在婴儿咿呀学语的规范阶段，婴儿发出结构良好的音节，通常是重复的序列，如“巴巴巴”。“虽然几乎所有听力正常的婴儿开始典型阶段的10个月大，少数延迟，这些婴儿可能是特别感兴趣的。最近的研究表明，迟发的典型的咿呀学语可能是一个预测的障碍。一个简单的筛查程序，重点是规范的咿呀学语，被用来评估超过3400名婴儿的风险谁是约10个月大。在那些出现典型的咿呀学语的婴儿中，只有不到一半的人以前被诊断出患有严重的医学问题，这可能是导致延迟的原因。一项后续研究表明，与对照组的婴儿相比，具有延迟的规范性牙牙学语的婴儿在18个月、24个月和30个月时的产出词汇量较小。结果表明，迟发的典型咿呀学语，一个因素，可以有效地通过与父母的访谈进行监测，可以预测延迟的言语产生的发病。(C)1999年，Elsevier Science Inc.
During the canonical stage of infant babbling, infants produce well-formed syllables, often in reduplicated sequences such as "bababa." Although nearly all infants with normal hearing begin the canonical stage by 10 months of age, a few are delayed, and these infants may be of special interest. Recent studies indicate that late onset of canonical babbling may be a predictor of disorders. A simple screening procedure that focuses on canonical babbling was used to evaluate over 3400 infants at risk who were about 10 months of age. Among infants who showed late onset of canonical babbling, fewer than half had been previously diagnosed as having a significant medical problem that might have accounted for the delay. A follow-up study indicated that infants with delayed canonical babbling had smaller production vocabularies at 18, 24, and 30 months than did infants in the control group. The results suggest that late onset of canonical babbling, a factor that can be monitored effectively through an interview with a parent, can predict delay in the onset of speech production.
