Individuals with aphasia have more problems detecting small differences between speech sounds than larger ones. This paper reports how phonemic processing is impaired and how this is influenced by speechreading. A non-word discrimination task was carried out with ‘audiovisual’, ‘auditory only’ and ‘visual only’ stimulus display. Subjects had to decide whether two presented stimuli were the same. Six aphasic subjects with speech sound processing difficulties and 14 non-brain-damaged control… 
Processing of audiovisual stimuli in aphasic and non-brain-damaged listeners
Background: During speech perception not only auditory but also visual information (seen speech) is processed. This was shown by, for example, McGurk and MacDonald (1976). In their study participants
Audiological Assessment of Word Recognition Skills in Persons With Aphasia.
Clinicians should not be reticent to use this test if patients are able to repeat single words, but routine use of alternative tests is encouraged for populations of people with brain injuries.
Hearing loss and auditory processing ability in people with aphasia
The results suggest that the prevalence of hearing loss for people with aphasia (at least for this group) is no greater than the general population, however, they are significantly more affected in their recognition of speech in noise and experience greater disability in listening situations than people without aphasIA.
Therapy for auditory processing impairment in aphasia: An evaluation of two approaches
Aims: This study evaluated two forms of discrimination therapy for auditory processing impairment in aphasia. It aimed to determine whether therapy can improve speech perception and/or help
Rehabilitation in aphasia: Using brain and behavioural measures to investigate the effects of a digital speech comprehension therapy
This thesis investigates the development and testing of a novel tablet-based speech comprehension therapy, for persons with chronic aphasia (PWA). // In Chapter 1 of this thesis, I present a
Severe, Chronic Auditory Comprehension Deficits: An Intensive Treatment and Cueing Protocol
Individuals with severe, chronic comprehension impairments can increase single word comprehension and benefit from repetition cues when provided intensive treatment.

Deficits in Auditory, Cognitive, and Motor Processing Following Reversible MCAO in Mice: Understanding the Human Stroke Phenotype
Stoke is characterized by a loss or alteration in neurological and/or bodily function resulting from a cerebral vascular accident (interruption of blood flow to the brain), which may include various forms of aphasia (language loss), cognitive deficits, cognitive deficits (including attentional and memory impairments), and motor impairments.
Audiovisual processing in aphasic and non-brain-damaged listeners
Het onderzoek wees verder uit dat visuele ondersteuning (liplezen), die een positieve invloed heeft op de spraakverwerking, zich niet beperkt tot hele duidelijke herkenbare klankkenmerken, zoals de plaats van uitspraak.


Selective acoustic phonetic impairment and lexical access in an aphasic patient.
The relationship between acoustic-phonetic disturbances and lexical access was explored in an aphasic patient and the results are consistent with a role for a phonemic code in auditory word recognition, coupled with lexical-to-acoustic/phonetics feedback, but are also compatible with the view that other access codes for the Phonological Input Lexicon are also available.
Remediating a speech perception deficit in an aphasic patient
Abstract This paper describes the assessment and treatment of an aphasic patient, J.S., who had multiple language deficits. In particular, pre-speech and speech-level perceptual processes were both

Dissociations in auditory word comprehension; evidence from nine fluent aphasic patients
Abstract Traditional aphasia classifications do not allow for a detailed description of auditory comprehension impairments. A cognitive neuropsychological model of lexical processing allows us to

Identification versus Discrimination of Distinctive Features in Speech Perception
Dichotically presented CV syllables were presented to 24 normal subjects under two contrasting performance requirements: consonant identification and consonant discrimination and it was proposed that the results of the identification task reflect the degree of information load in short-term memory.
Hearing lips and seeing voices
The study reported here demonstrates a previously unrecognised influence of vision upon speech perception, on being shown a film of a young woman's talking head in which repeated utterances of the syllable [ba] had been dubbed on to lip movements for [ga].
