Spectrotemporal Modulation Detection and Speech Perception by Cochlear Implant Users
Spectrotemporal modulation (STM) detection performance was examined for cochlear implant (CI) users. The test involved discriminating between an unmodulated steady noise and a modulated stimulus. The modulated stimulus presents frequency modulation patterns that change in frequency over time. In order to examine STM detection performance for different modulation conditions, two different tempor...
متن کاملThe perception of foreign-accented speech by cochlear implant users
The current study investigated the perception of foreign-accented speech by prelingually deaf, longterm cochlear implant (CI) users. CI and normalhearing (NH) listeners made judgements about the intelligibility of short sentences produced by native and non-native speakers of American English. While both CI and NH listeners rated foreign-accented sentences as less intelligible than native senten...
متن کاملPerception and Psychoacoustics of Speech in Cochlear Implant Users
Cochlear implants (CIs) are prosthetic devices that restore hearing in deaf individuals via electric stimulation of the auditory nerve through an electrode array inserted in the cochlea. The device consists of a microphone and an externally worn speech processor that converts acoustic signals into electric signals. The speech signal coded with electric pulses is then delivered via a wireless tr...
متن کاملCross-modal reorganization and speech perception in cochlear implant users.
Recent work suggests that once the auditory cortex of deaf persons has been reorganized by cross-modal plasticity, it can no longer respond to signals from a cochlear implant (CI) installed subsequently. To further examine this issue, we compared the evoked potentials involved in the processing of visual stimuli between CI users and hearing controls. The stimuli were concentric circles replaced...
متن کاملLong-term speech perception in elderly cochlear implant users.
IMPORTANCE A review of a test battery presented in both quiet and noise may clarify what the progression of speech perception abilities is in older adult cochlear implant users and whether the performance declines with advancing age. OBJECTIVE To examine whether older adults (≥65 years) with cochlear implants maintain stable speech perception performance after at least 10 years of listening e...
