Little research has been conducted on the development of suprasegmental characteristics of vocalizations in typically developing infants (TDI) and the role of audition in the development of these characteristics. The purpose of the present study was to examine the longitudinal development of fundamental frequency (F(0)) in eight TDI and eight infants with severe-to-profound hearing loss matched for level of vocal development. Results revealed no significant changes in F(0) with advances in pre-language vocal development for TDI. Infants with hearing loss, however, showed a statistically reliable higher variability of F(0) than TDI, when age was accounted for as a covariate. The results suggest development of F(0) may be strongly influenced by audition.
关于典型发育婴儿（TDI）发声超音段特征的发展以及听觉在这些特征发展中的作用，所开展的研究较少。本研究的目的是考察8名TDI婴儿和8名重度至极重度听力损失婴儿的基频（F(0)）的纵向发展，这些婴儿在发声发展水平上相匹配。结果显示，对于TDI婴儿，随着前语言发声发展的推进，F(0)没有显著变化。然而，当将年龄作为协变量时，听力损失婴儿的F(0)变异性在统计学上比TDI婴儿更高。结果表明，F(0)的发展可能受到听觉的强烈影响。
