Loud bangs, bright flashes, and intense shocks capture attention, but other changes--even those of similar magnitude--can go unnoticed. Demonstrations of change blindness have shown that observers fail to detect substantial alterations to a scene when distracted by an irrelevant flash, or when the alterations happen gradually [1-5]. Here, we show that objects changing in hue, luminance, size, o...

INTRODUCTION Previous studies demonstrated that a decrement in the N1m response, a major deflection in the auditory evoked response, with sound repetition was mainly caused by bottom-up driven neural refractory periods following brain activation due to sound stimulations. However, it currently remains unknown whether this decrement occurs with a repetition of silences, which do not induce refra...

The effects of subunit formation on adult listeners' ability to notice changes in a continuous spectral gradient of sound were studied. Results of this experiment support the idea that the auditory system processes information differently within a unit, and that this processing does not occur unless the perceptual system detects unit boundaries. In this experiment, silences were inserted into a...

This paper presents an overview of speech recognition technology. This report presents an overview of speech recognition technology, software, development and applications. It begins with a description of how such systems work, and the level of accuracy that can be expected. Present work is aimed at developing suitable speech recognition for hindi language, for the people who are physically ham...
