We investigate speech perception and production using a variety of approaches
- acoustic phonetics
- articulatory phonetics
- laboratory phonology
- Phonetic variation (production, perception)
- Vowel perception (models, mechanisms)
- Coarticulation, acoustic nasality
- Human-voice AI interaction
- Perception of apparent speaker characteristics
- Speaker production adaptations (clear speech, child-DS)
- Social factors in phonetic imitation
- Mechanisms of sound change
