Telephone speech comprehension with use of the nucleus cochlear implant.

The reported telephone usage by cochlear implant recipients has become a major issue of controversy. Although patients and clinicians report good communication skills via the telephone, no standardized tests have been used and no quantifiable results have been reported. In an effort to determine the extent to which our better-performing patients can use the telephone, we established a clinical protocol to assess their ability to recognize speech, taking into consideration the problems inherent in telephone testing. Eight cochlear implant recipients were administered the NU-6 Monosyllabic Word Test and the City University of New York Topic Related Sentences under the following listening conditions: soundfield in a soundproof suite and via telephone within the hospital, locally, and long-distance. Twenty-three percent of the patients implanted at New York University Medical Center demonstrated a significant degree of telephone communication ability.

Ability of nucleus cochlear implantees to recognize music.

Eight adults with cochlear implants participated in experiments to test their ability to recognize music. Some subjects showed good ability to recognize songs that were sung with instrumental accompaniment but poor ability to recognize songs played on an electronic keyboard without verbal cues, indicating that they were recognizing the songs by verbal cues rather than by musical qualities such as tones and melodic intervals. This conclusion was strengthened by the finding that subjects were barely able to distinguish between songs with the same rhythm and pitch range, and they showed poor ability to discriminate musical intervals. (The closest discrimination was 4 semitones.) Subjects had good ability to distinguish among the synthesized sounds of various musical instruments played on the electronic keyboard. We speculate that subjects could distinguish the various musical instruments in the same way they distinguish among human voices using spectrographic patterns such as formants or maxima.
