Speaker: Rachel Walker
Title: Sub-segmental Representation
Time/Location:

  • Wednesday 2/22: 1-2:30pm in 36-112
  • Thursday 2/23: 4-5:30pm in 36-155

Description:

In this course, we will examine the representation of sub-segmental elements in light of patterns involving the neutralization of vowel quantity contrasts in the context of coda consonants. A case study of patterns of vocalic neutralization in General American English, supported by a real-time MRI study of speech articulation, will motivate a phonological representation of sub-segments as gestures (Browman & Goldstein 1986 et seq.). Key advantages that gestures offer are the representation of temporal coordination among sub-segments and encoding of goal articulatory states that may be blended under conditions of overlap. A phonological approach will be developed that governs sub-segmental temporal relations, formalized in terms of optimality theoretic constraints, building on proposals of Davidson (2003) and Smith (2016). Cross-linguistic predictions for patterns of vowel quantity neutralization in other languages and dialects will be considered.
