We show that the human voice has complex acoustic qualities that are directly coupled to peripheral musculoskeletal tensioning of the body, such as subtle wrist movements. In this study, human vocalizers produced a steady-state vocalization while rhythmically moving the wrist or the arm at different tempos. Although listeners could only hear and not see the vocalizer, they were able to completely synchronize their own rhythmic wrist or arm movement with the movement of the vocalizer which they perceived in the voice acoustics. This study corroborates recent evidence suggesting that the human voice is constrained by bodily tensioning affecting the respiratory-vocal system. The current results show that the human voice contains a bodily imprint that is directly informative for the interpersonal perception of another's dynamic physical states.
我们表明，人类的声音具有复杂的音响特质，这些特质与身体的外围肌肉骨骼张力直接相关，例如微妙的手腕运动。在这项研究中，人类发声者在以不同的节奏移动手腕或手臂时发出稳定的发声。尽管听众只能听到而不能看到发声者，但他们能够完全将自己的节奏手腕或手臂运动与他们在声音音响中感知到的发声者的运动同步。这项研究证实了最近的证据，即人类的声音受到影响呼吸-发声系统的身体紧张的限制。当前的结果表明，人类的声音包含一个身体印记，对于人际感知他人的动态身体状态具有直接的信息性。
