This paper describes the Buckeye corpus of spontaneous American English speech, a 307,000-word corpus containing the speech of 40 talkers from central Ohio, USA. The method used to elicit and record the speech is described, followed by a description of the protocol that was developed to phonemically label what talkers said. The results of a test of labeling(More)
obtained this compensation for coarticulation effect when the word-final fricatives were replaced with an ambiguous phoneme and argued that this indicated top-down lexical involvement in a prelexical process, as predicted by interactive models of speech perception. But autonomous models, which have no top-down processing but which are sensitive to the(More)
The question of how one should decide among competing explanations of data is at the heart of the scientific enterprise. Computational models of cognition are increasingly being advanced as explanations of behavior. The success of this line of inquiry depends on the development of robust methods to guide the evaluation and selection of these models. This(More)
To model behavior, scientists need to know how models behave. This means learning what other behaviors a model can produce besides the one generated by participants in an experiment. This is a difficult problem because of the complexity of psychological models (e.g., their many parameters) and because the behavioral precision of models (e.g., interval-scale(More)
Three experiments examined attentional allocation during speech processing to determine whether listeners capitalize on the rhythmic nature of speech and attend more closely to stressed than to unstressed syllables. Ss performed a phoneme monitoring task in which the target phoneme occurred on a syllable that was either predicted to be stressed or(More)
Recent studies that used Ganong's (1980) identification task have produced discrepant results. The present study sought to resolve these discrepancies by examining the influence of methodological factors on phoneme identification and differences in data analysis techniques. Three factors were examined across 2 experiments: position of target phoneme,(More)
In 2 experiments the author investigated how musicians and nonmusicians differentially perceive the dimensions of pitch and timbre. A categorization task was used in Experiment 1 to assess Ss' ability to identify how 2 consecutively presented tones changed along these dimensions. A speeded classification task was used in Experiment 2 to measure Ss' ability(More)
The lexical identification shift is used as a measure of speech processing in the phoneme identification task (W. F. Ganong, 1980). Interactive (bottom-up and top-down) models of word recognition account for the shift by claiming that lexical knowledge feeds back to a prelexical level and aids speech processing. Autonomous models (bottom-up only) maintain(More)
The perception of consonant clusters that are phonotactically illegal word initially in English (e.g., /tl/,/sr/) was investigated to determine whether listeners' phonological knowledge of the language influences speech processing. Experiment 1 examined whether the phonotactic context effect (Massaro & Cohen, 1983), a bias toward hearing illegal sequences(More)
One account of how pronunciation variants of spoken words (center-> "senner" or "sennah") are recognized is that sublexical processes use information about variation in the same phonological environments to recover the intended segments (Gaskell & Marslen-Wilson, 1998). The present study tests the limits of this phonological inference account by examining(More)
