Factors affecting speech recognition in noise and hearing loss in adults with a wide variety of auditory capabilities
Studies concerning speech recognition in noise constitute a very broad spectrum of work<br/>including aspects like the cocktail party effect or observing performance of individuals in<br/>different types of speech-signal or noise as well as benefit and improvement with hearing aids.<br/>Another …

Cognition and communication in children/adolescents with cochlear implant
A cochlear implant (CI) is a device that provides individuals with severe to profound hearing impairment (SPHI) with auditory stimulation, which makes it possible for them to develop skills related to spoken communication. We have little knowledge about how hearing with a CI influences cognitive …

Current steering and electrode spanning with partial tripolar stimulation mode in cochlear implants
<p>Cochlear implants (CIs) partially restore hearing sensation to profoundly deaf people by electrically stimulating the surviving auditory neurons. However, CI users perform poorly in challenging listening tasks such as speech recognition in noise and Cochlear implants (CIs) partially restore …

Neural and perceptual correlates of closed-loop sensorimotor training: basic and applied studies
The global hearing healthcare field is faced with two principal challenges. First, the demand for basic audiometric testing services far exceeds the capacity of trained clinicians even in high income countries, and this supply/demand mismatch is expected to worsen secondary to population aging. …

An analog VLSI vocal tract
Increasingly, circuit models of biology are being used to improve performance in engineering systems. For example, silicon-cochlea-like models have led to improved speech recognition in noise and low-power cochlear-implant processors for the deaf. A promising approach to improve the naturalness of …

An asynchronous,low-power architecture for interleaved neural stimulation, using envelope and phase information
… chip that together form a complete processing-and-stimulation cochlear-implant system. The processor chip uses a novel Asynchronous Interleaved Stimulation (AIS) algorithm that preserves phase and amplitude cues in its spectral input while simultaneously minimizing electrode interactions …

Perception of prosody by cochlear implant recipients
… implants (CIs) display remarkable success with speech recognition in quiet, but not with speech recognition in noise. Normal-hearing (NH) listeners, in contrast, perform relatively well with speech recognition in noise. Understanding which speech features support successful perception in noise …

Improving broadcast accessibility for hard of hearing individuals : using object-based audio personalisation and narrative importance
Technological advances in broadcasting can be the impetus for advances in accessibility services. For the 11 million individuals in the United Kingdom with some degree of hearing loss, the advent of object-based broadcasting and it’s personalisation features has the potential to facilitate a …

Speech perception in a sparse domain
… statistics are known to be important factors shaping our perceptual system. The visual and auditory systems have evolved to be efficient for processing natural images or speech. The common characteristics between natural images and speech are that they are both highly structured, therefore having …
