言语通常伴随着许多身体动作，如手势、点头、改变姿势等。众所周知，这些动作具有交际和调节功能，如澄清或强调信息，调节话轮等。此外，与此平行的是，身体动作具有特定的言语产生功能，主要是促进词汇选择和调节韵律特征。服务于这两个功能的动作在许多方面不同，例如，在它们的运动学特性、复杂性、与语音有关的定时、失语症的损害、编码模式和它们产生的语音处理的阶段。这些差异是突然出现的，而不是指令性的或受规则控制的，源于认知和运动限制。身体运动的功能利用在当地是可选的。
Speech is normally accompanied by numerous body movements such as hand gestures, head nods, posture changes, etc. These are known to have communicative and regulatory functions such as clarifying or emphasising messages, regulating speaking turns, etc. In addition and in parallel to these, it is argued, body movements have specific speech productive functions, primarily the facilitation of lexical selection and the regulation of prosodic features. Movements serving the two functions differ in many ways, e.g. in their kinematic properties, complexity, timing in relation to speech, impairment in aphasia, mode of encoding and the stages of speech processing in which they originate. These differences are emergent, rather than prescriptive or rule-governed, originating in cognitive and motor constraints. The functional utilisation of body movement is locally optional.
