摘要： A match score provides a semantically-meaningful quantification of the aural similarity of two chromae from two corresponding audio sequences. The match score can be applied to the chroma pairs of two corresponding audio sequences, and is independent of the lengths of the sequences, thereby permitting comparisons of matches across subsequences of different length. Accordingly, a single cutoff match score to identify "good" audio subsequence matches can be determined and has both good precision and good recall metrics. A function for determining the match score is determined by establishing a function P M indicating probabilities that chroma correspondence scores indicate semantic correspondences, and a function P R indicating probabilities that chroma correspondence scores indicate random correspondences, repeatedly updating P M and the match function based on existing values of P M and the match function as applied to audio subsequences with known semantic correspondences.
摘要翻译：匹配分数从两个对应的音频序列提供两个色度的听觉相似性的语义上有意义的量化。匹配分数可以应用于两个对应的音频序列的色度对，并且与序列的长度无关，从而允许比较不同长度的子序列的匹配。因此，可以确定用于识别“良好”音频子序列匹配的单个截止匹配分数，并且具有良好的精度和良好的回忆度量。通过建立指示色度对应分数表示语义对应关系的概率的函数PM和表示色度对应分数表示随机对应关系的概率的功能PR，根据现有的值的重复更新PM和匹配函数来确定匹配分数的功能 PM和匹配功能应用于具有已知语义对应关系的音频子序列。
