在这项研究中，我们调查了先天性失忆，一种音乐加工障碍，对说声调语言普通话的人的言语和歌曲模仿的影响。一组13名说普通话的先天性失明个体和13名匹配的对照组被记录下来，同时模仿一组不同音调和节奏的语音和两组歌曲刺激。结果表明，无论是在音高匹配(绝对匹配还是相对匹配)和节奏匹配(相对时间和时间错误数)方面，先天性失语症患者的语音和歌曲模仿都比对照组差。与对照组一样，先天失语症患者在歌曲中的绝对和相对音调匹配效果更好，音调间隔和轮廓错误也比语音模仿时更少。这些发现指出先天失忆症的音高(和时间)产生缺陷，这表明存在共同的音高产生机制，但在语言和音乐处理中对音高匹配的准确性有不同的要求。
In this study, we investigated the impact of congenital amusia, a disorder of musical processing, on speech and song imitation in speakers of a tone language, Mandarin. A group of 13 Mandarin-speaking individuals with congenital amusia and 13 matched controls were recorded while imitating a set of speech and two sets of song stimuli with varying pitch and rhythm patterns. The results indicated that individuals with congenital amusia were worse than controls in both speech and song imitation, in terms of both pitch matching (absolute and relative) and rhythm matching (relative time and number of time errors). Like the controls, individuals with congenital amusia achieved better absolute and relative pitch matching and made fewer pitch interval and contour errors in song than in speech imitation. These findings point toward domain-general pitch (and time) production deficits in congenital amusia, suggesting the presence of shared pitch production mechanisms but distinct requirements for pitch-matching accuracy in language and music processing.
