The Influence Of Socioindexical Information On The Speech Perception-Production Link: Evidence From A Shadowing Task, Kyler B. Laycock

Theses and Dissertations--Linguistics

The body of work on speech perception demonstrates the ability of listeners to utilize both visual and acoustic information in their processing of a given speech signal. More recent studies have established that listeners are sensitive to cues in both these modalities which inform their perception of a speaker's identity in parallel with the linguistic message, but the relationship between social information in perception and production together is unclear. This study reports the results of an experiment designed to test the hypothesis that expectations about a speakers identity is able to influence a listener's perception and production of speech in …

Cot In The Act: Ethnicity And Age Affects Phonemic Perception Of The Low-Back Merger In New York City English, Omar Ortiz

Dissertations, Theses, and Capstone Projects

ABSTRACT

This paper is an experimental study on how perceptions about a speaker’s age and ethnicity may influence whether listeners perceive the THOUGHT / LOT distinction. The macro-categories of age and ethnicity have been found to correlate with the lowering of raised THOUGHT (Wong 2012, Becker 2010) and the favoring of the merged vowels in perception (Haddican et al. 2016). This thesis examines whether images of faces associated with different age and ethnicity categories condition perception of auditory stimuli as belonging to either the LOT or THOUGHT class. This thesis builds on previous results suggesting that non-linguistic information influences speech …

Testing The Perceptual Magnet Effect In Monolinguals And Bilinguals, Michael C. Stern

Dissertations, Theses, and Capstone Projects

Previous research has demonstrated an apparent warping of the perceptual space whereby the best exemplars or ‘prototypes’ of speech sound categories minimize the perceptual distance between themselves and neighboring stimuli in the same category. This phenomenon has been termed the ‘perceptual magnet effect’ (PME). The present study extends work on the PME to a speech sound category previously unstudied in this paradigm (American English /æ/), and to bilingual speech sound representation and perception. American English monolinguals and Turkish-English bilinguals completed identification tasks, category goodness rating tasks, and same-different discrimination tasks with synthesized vowel sounds from the American English /æ/ category—not …

Preferential Early Attribution In Segmental Parsing, Amanda Rysling

Doctoral Dissertations

This dissertation investigates parsing in segmental perception, or the process by which listeners map the continuous acoustic signal that reaches their ears to the linguistic representations over which phonology operates. It addresses questions of when listeners decide that they have heard acoustic evidence about the identity of one speech sound, versus evidence about the identity of a following sound, and when this linguistic knowledge is applied relative to when it is received during the course of on-line perception and processing. The central argument advanced here is that the beginnings of answers to these questions require the recognition of a domain-general …
