Discrimination of Voice Pitch and Vocal-Tract Length in Cochlear Implant Users
OBJECTIVES When listening to two competing speakers, normal-hearing (NH) listeners can take advantage of voice differences between the speakers. Users of cochlear implants (CIs) have difficulty in perceiving speech on speech. Previous literature has indicated sensitivity to voice pitch (related to fundamental frequency, F0) to be poor among implant users, while sensitivity to vocal-tract length...
متن کاملDiscrimination of emotional and linguistic prosody with cochlear implant simulations
In cochlear implants (CI), temporal sound features are more successfully transmitted than spectral sound features. This could have consequences for the perception of prosody. This was tested for emotion vs. focus perception in simulated CI hearing, starting from the assumption that for emotional prosody spectral (F0) features are more important than for focus prosody. Sets of short Dutch phrase...
متن کاملVoice discrimination in cochlear implant users
Abstract Due to the limited processing of spectral cues, voice discrimination might be restricted in cochlear implant (CI) users. A very basic representation of different voices is given by the speaker gender. Important characteristics are the fundamental frequency (f0) and the vocal tract length (VTL) which influences formant frequencies. Based on a natural utterance these parameters were expl...
متن کاملReduced visual discrimination in cochlear implant users.
The aim of the study was to investigate low-level visual function in cochlear implant users. Spatial frequency discrimination was assessed in 16 adults with normal hearing and 18 adults with profound deafness who had a cochlear implant. Thresholds were measured with sinusoidal gratings using a two-alternative temporal forced-choice procedure combined with an adaptive staircase. Cochlear implant...
متن کاملThe Cochlear Implant
The studies on cochlear implants have been conducted in the United States, Austria, Brasil, France, Finland, and some other countries. Up to now, this technique does not seem to have a wide spread application. Indeed it can only apply cases of deafness still presenting sufficient neural remnants to transmit the message. Moreover, the patient must be totally deaf( quasi complete loss of har cel...
