This study is part of a series on speech-based first impressions of prelingually deaf cochlear implant (CI) users with differing speech intelligibility. Hiring managers with typical hearing (TH) rated CI users and TH young adults on various personality traits and suitability as job applicants after hearing recorded speech samples. Similar to prior…

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,…

Purpose: This study investigated whether listener processing of dysarthric speech requires the recruitment of more cognitive resources (i.e., higher levels of listening effort) than neurotypical speech. We also explored relationships between behavioral listening effort, perceived listening effort, and objective measures of word transcription…

Purpose: This study aimed to develop and test a measure of real-time continuous speech understanding to be used with natural dialogues. Method: The measure was based on a category monitoring paradigm and employed five existing recordings of natural dialogues from which the different test categories and associated target words were derived. For…

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…

Purpose: This study seeks to determine how speech-language impairments relate to the frequency and diversity of communication modes and functions produced by children with cerebral palsy (CP) during interactions with their mothers. Method: We studied 40 children with CP (M[subscript age] = 62 months) comprising three groups--those who were unable…

A case study examined the classroom behavior of a third grader named Andrea. Andrea's lips moved but no response could be heard. Because Andrea was an appealing child, her lack of oral communication became a challenge for her teacher. Members of the Educators Forum supported feelings that Andrea needed to be helped to use oral language. An…
