Twenty children who have worn a Cochlear Corporation cochlear implant for an average of 33.6 months participated in a device-on/off experiment. They spoke 14 monosyllabic words three times each after having not worn their cochlear implant speech processors for several hours. They then spoke the same speech sample again with their cochlear implants turned on. The utterances were phonetically transcribed by speech-language pathologists. On average, no difference between speaking conditions on indices of vowel height, vowel place, initial consonant place, initial consonant voicing, or final consonant voicing was found. Comparisons based on a narrow transcription of the speech samples revealed no difference between the two speaking conditions. Children who were more intelligible were no more likely to show a degradation in their speech production in the device-off condition than children who were less intelligible. In the device-on condition, children sometimes nasalized their vowels and inappropriately aspirated their consonants. Their tendency to nasalize vowels and aspirate initial consonants might reflect an attempt to increase proprioceptive feedback, which would provide them with a greater awareness of their speaking behavior.

Purpose Children with dyslexia have speech production deficits in a variety of spoken language contexts. In this article, we discuss the nature of speech production errors in children with dyslexia, including those who have a history of speech sound disorder and those who do not, to familiarize speech-language pathologists with speech production–specific risk factors that may help predict or identify dyslexia in young children. Method In this tutorial, we discuss the role of a phonological deficit in children with dyslexia and how this may manifest as speech production errors, sometimes in conjunction with a speech sound disorder but sometimes not. We also briefly review other factors outside the realm of phonology that may alert the speech-language pathologist to possible dyslexia. Results Speech-language pathologists possess unique knowledge that directly contributes to the identification and remediation of children with dyslexia. We present several clinical recommendations related to speech production deficits in children with dyslexia. We also review what is known about how and when children with speech sound disorder are most at risk for dyslexia. Conclusion Speech-language pathologists have a unique opportunity to assist in the identification of young children who are at risk for dyslexia.

Background Standards for auditory rehabilitation are currently lacking for adults who receive cochlear implants. Speech recognition outcomes are highly variable, and many adults with cochlear implants present with suboptimal performance. Functional real-life communication abilities are not routinely measured clinically and are not strongly linked to performance on traditional measures of speech recognition. In fact, even individuals with relatively good speech recognition outcomes often present with persistent communication difficulties. In contrast to pediatric cochlear implant users, speech-language pathologists are not routinely involved in the rehabilitation of adults who receive cochlear implants. Purpose The purpose of this article is to describe the value of including a speech-language pathologist in a comprehensive approach to auditory rehabilitation for adults with cochlear implants. Method The theoretical and clinical foundations of incorporating a speech-language pathologist into an adult auditory rehabilitation program are discussed. A description of the skills and potential roles of the speech-language pathologist for providing adult cochlear implant rehabilitation services is presented, along with potential barriers to implementation. Conclusion Person-centered management of postlingually deafened adults with cochlear implants can be augmented by a more complete approach utilizing the skill set of a speech-language pathologist.

Intelligible Speech

The four purposes of this investigation were to assess whether children acquire intelligible speech following prolonged cochlear-implant experience and examine their speech error patterns, to examine how age at implantation influences speech acquisition, to assess how speech production and speech perception skills relate, and to determine whether cochlear implant recipients who formerly used simultaneous communication (speech and manually coded English) begin to use speech without sign to communicate. Twenty-eight prelinguistically deafened children who use a Nucleus cochlear implant were assigned to one of three age groups, according to age at implantation: 2–5 yrs (N = 12), 5–8 yrs (N = 9), and 8–15 yrs (N = 7). All subjects had worn a cochlear implant for at least 24 mos, and an average of 36 mos. All subjects used simultaneous communication at the time of implantation. Subjects performed both imitative and structured spontaneous sampling speech tasks. The results permit the following conclusions: (a) children who have used a cochlear implant for at least 2 yrs acquire some intelligible speech; (b) children who receive a cochlear implant before the age of 5 yrs appear to show greater benefit in their speech production skills than children who are older, at least after a minimum of 2 yrs of use; (c) children who recognize more speech while wearing their cochlear implants are likely to speak more intelligibly; and, (d) signing does not disappear from a child’s communication mode following implantation.

Over Time

The House 3M cochlear implant system is currently undergoing clinical trials in profoundly deaf children aged 2 through 18 years. Although the use of the implant in children continues to be controversial, the evidence to date indicates that this prosthesis can provide significant benefit for a selected population of profoundly deaf children. As of August 1985, a total of 189 children have received the cochlear implant. The majority of these children were deafened by bacterial meningitis. The children as a group show significant improvement of hearing performance and speech production abilities over time. Children implanted at a younger age (under 5 years) show an even more significant improvement in speech skills. Significantly improved speech production occurs in both the oral/aural children (most cases postlingually deaf) and the total communication children (most cases prelingually deaf). Psychological tests have shown improved performance on intelligence measures, perceptual motor tests, and academic achievement ratings. Surgical and postoperative complications have been minimal, with few measurable adverse effects.

Therapy Program

Purpose In this study, the authors examined the treatment efficacy of a behavioral speech therapy protocol for adult cochlear implant recipients. Method The authors used a multiple-baseline, across-behaviors and -participants design to examine the effectiveness of a therapy program based on behavioral principles and methods to improve the production of target speech sounds in 3 adults with cochlear implants. The authors included probe items in a baseline protocol to assess generalization of target speech sounds to untrained exemplars. Pretest and posttest scores from the Arizona Articulation Proficiency Scale, Third Revision (Arizona–3; Fudala, 2000) and measurement of speech errors during spontaneous speech were compared, providing additional measures of target behavior generalization. Results The results of this study provided preliminary evidence supporting the overall effectiveness and efficiency of a behavioral speech therapy program in increasing percent correct speech sound production in adult cochlear implant recipients. The generalization of newly trained speech skills to untrained words and to spontaneous speech was demonstrated. Conclusion These preliminary findings support the application of behavioral speech therapy techniques for training speech sound production in adults with cochlear implants. Implications for future research and the development of aural rehabilitation programs for adult cochlear implant recipients are discussed.

The University

A group of 10 children, adolescents, and prelinguistically deafened adults were implanted with the 22-electrode cochlear implant (Cochlear Pty Ltd) at the University of Melbourne Cochlear Implant Clinic and have used the prosthesis for periods from 12 to 65 months. Postoperative performance on the majority of closed-set speech perception tests was significantly greater than chance, and significantly better than preoperative performance for all of the patients. Five of the children have achieved substantial scores on open-set speech tests using hearing without lipreading. Phoneme scores in monosyllabic words ranged from 30% to 72%; word scores in sentences ranged from 26% to 74%. Four of these 5 children were implanted during preadolescence (aged 5:5 to 10:2 years) and the fifth, who had a progressive loss, was implanted during adolescence (aged 14:8 years). The duration of profound deafness before implantation varied from 2 to 8 years. Improvements were also noted over postoperative data collection times for the younger children. The remaining 5 patients who did not demonstrate open-set recognition were implanted after a longer duration of profound deafness (aged 13:11 to 20:1 years). The results are discussed with reference to variables that may affect implant performance, such as age at onset of loss, duration of profound loss, age at implantation, and duration of implantation. They are compared with results for similar groups of children using hearing aids and cochlear implants.

Vocoded Speech

Purpose An increasing number of individuals with residual or even normal contralateral hearing are being considered for cochlear implantation. It remains unknown whether the presence of contralateral hearing is beneficial or detrimental to their perceptual learning of cochlear implant (CI)–processed speech. The aim of this experiment was to provide a first insight into this question using acoustic simulations of CI processing. Method Sixty normal-hearing listeners took part in an auditory perceptual learning experiment. Each subject was randomly assigned to one of three groups of 20 referred to as NORMAL, LOWPASS, and NOTHING. The experiment consisted of two test phases separated by a training phase. In the test phases, all subjects were tested on recognition of monosyllabic words passed through a six-channel “PSHC” vocoder presented to a single ear. In the training phase, which consisted of listening to a 25-min audio book, all subjects were also presented with the same vocoded speech in one ear but the signal they received in their other ear differed across groups. The NORMAL group was presented with the unprocessed speech signal, the LOWPASS group with a low-pass filtered version of the speech signal, and the NOTHING group with no sound at all. Results The improvement in speech scores following training was significantly smaller for the NORMAL than for the LOWPASS and NOTHING groups. Conclusions This study suggests that the presentation of normal speech in the contralateral ear reduces or slows down perceptual learning of vocoded speech but that an unintelligible low-pass filtered contralateral signal does not have this effect. Potential implications for the rehabilitation of CI patients with partial or full contralateral hearing are discussed.

Abstract Background YouTube is increasingly used as a source of healthcare information. This study evaluated the quality of videos on YouTube about cochlear implants. Methods YouTube was searched using the phrase ‘cochlear implant’. The first 60 results were screened by two independent reviewers. A modified Discern tool was used to evaluate the quality of each video. Results Forty-seven videos were analysed. The mean overall Discern score was 2.0 out of 5.0. Videos scored higher for describing positive elements such as the benefits of a cochlear implant (mean score of 3.4) and scored lower for negative elements such as the risks of cochlear implant surgery (mean score of 1.3). Conclusion The quality of information regarding cochlear implant surgery on YouTube is highly variable. These results demonstrated a bias towards the positive attributes of cochlear implants, with little mention of the risks or uncertainty involved. Although videos may be useful as supplementary information, critical elements required to make an informed decision are lacking. This is of particular importance when patients are considering surgery.
