| 摘要该文使用音高映射方法，通过选择合适的标准语音，合成出音段、音色保持不变，而只是声调变为标准语音声调的教学语音用于声调训练，减少了语音信号中声调信息之外的复杂变化带来的信息冗余与干扰。以汉语双字调的合成语音为实验材料，对日本被试进行了声调训练实验。训练结果表明：合成语音方法在声调的感知和产出的相对进步率，以及泛化产出的效果上都优于标准语音方法，远好于没有训练的对照组，大部分实验结果差异在统计上具有显著性。实验结果佐证了语音学习时存在人脑的选择性注意机制，为将合成语音方法集成到计算机辅助汉语声调教学系统，提供了实验和理论依据。 |

| Abstract：This study uses the pitch projection method to synthesize teaching speech with the appropriate standard voice. The teaching speech is synthesized by turning lexicon tones in the learners' speech into standard tones, while keeping the segments and timbie unchanged. This simplifies the complex variations in the speech signal except for the tones. Then, the system is used for tone training Japanese students based on the synthesized Mandarin two-syllable words. The training results show that this synthesized speech method is superior to a standard voice method with improved perception and production, as well as generalized production. The training results for the synthesized speech method are far better than a control group without training. Most of the results are statistically significant. Tests also show the existence of a selective attention mechanism in the human brain when learning speech. Thus, this study provides an experimental and theoretical basis for speech synthesized methods to be integrated into computer-assisted Mandarin tone learning systems. |
