人类婴儿的发声在第一年经历了戏剧性的变化，变得越来越成熟和像说话一样。人类发声能力的发展部分依赖于通过婴儿和看护者之间的社会反馈进行模仿的学习。最近的研究表明，绒猴的先天发声也受到父母反馈的影响。绒猴产生婴儿特有的发声，在出生后的第一个月后消失。然而，目前还不清楚父母的反馈是否是正确的声乐发展的必要条件。使用定量的措施来比较呼叫参数和声乐序列结构，我们表明，在正常提出的绒猴，绒猴出生后第三个月后，从父母分离仍然产生婴儿特定的声乐行为在亚成年阶段。这些研究结果表明，社会反馈对灵长类动物的声音发展，直到亚成体阶段的重要作用，并进一步表明，绒猴是一个引人注目的模型系统，早期人类的声音发展。在许多动物中，成熟的声音模式的发展是由父母的影响形成的。在这里，Gultekin和Hage表明，父母的反馈不仅影响声音的发展，但确实是必要的少年绒猴获得正常的声音行为。
Vocalizations of human infants undergo dramatic changes across the first year by becoming increasingly mature and speech-like. Human vocal development is partially dependent on learning by imitation through social feedback between infants and caregivers. Recent studies revealed similar developmental processes being influenced by parental feedback in marmoset monkeys for apparently innate vocalizations. Marmosets produce infant-specific vocalizations that disappear after the first postnatal months. However, it is yet unclear whether parental feedback is an obligate requirement for proper vocal development. Using quantitative measures to compare call parameters and vocal sequence structure we show that, in contrast to normally raised marmosets, marmosets that were separated from parents after the third postnatal month still produced infant-specific vocal behaviour at subadult stages. These findings suggest a significant role of social feedback on primate vocal development until the subadult stages and further show that marmoset monkeys are a compelling model system for early human vocal development. The development of mature vocal patterns is shaped by parental influence in many animals. Here, Gultekin and Hage show that parental feedback not only influences vocal development, but is indeed necessary for juvenile marmosets to acquire normal vocal behaviour.
