人声颤音通常被认为是频率、振幅和音色（频谱）调制的结果。声音颤音发声的声学特性一直是广泛研究的主题[多伊奇]。1982年的第一次;大型，1980年; Seashore和蒂芬，1932;怀克，1974; Vcnnard，1967]，振幅或强度（I 0）调制的重要性及其与基频（Fq）调制的相位关系尚未阐明。例如，Luchsinger和Arnold [1965，p. 93]描述了F（）和lu调制之间的相位关系，但未能解释所观察到的关系的可能原因;通过同时记录音高和强度调制与颤音，可以表明，这两个参数的声乐颤音可能是相关的，在同一个颤音相位或可能是对立的。这意味着每个颤音阶段的音高上升可能与折痕的强度一致。或者音调可以上升而强度福尔斯下降，反之亦然。
Vocal vibrato is generally considered to result from modulation in frequency, ampli tude and timbre (spectrum). Acoustic char acteristics of vocal vibrato phonation have been the subject of extensive investigations [Deutsch. 1982; Large, 1980; Seashore and Tiffin, 1932; Wyke, 1974; Vcnnard, 1967], The importance of amplitude or intensity (I0) modulation and its phase relationships with fundamental frequency (Fq) modula tion have not been clarified. For example, Luchsinger and Arnold [1965, p. 93] de scribed phase relationships between F () and lu modulations but failed to explain possible causes of the relationships observed; Through simultaneous recording of the pitch and intensity modulations with vibrato, it could be shown that these two parameters of vocal vibrato may be correlated in the same vibrato phase or may proceed antagonistically. This means that the rise in pitch in each vibrato phase may coincide with intensity in crease. or pitch may rise while intensity falls and vice versa.
