Abstract: The research in speech analysis is recognized to be an important aspect in the area of speech processing, with applications in speech coding, speech recognition, etc. Depending on the application, the speech ...

Abstract : Closed set speaker identification experiments were performed on a SPIDRE subset of the switchboard corpus with matched and mismatched telephone handset conditions. The impact of mismatched and matched conditions ...

Abstract : Many studies explored mechanisms through which the brain encodes sensory inputs allowing a coherent behavior. The brain could identify stimuli via a hierarchical stream of activity leading to a cardinal neuron ...

Abstract : Visual and auditory prostheses involve surgeries that are complex, expensive, and invasive. They are limited to a small number of electrodes and can only be used when the impairment is peripheral. The Vibe and ...

Abstract : Visual neurons coordinate their responses in relation to the stimulus; however, the complex interplay between a stimulus and the functional dynamics of an assembly still eludes neuroscientists. To this aim, ...

L’accent est placé dans cet article sur la structure hiérarchique, l’aspect parcimonieux de la représentation de l’information sonore, la très grande dimension des caractéristiques ainsi que sur l’indépendance des ...

Abstract : We present an example of an anthropomorphic approach, in which auditory-based cues are combined with temporal correlation to implement a source separation system. The auditory features are based on spectral ...

Abstract : Orientation-selective neurons shift their preferred orientation after being adapted to a nonpreferred orientation. These shifts of the peaks of tuning curves may be in the attractive or repulsive direction in ...

Abstract : Neural correlations (noise correlations and cross-correlograms) are widely studied to infer functional connectivity between neurons. High noise correlations (Rsc) between neurons have been reported to increase ...

Abstract : Cortical microcircuitry plays a pivotal role in encoding sensory information reaching the cortex. However, the fundamental knowledge concerning the mechanisms that govern feature-encoding by these sub-networks ...
