PROSODIC STRUCTURE

 Stress and Focus

Projects examining variability in production of various kinds of segments, related to stress and focus. Project supported by NSF Grant BCS-04406540 (“Prosody in Cross-Language Production and Perception” from August ,2005 – August, 2009.

 Syllabification

Project examining how a consonant’s affiliation shows up in speech production and perception.  This project began as a replication of Stetson’s old time experiments which showed a sensitivity to speech rate variation.  Project supported by NIDCD Grant R03 DC04095and NSF Grant BCS-9910701  (“Articulatory and Perceptual Correlates of Syllable Structure”), From September, 2000 – August, 2003. 

Quantity and Durational Dynamics

Projects related to the production and perception of lexically associated differences in duration, including work on Finnish, Japanese, Arabic, and English.

 Fundamental Frequency

Pieces from a variety of projects that deal with linguistic uses of pitch, including studies of tone, pitch accent and segmental microprosody. 

Korean Accent Systems

Project examining dialectal variation in Korean prosodic systems.  Varieties of Korean differ considerably in their use of pitch.  This project is primarily the work of Jungsun Kim, and examines perceptual, production, and acquisition aspects of this typological difference. 

 

SEGMENTAL STRUCTURE

Multiple dimensions in consonant production

A series of studies modelling the acoustic space of consonants, as done for the perceptual structure in the Perceptual Modelling project below. Project supported partially by NSF Grant BCS-04406540 (“Prosody in Cross-Language Production and Perception” from August, 2005 – August, 2009.

 Multiple dimensions in consonant perception

AKA: AMBEL.  Project developing methods to examine how different languages use the different acoustic dimensions which correlate with stop voicing contrasts. Project supported by NSF Grant BCS-04406540 (“Prosody in Cross-Language Production and Perception” from August ,2005 – August, 2009.

 Perceptual Modelling

A series of studies in modelling consonantal confusions, both by native English speakers and by non-native speakers. Project supported partially by NSF Grant BCS-04406540 (“Prosody in Cross-Language Production and Perception” from August ,2005 – August, 2009.

Rate Normalization

 Project examining how listeners manage to get perceptual identification of consonants, even in the face of the huge variation found in the Syllabification project. Project supported by NIDCD Grant R03 DC04095and NSF Grant BCS-9910701  (“Articulatory and Perceptual Correlates of Syllable Structure”), From September, 2000 – August, 2003.

 

SECOND LANGUAGE ACQUISITION

 Second Language Acquisition

A variety of related projects examining the abilities of learners of English to identify English anterior obstruents.  Project supported primarily by NSF Grant BCS-04406540 (“Prosody in Cross-Language Production and Perception” from August ,2005 – August, 2009, but also in its earlier stages by  NIDCD Grant R03 DC04095and NSF Grant BCS-9910701  (“Articulatory and Perceptual Correlates of Syllable Structure”), From September, 2000 – August, 2003.

 Bilingualism and Lexical Borrowing

Studies examining the relationship between the perceptual confusions found in the Second Language Acquisition Project and conventionalized patterns of lexical borrowing. Project supported partially by NSF Grant BCS-04406540 (“Prosody in Cross-Language Production and Perception” from August ,2005 – August, 2009.
