到了10个月大的时候，发育中的婴儿通常会发出规范的牙牙学语，其中包括有意义的语言所需的良好音节。研究表明，新出现的言语或语言相关障碍可能与典型牙牙学语的晚发有关。对1，536名校正年龄约为10个月的高危婴儿进行了规范性咿呀学语发作调查。家长报告的开放式问卷被认为是一种有效的方法来确定咿呀学语的状态。虽然延迟是罕见的，他们往往与遗传，神经，解剖和/或生理异常。超过一半的晚期典型牙牙学语病例在被发现时与先前的重大医学诊断无关。晚发的典型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.
