An Investigation Into Incorporating Visual Information in Audio Processing.

The number of persons with hearing and vision loss is on the rise as lifespans increase. Vision plays an important role in communication, especially in the presence of background noise or for persons with hearing loss. However, persons with vision loss cannot make use of this extra modality to overcome their hearing deficits. We propose automatically utilizing some visual information in hearing aids through the addition of a small wearable camera. Our initial results show potentially significant benefits to incorporating low level robust visual cues when the background noise is high. This technique can potentially benefit all persons with hearing loss, with substantial improvements possible for the speech perception performance of persons with dual sensory loss.
