News: I will be presenting at ASA in San Diego on December 5th.
I am a Doctoral candidate in the Department of Linguistics at the University of Kansas, where I work with Allard Jongman in the KU Phonetics and Psycholinguistics Laboratory (KUPPL) on acoustic modeling and speech perception, and with Michael Vitevitch in the Department of Psychology on complex systems in speech. The broad aim of my work is to move away from the sound inventory perspective on the study of speech systems, toward an approach where acoustic and articulatory relations are fundamentally tied to the higher-order linguistic units they serve to distinguish in communication. My dissertation uses English as a test case for the development of this approach, but my interests span many other languages, particularly in India, where I did my Masters (at JNU in New Delhi and at EFLU in Hyderabad) and worked on several languages, including Assamese, Bodo, Garo, Kashmiri, Malayalam, Rabha, and Telugu.
Research InterestsComplexity in Speech Systems
- The study of speech as a complex system considers articulatory, acoustic, and perceptual structure to be an emergent function of communicative interactions between higher-order units (e.g., patterns in success/failure to transmit a given message).
- This approach requires that the speech system reflects the fundamental heterogeneity of distributions of contrast in higher-order units in the language, and therefore requires phonetic data to be much broader in scope (e.g., cross-linguistic comparisons would not be between controlled elicitations of phones, but between large databases of words or other higher-order units in each language).
- Recent work: Redmon & Jongman (2018, 2019). "Lexically dependent estimation of acoustic information in speech (I/II)"
- My work on speech production has focused primarily on obstruents, and in particular on the contextual asymmetries and points of instability that are a hallmark of such systems.
- Recent work: Redmon & Jongman (2018). "Source characteristics of voiceless dorsal fricatives"; Dutta et al. (2019, forthcoming). "Coarticulation in a dense coronal system: Acoustic and ultrasound data from Malayalam."
- The need for a broader linguistic base for research on human language production and perception is well-known and readily acknowledged.
- Two major gaps that remain are in the availability of computational resources and perceptual data for understudied languages. Regarding the latter it is of particular importance that such languages serve as grounds for both replicating existing psycholinguistic findings and generating new ones.
