到了生命的第 10 个月，正常发育的婴儿就会开始发出规范的牙牙学语，其中包括有意义的言语所需的结构良好的音节。研究表明，新出现的言语或语言相关障碍可能与规范牙牙学语的迟发有关。对 1,536 名校正年龄约为 10 个月的高危婴儿进行了标准牙牙学语的研究。通过开放式问卷调查得出的家长报告被认为是确定牙牙学语状况的有效方法。尽管延迟并不常见，但它们通常与遗传、神经、解剖和/或生理异常有关。超过一半的晚期规范胡言乱语在被发现时与之前的重大医疗诊断有关。较晚出现的规范性牙牙学语可能预示着以后的发育障碍，包括言语、语言和阅读方面的问题。
By their 10th month of life, typically developing infants produce canonical babbling, which includes the well-formed syllables required for meaningful speech. Research suggests that emerging speech or language-related disorders might be associated with late onset of canonical babbling. Onset of canonical babbling was investigated for 1,536 high-risk infants, at about 10-months corrected age. Parental report by open-ended questionnaire was found to be an efficient method for ascertaining babbling status. Although delays were infrequent, they were often associated with genetic, neurological, anatomical, and/or physiological abnormalities. Over half the cases of late canonical babbling were not, at the time they were discovered associated with prior significant medical diagnoses. Late canonical-babbling onset may be a predictor of later developmental disabilities, including problems in speech, language, and reading.
