Perception of regional and nonnative accents
Online testing for behavioral research has become an increasingly used tool. Although more researchers have been using online data collection methods, few studies have assessed the replicability of findings for speech intelligibility tasks. Here we assess intelligibility in quiet and two noise-added conditions for several different accents of English (Midland American, Standard Southern British, Scottish, German-accented, Mandarin-accented, Japan…
The Targetedness of English Schwa
Schwa in English shows a considerable amount of contextual variation, to the extent that previous work has proposed that it is acoustically targetless. Although the consensus of previous research seems to suggest that schwa is targeted, the sources of schwa's contextual variation have yet to be fully explained. We explored a potential source of variation in English schwa, namely, whether schwa occurs in a content word (word-initial schwa, e.g., a…
Relative Contributions of Social, Contextual, and Lexical Factors in Speech Processing
This exploratory study examined the simultaneous interactions and relative contributions of bottom-up social information (regional dialect, speaking style), top-down contextual information (semantic predictability), and the internal dynamics of the lexicon (neighborhood density, lexical frequency) to lexical access and word recognition. Cross-modal matching and intelligibility in noise tasks were conducted with a community sample of adults at a l…
Second dialect acquisition and phonetic vowel reduction in the American Midwest
Effects of dialect-specific features and familiarity on cross-dialect phonetic convergence
The Development of Sociolinguistic Competence across the Lifespan
This study investigated the developmental trajectories of three perceptual domains related to regional dialect competence: the linguistic domain, tested through an intelligibility in noise task; the objective indexical domain, tested through locality judgments and a free classification task; and the subjective indexical domain, tested through smart and friendly judgments. To allow direct comparison across domains, participants aged 4–71 years (N …
Regional dialect perception across the lifespan
Although adult listeners can often identify a talker’s region of origin based on his or her speech, young children typically fail in dialect perception tasks, and little is known about the development of regional dialect representations from childhood into adulthood. This study explored listeners’ understanding of the indexical importance of American English regional dialects across the lifespan. Listeners between 4 and 79 years old in the Midwes…
Assessing predictability effects in connected read speech
A wide range of reduction phenomena have been described in the literature as predictability effects, in which more predictable units (i.e. words, syllables, vowels) are reduced in duration or other acoustic dimensions relative to less predictable units. The goal of the current study was to critically evaluate these predictability effects on vowel duration in read speech to explore the extent to which they reflect a single underlying phenomenon. T…
Effects of Lexical Competition and Dialect Exposure on Phonological Priming
A cross-modal lexical decision task was used to explore the effects of lexical competition and dialect exposure on phonological form priming. Relative to unrelated auditory primes, matching real word primes facilitated lexical decision for visual real word targets, whereas competing minimal pair primes inhibited lexical decision. These effects were robust across two English vowel pairs (mid–front and low–front) and for two listener groups (mono-d…

Children's perception of dialect variation
A speaker's regional dialect is a rich source of information about that person. Two studies examined five- to six-year-old children's perception of regional dialect: Can they perceive differences among dialects? Have they made meaningful social connections to specific dialects? Experiment 1 asked children to categorize speakers into groups based on their accent; Experiment 2 asked them to match speakers to (un)familiar cultural items. Each child …
Effects of dialect on vowel acoustics and intelligibility
A great deal of recent research has focused on phonetic variation among American English vowels from different dialects. This body of research continues to grow as vowels continuously undergo diachronic formant changes that become characteristic of certain dialects. Two experiments using the Nationwide Speech Project corpus (Clopper & Pisoni 2006a) explored whether the Midland dialect is more closely related acoustically and perceptually to the M…
The Prosody of Focus in Paraguayan Guaraní
In many languages, prosodic prominence indicates which expressions of an utterance are focused. This study explores the prosody of focus in Paraguayan Guaraní (Tupí-Guaraní) through two production and two perception experiments conducted with native speakers of Guaraní in Paraguay. The results of the production experiments suggest that prosodic prominence is realized by stressed syllable duration, f0 slope, and pitch accent type. While the percep…
Effects of gender and regional dialect on prosodic patterns in American English
Computational Methods for Normalizing Acoustic Vowel Data for Talker Differences
Direct acoustic-phonetic comparison of vowels produced by different talkers can be difficult due to the effects of anatomical and physiological talker differences on first and second formant frequencies. Since the mid-1960s, numerous computational algorithms have been proposed to normalize formant frequency measures and reduce the effects of talker-specific variability. These algorithms vary widely in their conceptualization: some require samples…
Free classification of American English dialects by native and non-native listeners
Perception of Dialect Variation in Noise
Listeners can explicitly categorize unfamiliar talkers by regional dialect with above-chance performance under ideal listening conditions. However, the extent to which this important source of variation affects speech processing is largely unknown. In a series of four experiments, we examined the effects of dialect variation on speech intelligibility in noise and the effects of noise on perceptual dialect classification. Results revealed that, on…

Some acoustic cues for the perceptual categorization of American English regional dialects
Homebodies and army brats
Early linguistic experience has been shown to affect speech perception in a variety of ways. The present experiment investigated the effects of early linguistic experience on dialect perception. Two groups of participants listened to sentences read by talkers from six American English dialects and were asked to identify where they thought the talkers were from using a forced-choice categorization task. We found that "army brats," who had lived in…
Effects of region of origin and geographic mobility on perceptual dialect categorization
Recent findings have shown that listeners' region of origin and geographic mobility affect their perception of dialect-specific properties of speech in vowel identification and dialect categorization tasks. The present study examined the perceptual dialect classification performance of four groups of listeners using a six-alternative forced-choice categorization task. The residential history of the listeners was manipulated so that the four group…

Effects of Talker Gender on Dialect Categorization
The identification of the gender of an unfamiliar talker is an easy and automatic process for naïve adult listeners. Sociolinguistic research has consistently revealed gender differences in the production of linguistic variables. Research on the perception of dialect variation, however, has been limited almost exclusively to male talkers. In the present study, naïve participants were asked to categorize unfamiliar talkers by dialect using sentenc…

Prosodic Effects on Word Reduction
It is widely known that English-speaking children reduce words by omitting syllables in certain predictable patterns (e.g., banána ~n ána). One way to better understand the nature of phonological reductions in children is to examine adults'word reduction behavior. This study explored whether adults produce predictable output patterns when reducing words. Undergraduate participants heard a list of polysyllabic words varying systematically across s…

Some acoustic cues for the perceptual categorization of American English regional dialects
Acoustic characteristics of the vowel systems of six regional varieties of American English
Previous research by speech scientists on the acoustic characteristics of American English vowel systems has typically focused on a single regional variety, despite decades of sociolinguistic research demonstrating the extent of regional phonological variation in the United States. In the present study, acoustic measures of duration and first and second formant frequencies were obtained from five repetitions of 11 different vowels produced by 48 …
