The Nature of Prosodic Systems in Natural Human Communication
How do stress, intonation, and syllabic parsing effects get conventionalized in languages, and how do they function? Stress: how does it differ across languages, and how does it interact with segmental contrast in production and perception? Syllabification: how does syllabification affect segmental production and perception, and how does it interact with production pressures? This project has been supported by grants from the National Science Foundation and National Institutes of Health.
Second Language Production and Perception
There is a lot to learn about how to predict what effects will arise with second language hearers and perceivers. What we do know, shows that learners are very different from one another, and such variation seems very useful for understanding the relationship between speaking, listening, and the linguistic system.
The Relationship between Speaking and Listening and Variation across Individuals
How segments get perceived isn't always the same as how they get produced. Also, different individuals exhibit differences in how they encode acoustic effects in their production systems. Finally, differences in these individuals is known and accounted for by listeners. This variation has got to be important in determining how a linguistic system works, but I'm not sure how, and am sure curious about it.
Phonetic Facts as Historical Pressures
We know that various aspects of speaking and listening get recoded in the structure of a linguistic system, but how? Many likely mechanisms require lots of time, implicating historical linguistics as an important discipline for would-be phoneticians and phonologists. But how does the historical process work, and how much is involved in individual speakers and listeners here and now?
