Psychophysical phenomena such as categorical perception and the perceptual magnet effect indicate that our auditory perceptual spaces are warped for some stimuli. This paper investigates the effects of two different kinds of training on auditory perceptual space.

2003-02-01 · These hypotheses extend Kuhl, 1992, Kuhl, 1994, Kuhl, 2000 Native Language Magnet Theory to further detail how perceptual warpings affect speech perception. It is telling that the most successful training procedures for teaching English /r/ and /l/ to Japanese adults have involved multi-talker high-variability stimulus sets (e.g. Logan, Lively, & Pisoni, 1991 ).

Perceptual magnet effect in speech perception

We here propose an unsupervised, adaptive neural network model which allows to control the relation between stimulus density and generalization capability, and which can account for the perceptual magnet effect. The perceptual magnet effect is one of the earliest known language-specific phenomena arising in infant speech development. The effect is characterized by a warping of perceptual space near phonemic category centers. Previous explanations have been formulated within the theoretical framework of cognitive psychology.

Apparently, the perceptual systems of CSEs may eventually adapt to accomodate new sounds at the cost of losing perceptual sensitivity to some of the native phonetic contrasts. 1. INTRODUCTION Infant speech perception has been explored extensively by Khul and cols. [5] who introduced a model known as the “perceptual magnet effect”.

The tests had to be performed in this order because the results of the identiﬁcation render the input stimuli for the goodness rating, and the results of the goodness rating render the input stimuli for the discrim-ination. Speech perception is the process by which the sounds of language are heard, interpreted, and understood. The study of speech perception is closely linked to the fields of phonology and phonetics in linguistics and cognitive psychology and perception in psychology.

This effect, if reliable, has important implications for how we categorize speech information. The perceptual magnet effect suggests that category centers are the basis for speech representation.

The perceptual magnet effect describes an increased generalization capability for the perception of vowels, if the perceived vowels are prototypical. We here propose an unsupervised, adaptive neural network model which allows to control the relation between stimulus density and generalization capability, and which can account for the perceptual magnet effect.

The ratio peak at Stimulus 8 for the 60-mel intervals is reliable (i.e., fixed and roving discriminations are significantly different) and indicates the existence of a perceptual anchor effect at that location. - "Perceptual magnet and phoneme boundary effects in speech perception: Do they arise from a common mechanism?"

The term perceptual magnet effect refers to the perceptual phenomenon of sensitivity minima near Equation 4 formalizes the idea of a perceptual magnet: the term µc pulls the perception of speech sounds toward the mean of the phonetic category, effectively shrinking percep-tual space around the phonetic category. The resulting per-ceptual pattern is shown in Figure 1 (a). Note that if there is no uncertainty about category membership, perception of speech sounds further from the category mean is more bi- The results demonstrated that sensitivity peaks at vowel boundaries were more influenced by stimulus range than were perceptual magnet effects; peaks in sensitivity near the /i/-/e/ boundary were reduced with restricted stimulus ranges and one-step intervals, but nüfüma in discrimination near the best exemplars of /i/ were present in all conditions.
