检查婴儿发声模式在互动和非互动的背景下，可能有助于更好地理解早期沟通的发展。在目前的研究中，有24个婴儿-父母的二人组，婴儿的健谈显着增加时，父母的互动停止（提出了一个“静止的脸，”或SF）后，一段时间的正常互动（“面对面，”或FF）。当父母重新参与（“团聚”，或RE）时，婴儿的活泼性继续以高于FF的速率持续。此外，在SF期间，婴儿之间的发声变异性下降，这表明婴儿采用相对相似的发声速率来重新吸引父母。SF中增加健谈的模式在生命前半年的所有最常见的语音样声音类型中都可以看到（例如，全元音、准元音、尖叫、咆哮）。父母和婴儿的活力水平没有显着相关性。研究结果表明，到六个月大的时候，婴儿已经学会了他们的发声具有社会价值，而且健谈的变化会影响父母的参与。
Examination of infant vocalization patterns across interactive and noninteractive contexts may facilitate better understanding of early communication development. In the current study, with 24 infant-parent dyads, infant volubility increased significantly when parent interaction ceased (presenting a “still face,” or SF) after a period of normal interaction (“face-to-face,” or FF). Infant volubility continued at the higher rate than in FF when the parent re-engaged (“reunion,” or RE). Additionally, during SF, the variability in volubility across infants decreased, suggesting the infants adopted relatively similar rates of vocalization to re-engage the parent. The pattern of increasing volubility in SF was seen across all of the most common speech-like vocal types of the first half-year of life (e.g., full vowels, quasivowels, squeals, growls). Parent and infant volubility levels were not significantly correlated. The findings suggest that by six months of age infants have learned that their vocalizations have social value and that changes in volubility can affect parental engagement.
