“…More specifically, CI users showed better-defined phonemic categories in perception tasks one year after implantation than one month, and like typical hearing (TH) individuals, are much better at differentiating sounds that span across phonemic boundaries than sounds within a single phoneme category (Lane et al, 2007b). As a consequence of these perceptual improvements, their speech tends to become more intelligible after receiving CIs (Vick et al, 2001;Abbs et al, 2020;Cychosz et al, 2021;Gautam et al, 2019;Priner et al, 2021;Svirsky et al, 1992Svirsky et al, , 1998Ubrig et al, 2010). CI users show improved contrasts in their voiced versus voiceless consonants after getting their CIs (Lane and Perkell, 2005), and demonstrate increased phoneme contrast in their speech when their CIs are turned on as opposed to turned off (Bharadwaj et al, 2006(Bharadwaj et al, , 2007Matthies et al, 1996;Richardson et al, 1993;Lane et al, 2007a).…”

Humans rely on auditory feedback to monitor and adjust their speech for clarity. Cochlear implants (CIs) have helped over a million people restore access to auditory feedback. Access to these feedback signals significantly improves speech production, but there is substantial variability in outcomes. This study aims to investigate the extent to which CI users can use their auditory feedback to detect self-produced sensory errors and make adjustments to their speech, given the coarse spectral resolution provided by their implants. First, we used an auditory discrimination task to assess the sensitivity of CI users to small differences in the formant frequencies of their own self-produced vowels. Then, CI users produced words under conditions of altered auditory feedback in order to assess sensorimotor adaptation to auditory error. Almost half of the CI participants tested can detect small, within-channel differences in their self-produced vowels, and they can also utilize this auditory feedback towards speech adaption. A typical hearing control group showed better sensitivity to the shifts in vowels, even in vocoded speech (CI-simulated speech), and elicited more robust speech adaptation behavior than the CI participants. Nevertheless, this study confirms that CI users can compensate for sensory errors in their speech, and supports the idea that sensitivity to these errors is related to variability in production.
