The mean sentence recognition score for Mandarin Speech Perception was 78.8%. For the Cantonese Hearing In Noise Test, the mean sentence recognition score was 61.3%. The mean sentence recognition score for the Mandarin Hearing in Noise Test was 68.5%. In the 10 studies that reported preoperative data, the mean pure-tone average and speech recognition scores significantly improved post-cochlear implantation. <br /><br />In one study of emotional recognition, Mandarin-speaking adults with CIs recognized emotions in spectrally degraded vocoded speech with similar accuracy as listeners with typical hearing. One study evaluated quality of life; all subdomain scores improved significantly following cochlear implantation.
