To investigate cry melody properties in infants with clefts using objective methods and to identify early differences in cry development in relation to infants without clefts that may indicate special developmental risks.
Melody analysis was carried out on cries from the second month of life. The cry properties of infants with a cleft lip and palate (CLP) and infants with a cleft palate only (CP) were quantitatively compared. Both groups were compared to infants without clefts.
Twenty-one infants with nonsyndromic clefts, including 11 infants with CLP and 10 infants with CP, were compared to 50 healthy controls.
Frequency spectrograms and melody diagrams of about 7000 cries were analyzed. For each infant's crying, melodic and rhythmic properties were investigated and expressed by appropriate quantitative indices. Based on previous studies, the degree of melody complexity in an infants' crying was used as an indicator of their present prespeech developmental status.
The cleft groups did not significantly differ from each other with respect to their cry melody development. However, both groups were significantly different from the control group, exhibiting a lower proportion of complex cry melodies and a deviation in rhythmicity. No significant correlation to hearing performances was found that could explain the differences.
Infants with clefts differ in their cry development from infants without clefts at 2 months of life. This early difference occurs before the infants undergo any surgical intervention or other treatment.
采用客观方法研究腭裂婴儿的哭声旋律特性，并确定与非腭裂婴儿相比哭声发育的早期差异，这些差异可能表明存在特殊的发育风险。
对出生后第二个月的哭声进行旋律分析。对唇腭裂（CLP）婴儿和单纯腭裂（CP）婴儿的哭声特性进行定量比较。将这两组婴儿与非腭裂婴儿进行比较。
21名非综合征性腭裂婴儿，包括11名CLP婴儿和10名CP婴儿，与50名健康对照婴儿进行比较。
分析约7000次哭声的频率谱图和旋律图。对每个婴儿的哭声，研究其旋律和节奏特性并用适当的定量指标表示。根据先前的研究，婴儿哭声的旋律复杂程度用作其当前言语前发育状况的指标。
腭裂组在哭声旋律发育方面彼此无显著差异。然而，两组与对照组均有显著差异，表现为复杂哭声旋律的比例较低且节奏存在偏差。未发现与听力表现有显著相关性可以解释这些差异。
腭裂婴儿在出生2个月时哭声发育与非腭裂婴儿不同。这种早期差异发生在婴儿接受任何手术干预或其他治疗之前。
