Dr. Ko’s current research interests include the following topics:
1. Developmental changes and dynamics in mother-child speech: How, why, and when do mothers change their speech characteristics over the course of child language development?
2. Acoustic characteristics of child-directed speech: Do mothers’ speech characteristics systematically enhance certain aspects of speech directly relevant to language learning?
3. Prosodic bootstrapping in infant language processing: Infants use stress/accent cues and phrase-boundary cues for segmentation of speech stream. What are the relative contributions of these cues in infants’ speech segmentation?
4. Tempo-dependent mapping of phonological features on the acoustic level: How do speakers implement durational cues under varying speaking rates and how do listeners map them to the right phonological category? These questions are being investigated with focus on the vowel duration conditioned by consonantal voicing.
