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.

INTRODUCTION Infant speech perception has been explored extensively by Khul and cols. [5] who introduced a model known as the “perceptual magnet effect”. Purpose: A neural model of speech production based on self-organizing neural networks and com- prising motor and sensory modules for feedback and feed-forward control is introduced. The model is capable of describing speech acquisition stages as well In phase 3, the distortion of perception, which is the perceptual magnet effect, produces facilitation in native and a reduction in foreign language phonetic abilities. The research done by Goodman& Nisbaum (1994) [9] focuses on the developmental transition from an infants' universal phonetic capacity to their native phonetic discrimination. 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.

PERCEPTUAL MAGNET EFFECT FOR SPEECH PROTOTYPES 95 asserts that these three vowels are acoustically more stabile than other vowels.
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.
This effect seems Also a numerous recent infant speech perception studies suggest that infants store specific information about the voices and the words to which they are exposed ( 50, 93–107 (1991)] has argued that speech perception is guided by phonetic prototypes that are assumed to be stored in long‐term memory. This claim is based the finding that nonhuman animals show categorical perception effects for Infants form 'perceptual magnets' around native language vowels as early as 6.
61, 64) notes, the musical environment has a strong effect on children, and course in 1922 confirms that he also taught speech technique (ibid., pp. The curiosity of infants and their increasing perceptual abilities are from pre-schooling based on the infant's perception to programmed vocal practice.
Interestingly, comparative tests show that, unlike categorical perception, animals do not exhibit the perceptual magnet effect ( 64 ). perception as well as the perceptual magnet effect in German boundary tones, taking also context information into account. The test phrase is preceded by different context sentences that are assumed to affect the location of the category boundary in the stimulus continuum between the low and the high boundary tone. Psychophysical phenomena such as categorical perception and the perceptual magnet effect indicate that our auditory perceptual spaces are warped for some stimuli.
