RESUMEN
This study tests the effects of intonational contours and filtering conditions on listener judgments of ethnicity to arrive at a more comprehensive understanding on how prosody influences these judgments, with implications for austomatic speech recognition systems as well as speech synthesis. In a perceptual experiment, 40 American English listeners heard phrase-long clips which were controlled for pitch accent type and focus marking. Each clip contained either two H* (high) or two L+H* (low high) pitch accents and a L-L% (falling) boundary tone, and had also previously been labelled for broad or narrow focus. Listeners rated clips in two tasks, one with unmodified stimuli and one with stimuli lowpass filtered at 400 Hz, and were asked to judge whether the speaker was "Black" or "White". In the filtered condition, tokens with the L+H* pitch accent were more likely to be rated as "Black", with an interaction such that broad focus enhanced this pattern, supporting earlier findings that listeners may perceive African American Language as having more variation in possible pitch accent meanings. In the unfiltered condition, tokens with the L+H* pitch accent were less likely to be rated as Black, with no effect of focus, likely due to the fact that listeners relied more heavily on available segmental information in this condition. These results enhance our understanding of cues listeners rely on in making social judgments about speakers, especially in ethnic identification and linguistic profiling, by highlighting perceptual differences due to listening environment as well as predicted meaning of specific intonational contours. They also contribute to our understanding of the role of how human listeners interpret meaning within a holistic context, which has implications for the construction of computational systems designed to replicate the properties of natural language. In particular, they have important applicability to speech synthesis and speech recognition programs, which are often limited in their capacities due to the fact that they do not make such holistic sociolinguistic considerations of the meanings of input or output speech.
RESUMEN
What is the relationship between ethnolinguistic communities and ways of speaking? Who is an authentic speaker of an ethnolinguistic variety? In a time where scholarly and public conceptualizations of race and ethnicity are variable and rapidly changing, potential effects on both self-identification and ways of speaking present an area ripe for study. However, linguistics and allied fields have often overlooked individuals and communities that do not neatly conform to well-defined racial categories. As multiracially identified individuals are one of the fastest growing demographic groups in the United States, researchers will necessarily need to address the way that traditional methodologies have excluded individuals and groups who fall outside of these racial and ethnic categories. This presents a unique challenge for sociolinguistics in particular, since we are interested in how people draw on linguistic variation to perform aspects of their identities, including their races and ethnicities. This study examines the ways in which race and ethnicity have been traditionally conceptualized in linguistics and allied fields, and draws on research from other social sciences to see how they have begun to study individuals who fall outside of traditionally pre-existing social categories. The study also briefly discusses the results of one of the first major sociolinguistic studies on multiracially identified participants, which found substantial effects of self-conceptualization and self-identification on linguistic behavior of these participants. Finally, it will address future questions and directions for research at the intersection of personal identity, race, and language.
