Listening To Cursive: The Roles Of Regional Identity And Folk Beliefs In Perceptual Cue-Weighting, Stella Takvoryan

Theses and Dissertations--Linguistics

Listeners use knowledge acquired from experiences to weight phonetic-level cues to phonological contrasts. Phonetic knowledge is imbued with expectations about the contexts in which cues covary, speakers of a variety, and identity categories or constructs, so it can be challenging to distinguish expectations about variation from expectations about speakers. This study aims to explore the extent that expectations about iconic vowel quality variation in Southern American Englishes can drive cue-weighting. Listeners categorized stimuli with vowel qualities synthesized from an [ɛ]-[eɪ] continuum from a Southern and a non-Southern talker, with duration manipulated in tandem. Half of the participants saw a label …

A Perceptual Investigation Of Speech Rhythm Based On A Continuum Of Durational Change, Matthew Benton

Linguistics & TESOL Dissertations - Archive

Speech rhythm is a complicated prosodic feature of spoken languages. Being a suprasegmental feature, it is not a clear cut difference between tonal (Chinese) and non-tonal (English) languages. The popularization of defining languages in terms of their speech rhythms was popularized in the mid 1900’s. Terms like syllable-timed and stress-timed were coined and ever since then there has been much debate on what is a speech rhythm and why particular languages have different rhythms. While speech rhythm was initially a study based on how a listener perceived a spoken language, it became much more focused on measurements and attempts to …

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 …

L2 Perception Of Spanish Palatal Variants Across Different Tasks, Christine Shea, Jeffrey Renaud

Spanish: Faculty Scholarship & Creative Works

While considerable dialectal variation exists, almost all varieties of Spanish exhibit some sort of alternation in terms of the palatal obstruent segments. Typically, the palatal affricate [ɟʝ] tends to occur in word onset following a pause and in specific linear phonotactic environments. The palatal fricative [ʝ] tends to occur in syllable onset in other contexts. We show that listeners’ perceptual sensitivity to the palatal alternation depends upon the task and exposure to Spanish input. For native Spanish listeners, the palatal alternation boosts segmentation accuracy on an artificial speech segmentation task and also reduces latencies on a phonotactically-conditioned elision task. L2 …
