Vocal emotion recognition performance predicts the quality of life in adult cochlear implant users.

Clinical tests of cochlear implant (CI) outcomes in sentence recognition cannot fully reflect CI users' self-reported quality of life (QoL). Here, vocal emotion recognition scores, speech reception thresholds (SRTs), and demographic factors were tested as predictors of QoL scores assessed with the Nijmegen Cochlear Implant Questionnaire in postlingually deafened adult CI users. After correction for multiple comparisons, vocal emotion recognition scores were significantly correlated with QoL scores in all subdomains (social interaction, self-esteem, etc.), while SRTs and duration of CI use were not. Vocal emotion recognition may thus be used in clinic to accurately and broadly predict QoL with CIs.
