Forensic voice discrimination by lay listeners: The effect of speech type and background noise on performance

In forensic settings, lay (nonexpert) listeners may be required to compare voice samples for identity. In two experiments we investigated the effect of background noise and variations in speaking style on performance. In each trial, participants heard two recordings, responded whether the voices belonged to the same person, and provided a confidence rating. In Experiment 1, the first recording featured read speech and the second featured read or spontaneous speech. Both recordings were presented in quiet, or with background noise. Accuracy was highest when recordings featured the same speaking style. In Experiment 2, background noise either occurred in the first or second recording. Accuracy was higher when it occurred in the second. The overall results reveal that both speaking style and background noise can disrupt accuracy. Although there is a relationship between confidence and accuracy in all conditions, it is variable. The forensic implications of these findings are discussed.     

In Search of Śiva: Mahādēviyakka's V&īraśaivism

Mahādēviyakka was a radical 12th century Karnataka saint of whom surprisingly little has been written. Considered the most poetic of the Vīra?aivas, her vacanas are characterized by their desperate searching for ?iva. I attempt to convey Mahādēvi's epistemology and its struggle to 'know' ?iva, necessitating a lifetime of searching for him; offer an interpretation of the innate presence of ?iva in the world and its consequences for epistemology; and explore the sense of tragic love inherent in devotional searching for ?iva. My primary goal is to offer a powerful and positive, yet critical, interpretation of Mahādēvi's beautiful prose on her relationship with ?iva.     

On Changing the Subject

Sticking to the point is thought to be a good thing. Changing the subject, by contrast, is regarded as a sign of a wandering mind if it is unintentional and as a sign of duplicity if it is intentional. Yet, as I shall show, interpreters regularly replace an initial object of interpretation with a new object, thus "changing the subject." They do so in one of four ways: idealization, resegmentation, reconception, and recovery. Far from being symptomatic of either intellectual weakness or a desire to hide something, however, these processes are an intrinsic part of that most central of human intellectual endeavors, interpretation, and they contribute to its positive value.
