Speech perception studies typically rely on trained research assistants to score orthographic listener transcripts for words correctly identified. While the accuracy of the human scoring protocol has been validated with strong intra- and inter-rater reliability, the process of hand-scoring the transcripts is time-consuming and resource intensive. Here, an open-source computer-based tool for automated scoring of listener transcripts is built (Autoscore) and validated on three different human-scored data sets. Results show that not only is Autoscore highly accurate, achieving approximately 99% accuracy, but extremely efficient. Thus, Autoscore affords a practical research tool, with clinical application, for scoring listener intelligibility of speech.

In the visual domain, Marsolek and colleagues (1999, 2008) have found support for two dissociable and parallel neural subsystems underlying object and shape recognition: an abstract-category subsystem that operates more effectively in the left cerebral hemisphere (LH), and a specific-exemplar subsystem that operates more effectively in the right cerebral hemisphere (RH). Evidence of this asymmetry has been observed in priming specificity for linguistic (words, pseudoword forms) and nonlinguistic (objects) stimuli. In the auditory domain, the authors previously found hemispheric asymmetries in priming effects for linguistic (spoken words) and nonlinguistic (environmental sounds) stimuli. In the present study, the same asymmetrical pattern …

Evidence of this asymmetry has been observed for linguistic (words, pseudo-word forms) and non-linguistic (objects) stimuli. In the auditory domain, the authors previously found hemispheric asymmetries in priming effects when linguistic stimuli (spoken words) were used. In the present study, hemispheric asymmetries were investigated for non-linguistic stimuli (environmental sounds) by …
Challenges Facing A Complementary-Systems Approach To Abstract And Episodic Speech Perception, Conor T. Mclennan
Challenges Facing A Complementary-Systems Approach To Abstract And Episodic Speech Perception, Conor T. Mclennan

It has been nearly a decade since the publication of Goldinger’s [4] Psych. Review paper in which he presented his episodic theory of lexical access. Moreover, Goldinger’s (and others’) empirical work [3, 14] providing evidence for episodic representations predates the formal presentation of his episodic theory. This is an appropriate time to note how the field has progressed in the past decade with respect to the debate over the nature of lexical representations. As evidenced by the two main papers, the emphasis is no longer on whether there are abstract and/or episodic representations. Instead, the focus is now on the …

Variability in talker identity, one type of indexical variation, has demonstrable effects on the speed and accuracy of spoken word recognition. Furthermore, neuropsychological evidence suggests that indexical and linguistic information may be represented and processed differently in the 2 cerebral hemispheres, and is consistent with findings from the visual domain. For example, in visual word recognition, changes in font affect processing differently depending on which hemisphere initially processes the input. The present study examined whether hemispheric differences exist in spoken language as well. In 4 long-term repetition-priming experiments, the authors examined responses to stimuli that were primed by stimuli that …
The Time Course Of Variability Effects In The Perception Of Spoken Language: Changes Across The Lifespan, Conor T. Mclennan
The Time Course Of Variability Effects In The Perception Of Spoken Language: Changes Across The Lifespan, Conor T. Mclennan
Psychology Faculty Publications
Although spoken language is communicated via a rapidly varying signal, human listeners recognize spoken words both quickly and accurately. Nonetheless, variability in speech does have implications for both the processes and representations involved in spoken language perception. Moreover, variability effects have been observed across the lifespan, ranging from infants to older adults. Many factors could potentially modulate the degree to which variability affects spoken language perception. In particular, recent findings demonstrate that variability effects follow a time course, manifesting themselves at predictable points during perceptual processing. However, time course investigations are currently limited to young adults. Therefore, the current paper …
Representation Of Lexical Form: Evidence From Studies Of Sublexical Ambiguity, Conor T. Mclennan, Paul A. Luce, Jan Charles Luce

The authors examined the role of intermediate, sublexical representations in spoken word perception. In particular, they tested whether flaps, which are neutralized allophones of intervocalic /t/s and /d/s, map onto their underlying phonemic counterparts. In 2 shadowing tasks, the authors found that flaps primed their carefully articulated counterparts, and vice versa. Because none of the flapped stimuli were lexically ambiguous (e.g., between rater and raider), these results provide evidence that such priming is sublexically mediated. Therefore, the current study provides further insights into when underlying form-based representations are activated during spoken word processing. In particular, the authors argue that phonological …

Variability in talker identity and speaking rate, commonly referred to as indexical variation, has demonstrable effects on the speed and accuracy of spoken word recognition. The present study examines the time course of indexical specificity effects to evaluate the hypothesis that such effects occur relatively late in the perceptual processing of spoken words. In 3 long-term repetition priming experiments, the authors examined reaction times to targets that were primed by stimuli that matched or mismatched on the indexical variable of interest (either talker identity or speaking rate). Each experiment was designed to manipulate the speed with which participants processed the …

The authors attempted to determine whether surface representations of spoken words are mapped onto underlying, abstract representations. In particular, they tested the hypothesis that flaps—neutralized allophones of intervocalic /t/s and /d/s—are mapped onto their underlying phonemic counterparts. In 6 repetition priming experiments, participants responded to stimuli in 2 blocks of trials. Stimuli in the 1st block served as primes and those in the 2nd as targets. Primes and targets consisted of English words containing intervocalic /t/s and /d/s that, when produced casually, were flapped. In all 6 experiments, reaction times to target items were measured as a function of prime …
