusting a pitch of the phonetic piece selected by the piece selection unit based on the pitch transition generated by the pitch setting unit.
