In this paper, we investigate the relative perceptual importance of the temporal envelop (TE) and temporal fine structure (TFS) between tonal language and non-tonal language perception. The “auditory chimera” experiment is conducted on both American English and Mandarin Chinese with the same conditions. Our experimental results show that there is no significant perceptual difference of TE and T...

The present paper provides a theoretical account of the auditory recognition process. The theory describes recognition in terms of the information in a preperceptual auditory image and the time it is available for perceptual processing. Auditory recognition processes are assumed to be analogous to those operating in visual recognition. Necessary distinctions are drawn between auditory detection...

Categorical perception (CP) is highly evident in audition when listeners' perception of speech sounds abruptly shifts identity despite equidistant changes in stimulus acoustics. While CP is an inherent property of speech perception, how (if) it is expressed in other auditory modalities (e.g., music) is less clear. Moreover, prior neuroimaging studies have been equivocal on whether attentional e...

Recent neuroimaging studies proposed the importance of the anterior auditory pathway for speech comprehension. Its clinical significance is implicated by semantic dementia or pure word deafness. Neurodegenerative or cerebrovascular nature, however, precluded precise localization of the cortex responsible for speech perception. Electrical cortical stimulation could delineate such localization by...

We investigated how the physical differences associated with the articulation of speech affect the temporal aspects of audiovisual speech perception. Video clips of consonants and vowels uttered by three different speakers were presented. The video clips were analyzed using an auditory-visual signal saliency model in order to compare signal saliency and behavioral data. Participants made tempor...

Recently, techniques motivated by human auditory perception are being applied in main-stream speech technology and there seems to be renewed interest in implementing more knowledge of human speech communication into a design of a speech recognizer. The paper discusses the author's experience with applying auditory knowledge to automatic recognition of speech. It advances the notion that the rea...

Speech perception requires the effortless mapping from smooth, seemingly continuous changes in sound features into discrete perceptual units, a conversion exemplified in the phenomenon of categorical perception. Explaining how/when the human brain performs this acoustic-phonetic transformation remains an elusive problem in current models and theories of speech perception. In previous attempts t...

BACKGROUND During speech perception, the ability to integrate auditory and visual information causes speech to sound louder and be more intelligible, and leads to quicker processing. This integration is important in early language development, and also continues to affect speech comprehension throughout the lifespan. Previous research shows that individuals with autism have difficulty integrati...

Some components of a speech signal, when made more intense, are heard simultaneously as speech and nonspeech--a form of duplex perception. At lower intensities, the speech alone is heard. Such intensity-dependent duplexity implies the existence of a phonetic mode of perception that takes precedence over auditory modes.

INTRODUCTION The objective of the evaluation of auditory perception of cochlear implant users is to determine how the acoustic signal is processed, leading to the recognition and understanding of sound. OBJECTIVE To investigate the differences in the process of auditory speech perception in individuals with postlingual hearing loss wearing a cochlear implant, using two different speech coding...
