描述了一种用于自动提取可能由复杂音调刺激同时诱发的各种基音感知的过程。该过程基于虚拟音调的理论，特别是基于这样的原理，即整个音调感知既依赖于分析倾听(产生频谱音调)，也依赖于整体感知(产生虚拟音调)。由这两种基音模式控制的或多或少模糊的基音感知由两种基音模式描述：频谱基音模式和虚拟基音模式。这些模式中的每一种都由许多螺距(高度)值和相关权重组成，这些值说明了每个单独螺距的相对突出程度。通过频谱分析、提取声调成分、评估掩蔽效果(掩蔽和基音漂移)以及根据频谱优势原则进行加权，构建了频谱-基音模式。从频谱节距模式中通过改进的谱节距模式获得虚节距模式.
A procedure is described for the automatic extraction of the various pitch percepts which may be simultaneously evoked by complex tonal stimuli. The procedure is based on the theory of virtual pitch, and in particular on the principle, that the whole pitch percept is dependent both on analytic listening (yielding spectral pitch), and on holistic perception (yielding virtual pitch). The more or less ambiguous pitch percept governed by these two pitch modes is described by two pitch patterns: the spectral‐pitch pattern, and the virtual‐pitch pattern. Each of these patterns consists of a number of pitch (height) values, and associated weights, which account for the relative prominence of every individual pitch. The spectral‐pitch pattern is constructed by spectral analysis, extraction of tonal components, evaluation of masking effects (masking and pitch shifts), and weighting according to the principle of spectral dominance. The virtual‐pitch pattern is obtained from the spectral‐pitch pattern by an advanced...
