    • A speech unit corpus stores a group of speech units. A selection unit divides a phoneme sequence of target speech into a plurality of segments, and selects a combination of speech units for each segment from the speech unit corpus. An estimation unit estimates a distortion between the target speech and synthesized speech generated by fusing each speech unit of the combination for each segment. The selection unit recursively selects the combination of speech units for each segment based on the distortion. A fusion unit generates a new speech unit for each segment by fusing each speech unit of the combination selected for each segment. A concatenation unit generates synthesized speech by concatenating the new speech unit for each segment.
    • 语音单元语料库存储一组语音单元。 选择单元将目标语音的音素序列划分为多个段,并且从语音单元语料库中选择每个段的语音单元的组合。 估计单元通过对每个段的组合的每个语音单元进行融合来估计目标语音和合成语音之间的失真。 选择单元基于失真递归地选择每个段的语音单元的组合。 融合单元通过融合为每个段选择的组合的每个语音单元,为每个段生成新的语音单元。 级联单元通过连接每个段的新语音单元产生合成语音。
