Pitch-matching refers to the ability to vocally reproduce an acoustic model in a corresponding tone to the presented sound. This ability, which is dependent on pitch perception ability, can vary among individuals, and some are not able to sing in the correct tune or discriminate differences between tones. To correlate pitch-matching accuracy and auditory processing in individuals without musical training. A Pitch-Matching Test (vocal reproduction of synthesized and human voice sounds) and two commercially available tests of auditory temporal processing (the Pitch Pattern Sequence Test and the Random Gap Detection Test) were administered to all participants. A total of 62 college students of both genders, aged between 18 and 35 years old, were divided into 2 groups, according to their performances in the Pitch-Matching Test (the accurate match group and the inaccurate match group). In the Pitch-Matching Test, both groups achieved better results when reproducing vocalized sounds. The accurate match group achieved a significantly higher pitch pattern sequence test performance. In the Random Gap Detection Test analysis, there were no differences between the two groups. The Pearson's chi-squared test showed a direct correlation between the Pitch-Matching Test and the Pitch Pattern Sequence Test. The findings of this study suggest the existence of a significant relationship between temporal auditory processing and pitch-matching, through which accurate pitch-matching individuals perform better in the Pitch Pattern Sequence Test. Inaccurate pitch-matching individuals may be skilled at discriminating pitch, despite their poor performance in the Pitch-Matching Test.
音高匹配是指能够用声音以与所呈现声音相对应的音调再现声学模型的能力。这种能力依赖于音高感知能力，个体之间可能存在差异，有些人无法唱出正确的曲调或辨别音调之间的差异。
为了关联未受过音乐训练的个体的音高匹配准确性和听觉处理能力。
对所有参与者进行了一项音高匹配测试（对合成声音和人声的声音进行声音再现）以及两项市售的听觉时间处理测试（音高模式序列测试和随机间隙检测测试）。总共62名年龄在18至35岁之间的男女大学生，根据他们在音高匹配测试中的表现分为两组（准确匹配组和不准确匹配组）。
在音高匹配测试中，两组在再现发声声音时都取得了更好的结果。准确匹配组在音高模式序列测试中的表现明显更高。在随机间隙检测测试分析中，两组之间没有差异。Pearson卡方检验显示音高匹配测试和音高模式序列测试之间存在直接相关性。
本研究结果表明，时间听觉处理与音高匹配之间存在显著关系，通过这种关系，音高匹配准确的个体在音高模式序列测试中表现更好。音高匹配不准确的个体尽管在音高匹配测试中表现不佳，但可能擅长辨别音高。
