PURPOSE OF REVIEW
To summarize findings about the emergence and characteristics of canonical babbling in children with late detected developmental disorders (LDDDs), such as autism spectrum disorder, Rett syndrome, and fragile X syndrome. In particular, we ask whether infants' vocal development in the first year of life contains any markers that may contribute to earlier detection of these disorders.
RECENT FINDINGS
Only a handful studies have investigated canonical babbling in infants with LDDDs. With divergent research paradigms and definitions applied, findings on the onset and characteristics of canonical babbling are inconsistent and difficult to compare. Infants with LDDDs showed reduced likelihood to produce canonical babbling vocalizations. If achieved, this milestone was more likely to be reached beyond the critical time window of 5-10 months.
SUMMARY
Canonical babbling appears promising as a potential marker for early detection of infants at risk for developmental disorders. In-depth studies on babbling characteristics in LDDDs are warranted.
综述目的
总结关于发育障碍发现较晚（LDDD）儿童，如自闭症谱系障碍、雷特综合征和脆性X综合征患儿典型咿呀学语的出现情况及特征。特别要探讨的是，婴儿出生后第一年的发声发展中是否包含有助于早期发现这些疾病的指标。
最新发现
仅有少数研究调查了LDDD婴儿的典型咿呀学语。由于采用了不同的研究范式和定义，关于典型咿呀学语的起始和特征的研究结果不一致，难以比较。LDDD婴儿发出典型咿呀学语声音的可能性降低。即便达到这一里程碑，也更有可能是在5至10个月的关键时间窗口之后实现的。
总结
典型咿呀学语有望成为早期发现发育障碍风险婴儿的潜在指标。有必要对LDDD患儿的咿呀学语特征进行深入研究。
