Open-set word and sentence speech-perception test scores are commonly used as a measure of hearing abilities in children and adults using cochlear implants and/or hearing aids. These tests are usually presented auditorily with a verbal response. In the case of children, scores are typically lower and more variable than for adults with hearing impairments using similar devices. It is difficult to interpret children’s speech-perception scores without considering the effects of lexical knowledge and speech-production abilities on their responses. This study postulated a simple mathematical model to describe the effects of hearing, lexical knowledge, and speech production on the perception test scores for monosyllabic words by children with impaired hearing. Thirty-three primary-school children with impaired hearing, fitted with hearing aids and/or cochlear implants, were evaluated using speech-perception, reading-aloud, speech-production, and language measures. These various measures were incorporated in the mathematical model, which revealed that performance in an open-set word-perception test in the auditory-alone mode is strongly dependent on residual hearing levels, lexical knowledge, and speech-production abilities. Further applications of the model provided an estimate of the effect of each component on the overall speech-perception score for each child.

PurposeWe sought to determine whether speech perception and language skills measured early after cochlear implantation in children who are deaf, and early postimplant growth in speech perception and language skills, predict long-term speech perception, language, and neurocognitive outcomes.MethodThirty-six long-term users of cochlear implants, implanted at an average age of 3.4 years, completed measures of speech perception, language, and executive functioning an average of 14.4 years postimplantation. Speech perception and language skills measured in the 1st and 2nd years postimplantation and open-set word recognition measured in the 3rd and 4th years postimplantation were obtained from a research database in order to assess predictive relations with long-term outcomes.ResultsSpeech perception and language skills at 6 and 18 months postimplantation were correlated with long-term outcomes for language, verbal working memory, and parent-reported executive functioning. Open-set word recognition was correlated with early speech perception and language skills and long-term speech perception and language outcomes. Hierarchical regressions showed that early speech perception and language skills at 6 months postimplantation and growth in these skills from 6 to 18 months both accounted for substantial variance in long-term outcomes for language and verbal working memory that was not explained by conventional demographic and hearing factors.ConclusionSpeech perception and language skills measured very early postimplantation, and early postimplant growth in speech perception and language, may be clinically relevant markers of long-term language and neurocognitive outcomes in users of cochlear implants.Supplemental materialshttps://doi.org/10.23641/asha.5216200

Communicative Context

By diminishing the role of communicative context, traditional tests of speech perception may underestimate or misrepresent the actual speech perception abilities of adults with a hearing impairment. This study investigates this contention by devising an assessment that may better simulate some aspects of "reallife" speech perception. A group of 31 participants with a severe-to-profound hearing impairment took part in a series of speech perception tests while wearing their hearing aids. The tests used question/answer or adjacency pairs, where the stimulus sentence was preceded by a question spoken by the participant. Four conditions were included: (a) where there was no initiating sentence, as in a traditional open-set speech perception test; (b) where the initiating question was neutral (e.g. "Why?"); (c) where there was a disruptive semantic relationship between the question and answer; and (d) where there was a strong contextual relationship between the question and answer. The time delay between the question and answer was also varied. Results demonstrated that in all conditions where there was a preceding question speech perception improved, and increasing the cohesion between the question and the reply improved speech perception scores. Additionally, time delay and the relatedness of the reply interacted. The effects of semantic context appeared to diminish over a 10-s period while other linguistic effects remained more constant. These results indicate the utility of simulating communicative environments within speech perception tests.

Optimal Adaptation

Changed hearing occurs when sensorineural loss is acquired or increases, when hearing aids or cochlear implants are first acquired, when hearing aids are reprogrammed, and when cochlear implants are remapped. The changes affect speech perception—a process in which decisions about a talker's language output are made on the basis of sensory and contextual evidence, using knowledge and skill. The importance of spoken communication dictates speedy and optimal adaptation to changed hearing. Adaptation is a process in which the individual acquires new knowledge and modifies skill. Formal training provides the listener with the opportunity to enhance both knowledge and skill by spending time on speech perception tasks without the demands, constraints, uncertainties, and risks associated with everyday communication. Benefits of such training have been demonstrated in terms of improvement on trained tasks and talkers, generalization to untrained tasks and talkers, improvements in self-perceived competence, and reduction of self-perceived handicap. So far, however, we lack information on which aspects of training are responsible for benefit, which aspects of perception are changed, how individual differences interact with the foregoing, and whether these benefits translate into significantly increased participation and quality of life.
