Infants’ and Adults’ Use of Temporal Cues in Consonant Discrimination
Material type: TextSubject(s): Online resources: In: Ear & Hearing July-August 2017 (VOL. 38, NO. 4, 497–506)Abstract: Adults can use slow temporal envelope cues, or amplitude modulation (AM), to identify speech sounds in quiet. Faster AM cues and the temporal fine structure, or frequency modulation (FM), play a more important role in noise. This study assessed whether fast and slow temporal modulation cues play a similar role in infants’ speech perception by comparing the ability of normal-hearing 3-month-olds and adults to use slow temporal envelope cues in discriminating consonants contrasts.
