Vocal pitch matching is a foundational skill for singing and is an interesting place to study the relationship between pitch perception and production. To better understand this relationship, we assessed pitch-matching abilities in congenital amusics, who have documented disabilities in pitch perception, and in matched controls under normal, masked, and guided feedback conditions. Their vocal productions were analyzed for fundamental frequency and showed that amusics were significantly less accurate at pitch matching than the controls. However, five of the six amusics showed a significant correlation between their produced pitches and the target pitch. Feedback condition had no effect on pitch-matching accuracy. These results show impaired vocal pitch-matching abilities in amusics but also show a relationship between perceived and produced pitches.
音高匹配是歌唱的一项基本技能，也是研究音高感知和产生之间关系的有趣领域。为了更好地理解这种关系，我们评估了先天性失歌症患者的音高匹配能力，他们在音高感知方面有记录的障碍，以及在正常、掩蔽和引导反馈条件下的匹配对照组。对他们的声音进行了基频分析，结果表明，失歌症患者在音高匹配方面明显不如对照组准确。然而，在 6 名失歌症患者中有 5 名患者表现出其产生的音调和目标音之间存在显著相关性。反馈条件对音高匹配精度没有影响。这些结果表明失歌症患者的音高匹配能力受损，但也显示了感知音高和产生音高之间的关系。
