单通道和弦音乐的旋律提取算法通常依赖于主旋律乐器的显着性，这里被认为是歌声。然而，复调中同时存在一个或多个音调乐器可能会导致这种主要的 F0 跟踪器在跟踪声音的音调和具有相当强度的乐器的音调之间切换，从而导致音调检测精度降低。我们提出了一个系统，除了偏向有利于歌声特征的显着性测量之外，还承认声音可能不会在所有瞬间主导复调音乐，因此跟踪额外的音高以更好地处理局部主导音调伴奏的潜在存在。基于语音谐波的时间不稳定性的特征用于最终识别语音音高。所提出的系统根据代表具有强音调伴奏的复调音乐的测试数据进行评估。结果表明，所提出的系统确实能够恢复单音高跟踪系统丢失的旋律信息，并且还优于另一种为复调音乐设计的最先进的旋律提取系统。
Melody extraction algorithms for single-channel polyphonic music typically rely on the salience of the lead melodic instrument, considered here to be the singing voice. However the simultaneous presence of one or more pitched instruments in the polyphony can cause such a predominant-F0 tracker to switch between tracking the pitch of the voice and that of an instrument of comparable strength, resulting in reduced voice-pitch detection accuracy. We propose a system that, in addition to biasing the salience measure in favor of singing voice characteristics, acknowledges that the voice may not dominate the polyphony at all instants and therefore tracks an additional pitch to better deal with the potential presence of locally dominant pitched accompaniment. A feature based on the temporal instability of voice harmonics is used to finally identify the voice pitch. The proposed system is evaluated on test data that is representative of polyphonic music with strong pitched accompaniment. Results show that the proposed system is indeed able to recover melodic information lost to its single-pitch tracking counterpart, and also outperforms another state-of-the-art melody extraction system designed for polyphonic music.
