In this paper, the details of processing algorithms used in a training program with language learning-impaired children (LLI's) are described. The training program utilized computer games, speech/language training exercises, books-on-tape and educational CD-ROM's. Speech tracks in these materials were processed using these algorithms. During a four week training period, recognition of both processed and normal speech in these children continually increased to near age-appropriate levels. We… 
Effectiveness of computerised spelling training in children with language impairments: a comparison of modified and unmodified speech input
This study evaluated a computerised program for training spelling in 8- to 13-yearolds with receptive language impairments. The training program involved children typing words corresponding to
Intelligibility of modified speech for young listeners with normal and impaired hearing.
Without extensive exposure to the speech processing conditions, children with impaired hearing and children with normal hearing listening in noise received no intelligibility advantage from either slowed speech or envelope-amplified speech.

452 children in classrooms at 9 U.S. elementary school districts were identified by their teachers as being “at-risk” for failure in reading and language arts. Standardized testing revealed that
Effect of intensive training on auditory processing and reading skills
Computer-mediated tools for the investigation and rehabilitation of auditory and phonological processing in aphasia
Background : Advances in technology have enhanced our ability to use computers to manipulate the spectrotemporal characteristics of speech waveforms in ways that can influence the processing of
Resistance of grammatical impairment to computerized comprehension training in children with specific and non-specific language impairments.
Rote training of comprehension of reversible sentences does not seem to be an effective approach to remediating such problems, and the pattern of performance suggested that the problem was not a lack of syntactic knowledge, but rather limited processing capacity that led to failures of on-line computation of meaning.
Case Studies of Auditory Training for Children With Auditory Processing Difficulties: A Preliminary Analysis
© NSSLHA 93 1092-5171/05/3202-0093 ABSTRACT: Seven children between the ages of 7 and 9 years with auditory processing difficulties participated for 20 days in intensive treatments designed to
Computer-supported phonological awareness intervention for kindergarten children with specific language impairment.
The results suggest that kindergarten children with SLI benefit from computer intervention for phonological awareness skills.
The effects of Fast ForWord Language on the phonemic awareness and reading skills of school-age children with language impairments and poor reading skills.
The improvement in phonemic awareness, but not reading, in the FFW-L, CALI, and ILI interventions limits their use with children who have language impairment and poor reading skills, similar results across treatment conditions suggest that acoustically modified speech was not a necessary component for improving phonemicawareness.


Language Comprehension in Language-Learning Impaired Children Improved with Acoustically Modified Speech
A speech processing algorithm was developed to create more salient versions of the rapidly changing elements in the acoustic waveform of speech that have been shown to be deficiently processed by
Temporal Processing Deficits of Language-Learning Impaired Children Ameliorated by Training
Children with language-based learning impairments with major deficits in their recognition of some rapidly successive phonetic elements and nonspeech sound stimuli were engaged in adaptive training exercises mounted as computer "games" designed to drive improvements in their "temporal processing" skills.
Deficits in auditory temporal and spectral resolution in language-impaired children
The data support the view that language difficulties result from problems in auditory perception, and provide further information about the nature of these perceptual problems that should contribute to improving the diagnosis and treatment of language impairment and related disorders.

Speech processed with programs implementing the contrast alteration procedure was presented to listeners with moderate to severe sensorineural hearing loss, and tokens with enhanced contrast showed moderate gains in percentage correct stop consonant identification when compared to unaltered tokens.
Training new, nonnative speech contrasts: a comparison of the prototype and perceptual fading techniques.
These results show that training with appropriately selected prototype stimuli can produce a linguistically meaningful improvement in a listener's ability to identify new, nonnative speech sounds--both natural and synthetic.
Defects of Non-Verbal Auditory Perception in Children with Developmental Aphasia
Examining children with developmental aphasia demonstrated inferior discrimination of sound quality to which a sequencing difficulty could be secondary and suggested that auditory perceptual deficits, particularly of sequencing, may be the primary dysfunction.
Central auditory system plasticity: generalization to novel stimuli following listening training.
The results demonstrate that training can generalize to listening situations beyond those used in training sessions, and that the preattentive central neurophysiology underlying perceptual learning are altered through auditory training.
Central Auditory System Plasticity Associated with Speech Discrimination Training
The results demonstrate that listening training can change the neurophysiologic responses of the central auditory system to just-perceptible differences in speech.
