Cortical Representations of Speech in a Multitalker Auditory Scene.
The ability to parse a complex auditory scene into perceptual objects is facilitated by a hierarchical auditory system. Successive stages in the hierarchy transform an auditory scene of multiple overlapping sources, from peripheral tonotopically based representations in the auditory nerve, into perceptually distinct auditory-object-based representations in the auditory cortex. Here, using magne...
متن کاملRegional accents affect speech intelligibility in a multitalker environment
The current understanding of listener sensitivity to regional accents comes from examination of speech processing in quiet and in noise. This study had two aims: 1) to examine the intelligibility of regional accents in a multitalker environment, and 2) to explore a methodological question of whether systematic regional features can be detected in the productions of only one representative talke...
متن کاملSpeech localization in a multitalker mixture.
An experiment was performed that measured, for the frontal audio-visual horizon, how accurately listeners could localize a female-voice target amidst four spatially distributed male-voice maskers. To examine whether listeners can make use of a priori knowledge about the configuration of the sources, performance was examined in two conditions: either the masker locations were fixed (in one of fi...
متن کاملChildren's perception of speech in multitalker babble.
Children 5, 9, and 11 years of age and young adults attempted to identify the final word of sentences recorded by a female speaker. The sentences were presented in two levels of multitalker babble, and participants responded by selecting one of four pictures. In a low-noise condition, the signal-to-noise ratio (SNR) was adjusted for each age group to yield 85% correct performance. In a high-noi...
متن کاملAttentional modulation of object representations in working memory.
We investigated the role of object-based attention in modulating the maintenance of faces and scenes held online in working memory (WM). Participants had to remember a face and a scene, while cues presented during the delay instructed them to orient their attention to one or the other item. Event-related functional magnetic resonance imaging revealed that orienting attention in WM modulated the...
