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 Despite the recommendation for cochlear implant (CI) processor use during all waking hours, variability in average daily wear time remains high. Previous work has shown that objective wear time is significantly correlated with speech recognition outcomes. We aimed to investigate the causal link between daily wear time and speech recognition outcomes and assess one potential underlying mechanism, spectral processing, driving the causal link. We hypothesized that increased CI use would result in improved speech recognition via improved spectral processing. Method Twenty adult CI recipients completed two study visits. The baseline visit included auditory perception testing (speech recognition and spectral processing measures), questionnaire administration, and documentation of data logging from the CI software. Participants watched an educational video, and they were informed of the compensation schedule. Participants were then asked to increase their daily CI use over a 4-week period during everyday life. Baseline measures were reassessed following the 4-week period. Results Seventeen out of 20 participants increased their daily CI use. On average, participants’ speech recognition improved by 3.0, 2.4, and 7.0 percentage points per hour of increased average daily CI use for consonant–nucleus–consonant words, AzBio sentences, and AzBio sentences in noise, respectively. Questionnaire scores were similar between visits. Spectral processing showed significant improvement and accounted for a small amount of variance in the change in speech recognition values. Conclusions Improved consistency of processor use over a 4-week period yielded significant improvements in speech recognition scores. Though a significant factor, spectral processing is likely not the only mechanism driving improvement in speech recognition; further research is warranted.

Auditory Recognition

Resumo: A reabilitação auditiva por meio do implante coclear tem constituído um campo de atuação e de pesquisa interdisciplinar, cujos interesses têm incidido na investigação das variáveis e processos relacionados às habilidades de linguagem dessa população. O presente estudo teve como objetivo apresentar uma revisão sistemática das pesquisas que investigaram as relações entre o uso do implante coclear e o desenvolvimento da linguagem. Para isso, foi realizada uma busca nas bases científicas Web of Science(r), Scielo(r) e LILACS(r), de 2003 a 2013, de estudos sob escopo da Audiologia (e de áreas correlatas), Educação, Reabilitação e Ciências do Comportamento; aplicando os unitermos "cochlear implant", "auditory recognition", "recognition", "speech", "speech production" e "language". Após um tratamento inicial dos resultados, foram selecionados para análise 86 artigos que foram classificados de acordo com os seguintes critérios: ano de publicação, periódico, área de pesquisa, tipo de estudo, habilidade investigada e a temática. Os resultados indicaram crescente avanço nesses estudos e uma ênfase em avaliar e/ou identificar possíveis fatores que interferem nos processos de linguagem de implantados cocleares, sendo essas pesquisas conduzidas majoritariamente pela Audiologia e áreas correlatas. Os estudos comparativos e explicativos foram os mais frequentes e têm destacado as habilidades auditivas, especificamente os fatores que afetam a percepção auditiva. Enquanto perspectivas futuras, poderão ser vislumbrados maior envolvimento científico de áreas interdisciplinares à Audiologia, ampliação de pesquisas sobre habilidades expressivas (como a produção oral) e fomento à estudos que investiguem intervenções (práticas baseadas em evidências) em linguagem para esse público.
