Association of Speech Processor Technology and Speech Recognition Outcomes in Adult Cochlear Implant Users

Objective: Determine association of advancements in speech processor technology with improvements in speech recognition outcomes. Study Design: Retrospective cohort. Setting: Tertiary referral center. Patients: Adult unilateral cochlear implant (CI) recipients. Intervention: Increasing novelty of speech processor defined by year of market availability. Main Outcome Measures: Consonant-Nucleus-Consonant (CNC) and Hearing in Noise Test (HINT) in quiet. Results: From 1991 to 2016, 1,111 CNC scores and 1,121 HINT scores were collected from 351 patients who had complete data. Mean post-implantation CNC score was 53.8% and increased with more recent era of implantation (p
