The present study examines the amount of input and output in congenitally hearing-impaired children with a cochlear implant (CI) and normally-hearing children (NH) and their normally-hearing mothers. The aim of the study was threefold: (a) to investigate the input provided by the two groups of mothers, (b) to investigate the output of the two groups of children, and (c) to investigate the influence of the mothers’ input on child output and expressive vocabulary size. Mothers are less influenced by their children’s hearing status than the children are: CI children are more talkative and slower speakers. Mothers influenced their children on most parameters, but strikingly, it was not maternal talkativeness as such, but the number of maternal turns that is the best predictor of a child’s expressive vocabulary size.

Phonological Processes are simplification of sounds which occur among the children during the younger age and will gradually diminish giving an adult like speech form. The aim of the present study is to analyze the occurrence of phonological processes among hearing impaired children who underwent cochlear implant surgery during their younger age as an early intervention. The subjects included in the study were 10 children (5 male and 5 female) who were diagnosed with congenital total hearing impairment and underwent cochlear implant surgery and attending Auditory verbal therapy. The task given to the subjects in the present study is to repeat the words in Tamil Articulation Test followed by the Clinician. The words were recorded and further analyzed for the occurrence of phonological processes. The results show that a total of 26 phonological processes (both typical and atypical) occurred with a maximum occurrence of Depalatalization and minimally of Final Consonant Deletion. The results of the present study help in providing a better knowledge about the occurrence of phonological processes which helps the speech language pathologist in intervening hearing impaired children with cochlear implants and to improve their speech intelligibility.

A review of the relevant literature indicates a lack of knowledge regarding suprasegmental speech characteristics in prelingual hearing impaired children with cochlear implants. This study is aimed at examining certain suprasegmental features in the speech of prelingual hearing impaired children with cochlear implants by perceptual ratings and acoustic analyses, comparing these results to that of prelingual hearing impaired children without implants, and normal hearing children of the same age. Twelve Afrikaans speaking children between the ages of six and ten years were included in three groups. An integrated view of the perceptual and acoustic results shows that the cochlear implanted children's suprasegmental speech characteristics bear closer resemblance to those of the normal hearing group than those of the hearing impaired group.

Abstract Studies on the speech and language development of hearing-impaired children often focus on (deviations in) the children’s speech production. However, it is unclear if listeners also perceive differences between the speech of normally hearing and hearing-impaired children. This contribution wants to fill this void by investigating the overall perceived speech quality of both groups. Three groups of listeners (speech and language pathologists, primary school teachers and inexperienced listeners) judged 126 utterances of seven normally hearing children, seven children with an acoustic hearing aid and seven children with a cochlear implant, in a comparative judgment task. All children were approximately seven years old and received, in the case of the hearing-impaired children, their assistive hearing device before the age of two. The online tool D-PAC was used to administer the comparative judgement task. The listeners compared stimuli in pairs and decided which stimulus sounded best. This method ultimately leads to a ranking in which all stimuli are represented according to their overall perceived speech quality. The main result is that the speech of normally hearing children was preferred by the listeners. This indicates that, even after several years of device use, the speech quality of hearing-impaired children is perceived as different from that of normally hearing children. Within the group of hearing-impaired children, cochlear implanted children were judged to exhibit higher speech quality than acoustically hearing aided children, especially after a longer device use. The speech quality of the latter group, on the other hand, remained practically stable. Listeners, irrespectively of their degree of experience with (hearing-impaired) children’s speech, completed the task similarly. In other words: the difference between the overall perceived speech quality of normally hearing and hearing-impaired children is salient for all listener groups and they all slightly preferred children with a cochlear implant over children with an acoustic hearing aid.

Exposure to modified speech has been shown to benefit children with languagelearning impairments with respect to their language skills (M. M. Merzenich et al., 1998; P. Tallal et al., 1996). In the study by Tallal and colleagues, the speech modification consisted of both slowing down and amplifying fast, transitional elements of speech. In this study, we examined whether the benefits of modified speech could be extended to provide intelligibility improvements for children with severe-to-profound hearing impairment who wear sensory aids. In addition, the separate effects on intelligibility of slowing down and amplifying speech were evaluated. Two groups of listeners were employed: 8 severe-to-profoundly hearingimpaired children and 5 children with normal hearing. Four speech-processing conditions were tested: (1) natural, unprocessed speech; (2) envelope-amplified speech; (3) slowed speech; and (4) both slowed and envelope-amplified speech. For each condition, three types of speech materials were used: words in sentences, isolated words, and syllable contrasts. To degrade the performance of the normal-hearing children, all testing was completed with a noise background. Results from the hearing-impaired children showed that all varieties of modified speech yielded either equivalent or poorer intelligibility than unprocessed speech. For words in sentences and isolated words, the slowing-down of speech had no effect on intelligibility scores whereas envelope amplification, both alone and combined with slowing-down, yielded significantly lower scores. Intelligibility results from normal-hearing children listening in noise were somewhat similar to those from hearing-impaired children. For isolated words, the slowing-down of speech had no effect on intelligibility whereas envelope amplification degraded intelligibility. For both subject groups, speech processing had no statistically significant effect on syllable discrimination. In summary, 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.

Spoken samples of language from a group of ten hearing impaired children were analysed with respect to development of occurrence of verb tenses and verb inflections, the development of the kernel sentence and four transformations: conjunction, particle displacement, auxiliary "have" and pronoun. The language samples represented an age range of five—three to nine—seven years. The mean hearing level of the ten subjects, in the better ear was 76dB I.S.O. From the results obtained, general conclusions seem to emerge. Firstly, the earliest acquired verb tense is the present, followed by, or appearing concurrently with, the present progressive. Secondly, the kernel sentence is correctly used at an early age by some children. As age increases, so does the percentage of children using the kernel sentence. From approximately seven years of age, more transformations are used. The transformations conjunction and particle displacement indicated a clear developmental trend towards greater complexity. The conjunction and pronoun transformations were used by a greater percentage of children. The transformation auxiliary "have" appeared much later and less frequently. These developmental trends show strong similarities to the trends observed in normal hearing children by other investigators. There is, however, a time lag in that the hearing impaired children develop these features at a later age and over a longer period of time.
