Auditory processing of speech is an important stage in the closed-loop human speech communication system. A computational auditory model for temporal processing of speech is described with details of numerical solution and of the temporal information extraction method given. The model is used to process fluent speech utterances and is applied to phonetic classification using both clean and nois...

 Abstract Background: The aim of this study was to determine the auditory performance of congenitally deaf children and the effect of cochlear implantation (CI) on speech intelligibility. Methods: Aprospective study was undertaken on 47 children in a pediatric tertiary referral center for CI. All children were deaf prelingually and were younger than 8 years of age. They were followed up until 5...

Of all the signals human auditory cortex has to process, the one with the most compelling relevance to the listener is arguably speech. Parsing and decoding speech—the conspecifi c signal affording the most rapid and most precise transmission of information—must be considered one of the principal challenges of the auditory system. This chapter concentrates on what speech perception entails and ...

Recent studies have yielded contradictory evidence on whether visual speech perception (watching articulatory gestures) can activate the human primary auditory cortex. To circumvent confounds due to inter-individual anatomical variation, we defined our subjects' Heschl's gyri and assessed blood oxygenation-dependent signal changes at 3 T within this confined region during visual speech percepti...

Recordings from single auditory neurons in response to speech and speech-like stimuli provide detailed descriptions of neural processing in the earliest stages of speech perception. These studies show that a great deal of information about both the formant pattern and voice pitch is available in both the average discharge rates and the temporal discharge patterns of auditory-nerve fibers and co...

The dichotomy between acoustic temporal envelope (ENV) and fine structure (TFS) cues has stimulated numerous studies over the past decade to understand the relative role of acoustic ENV and TFS in human speech perception. Such acoustic temporal speech cues produce distinct neural discharge patterns at the level of the auditory nerve, yet little is known about the central neural mechanisms under...

This selected overview of audiovisual (AV) speech perception examines the influence of visible articulatory information on what is heard. Thought to be a cross-cultural phenomenon that emerges early in typical language development, variables that influence AV speech perception include properties of the visual and the auditory signal, attentional demands, and individual differences. A brief revi...

Listeners vary in their ability to understand speech in noisy environments. Hearing sensitivity, as measured by pure-tone audiometry, can only partly explain these results, and cognition has emerged as another key concept. Although cognition relates to speech perception, the exact nature of the relationship remains to be fully understood. This study investigates how different aspects of cogniti...

Introduction  A cochlear implant in adolescent patients with pre-lingual deafness is still a debatable issue. Objective  The objective of this study is to analyze and compare the development of auditory speech perception in children with pre-lingual auditory impairment submitted to cochlear implant, in different age groups in the first year after implantation. Method  This is a retrospective st...
