Ackermann et al. briefly point out the potential significance of coordinated vocal behavior in the dual pathway model of acoustic communication. Rhythmically entrained and articulated pre-linguistic vocal activity in early hominins might have set the evolutionary stage for later refinements that manifest in modern humans as language-based conversational turn-taking, joint music-making, and other behaviors associated with prosociality.
阿克曼等人简要指出了协调发声行为在声学通讯双通道模型中的潜在意义。早期人类中具有节奏性和协调性的前语言发声活动可能为后来的进化阶段奠定了基础，这些进化阶段在现代人中表现为基于语言的对话轮流、共同作曲以及与亲社会行为相关的其他行为。
