An infant's vocal capacity develops significantly during the first year of life. Research suggests early measures of pre-speech development, such as canonical babbling and volubility, can differentiate typical versus disordered development. This study offers a new contribution by comparing early vocal development in 10 infants with Fragile X syndrome and 14 with typical development. Results suggest infants with Fragile X syndrome produce fewer syllables and have significantly lower canonical babbling ratios compared to infants who are typically developing. Furthermore, the particular measures of babbling were strong predictors of group membership, adding evidence regarding the possible utility of these markers in early identification.
婴儿的发声能力在生命的第一年有显著发展。研究表明，早期的前语言发展指标，如典型咿呀学语和话语流利度，能够区分正常发育与发育障碍。本研究通过比较10名患有脆性X综合征的婴儿和14名发育正常婴儿的早期发声发展，提供了新的贡献。结果表明，与发育正常的婴儿相比，患有脆性X综合征的婴儿发出的音节更少，典型咿呀学语的比例也显著更低。此外，咿呀学语的具体指标是分组的有力预测指标，为这些指标在早期识别中的可能效用增添了证据。
