<b><i>Purpose:</i></b> Cochlear implant (CI) sound-processing strategies are important to the overall success of a CI recipient. This study aimed to determine the effects of 2 Advanced Bionics (AB) CI-processing strategies, Optima-S and Optima-P, on speech recognition outcomes in adult CI users. <b><i>Methods:</i></b> A retrospective chart review was completed at a tertiary academic medical center. Seventeen post-lingually deafened adult CI users (median age = 58.6 years; age range: 23.5–78.9 years) with long-term use of a paired sound-processing strategy (Optima-P) were reprogrammed with a sequential strategy (Optima-S). Demographic data and speech recognition scores with pre- and post-intervention analyses were collected and compared with respect to the 95% confidence interval for common CI word and sentence recognition tests. <b><i>Results:</i></b> Using Optima-S sound-processing strategy, all patients (100%) performed equivalent or better on word and sentence testing than with Optima-P. More specifically, 17.6, 41.2, and 58.8% of the patients performed above the 95% confidence interval for speech recognition conditions of monosyllabic words, sentences in quiet, and sentences in noise, respectively. All patients (100%) selected Optima-S as their preferred strategy for future CI use. <b><i>Conclusion:</i></b> Speech recognition performance with Optima-S processing strategy was stable or improved compared to results with Optima-P in all tested conditions, and subjective preference of Optima-S was selected by all patients. Given these results, CI clinicians should consider programming AB CI users with Optima-S sound-processing strategy to optimize overall speech recognition performance.

Objective The purpose of this systematic review is to evaluate the published research in auditory training (AT) for pediatric cochlear implant (CI) recipients. This review investigates whether AT in children with CIs leads to improvements in speech and language development, cognition, and/or quality of life and whether improvements, if any, remain over time post AT intervention. Method A systematic search of 7 databases identified 96 review articles published up until January 2017, 9 of which met the inclusion criteria. Data were extracted and independently assessed for risk of bias and quality of study against a PICOS (participants, intervention, control, outcomes, and study) framework. Results All studies reported improvements in trained AT tasks, including speech discrimination/identification and working memory. Retention of improvements over time was found whenever it was assessed. Transfer of learning was measured in 4 of 6 studies, which assessed generalization. Quality of life was not assessed. Overall, evidence for the included studies was deemed to be of low quality. Conclusion Benefits of AT were illustrated through the improvement in trained tasks, and this was observed in all reviewed studies. Transfer of improvement to other domains and also retention of benefits post AT were evident when assessed, although rarely done. However, higher quality evidence to further examine outcomes of AT in pediatric CI recipients is needed.

Mandarin Tones

In order to improve the pitch perception of cochlear implant (CI) users speaking tonal language, it has been suggested to frequency-modulate the electric stimulus rate by the spectral information of the tonal language. A piecewise CI rate modulation strategy has been recently proposed, which not only encoded the spectral information but also took account of the psychological perception feature for the stimulus rate variation by CI users. This paper further examines its performance to convey Mandarin tonal information by a neural-network-based simulation. The experimental results shown that the correct rates to identify the four Mandarin tones of 80 Mandarin monosyllabic words were 95%, 95%, 100% and 100%, respectively, indicating that the piecewise rate modulation strategy might efficiently convey Mandarin tonal information. Therefore, the piecewise rate modulation strategy could help to design novel CI electric stimulator and enhance the speech perception ability of CI users speaking tonal language, such as Mandarin.
