Pattern Playback in the 90s

چکیده
Deciding the appropriate representation to use for modeling human auditory processing is a critical issue in auditory science. While engineers have successfully performed many single-speaker tasks with LPC and spectrogram methods, more difficult problems will need a richer representation. This paper describes a powerful auditory representation known as the correlogram and shows how this non-linear representation can be converted back into sound, with no loss of perceptually important information. The correlogram is interesting because it is a neurophysiologically plausible representation of sound. This paper shows improved methods for spectrogram inversion (conventional pattern playback), inversion of a cochlear model, and inversion of the correlogram representation.

The Arts in Psychotherapy Playback theatre and recovery in mental health: Preliminary evidence
Playback theatre is a community-building improvisational theatre in which a personal story told by a group member is transformed into a theatre piece on the spot by other group members. Playback theatre combines artistic expression and social connection based on story-telling and empathic listening, thus bringing together modes thought to promote healing. Here, we explore the potential of playb...
متن کاملPattern playback revisited: unvoiced stop consonant perception.
Among the most influential publications in speech perception is Liberman, Delattre, and Cooper's [Am. J. Phys. 65, 497-516 (1952)] report on the identification of synthetic, voiceless stops generated by the Pattern Playback. Their map of stop consonant identification shows a highly complex relationship between acoustics and perception. This complex mapping poses a challenge to many classes of r...

Aim: Family representation in the media expresses dominant discourses about its structure and patterns, and the media can create, confirm, or modify these discourses. This article looks at how family rules, structures, and patterns have evolved over the past few decades, and how cinema has played a role in this transformation and discourse, and in what ways, tools, as well as the changes in the...
متن کاملMob Mentality: Effect of a Mobbing Playback on Avian Detection Probabilities during Point Count Surveys
The probability of detecting an individual or species is an important parameter in studies using mark-recapture and occupancy models to estimate population sizes and occurrence. Because low detection probabilities result in biased estimators and decreased precision, biologists seek methods that maximize detection probability. We evaluated whether we could increase detections of bird species by ...
متن کاملFemale eavesdropping on male song contests in songbirds.
Male song reflects the quality of the singer in many animals and plays a role in female choice of social and copulation partners. Eavesdropping on male-male vocal interactions is a means by which females can compare different males’ singing behavior directly and make immediate comparisons between potential partners on the basis of their relative vocal performance (1, 2). Using an interactive pl...
