Speech is extremely variable along many different dimensions. One source of variability listeners often encounter is accented speech, in which phonological units can systematically differ from the listener's native categories. This dissertation presents five experiments testing how listeners adapt to accent-based phonological variability,…

The study explores the attitudes of undergraduate Flagship students in the United States towards Arabic-accented speech in English. It examines the Familiarity Principle among these students and analyzes their attitudes based on socio-intellectual status, aesthetic quality, and dynamism of Arabic-accented speech. The study also discusses the…

Speech-language pathologists (SLPs) make impressionistic intelligibility judgments as part of an evaluation of children for speech sound disorders. Despite the lack of formalization, it is an important measure of choice for SLPs, going beyond single-word standardized measures by using spontaneous speech to assess functional communication. However,…

The motor speech disorder of dysarthria is present in a substantial number of children with cerebral palsy (CP), leading to speech intelligibility deficits, which may negatively affect the children's communication and quality of life. Few studies to date have examined strategies for increasing intelligibility in children with dysarthria, and most…

Many studies evidence the flexibility of speech perception in the first language (L1), which allows rapid adaptation to unfamiliar foreign accents. Two influential studies by Bradlow and Bent (2008) and a follow-up study by Baese-Berk et al. (2013) found that increased variability as a function of the number of talkers and accents facilitated the…

Spoken words vary phonetically along a number of dimensions, such as duration, pitch, and vowel quality. Much of this variation is associated with social factors like the dialect, age, or gender of the speaker -- a type of variation termed 'socio-indexical'. Traditional theories of speech perception have seen this socio-indexical variation as a…

Linguistic stereotyping research posits that native speaker favor standard variety speakers which results in discrimination against non-native speakers (Rubin 2002, Kang & Rubin, 2009). However, it may be possible to improve native speaker attitudes towards accented speech, and through that, accented speakers. Research on improving native…

Over the past few decades, there has been considerable effort to find the mechanisms through which adult listeners can accommodate the rampant phonetic variation in natural speech. My dissertation concerns one source of variability: phonetic variation in speech produced by individuals with foreign accents. Mounting evidence shows that listeners…
