Enhancing temporal cues to voice pitch in continuous interleaved sampling cochlear implants.
The limited spectral resolution of cochlear implant systems means that voice pitch perception depends on weak temporal envelope cues. Enhancement of such cues was investigated in implant users and in acoustic simulations. Subjects labeled the pitch movement of processed synthetic diphthongal glides. In standard processing, noise carriers (simulations) or pulse trains (implant users) were modula...
متن کاملEnhancement of temporal periodicity cues in cochlear implants: effects on prosodic perception and vowel identification.
Standard continuous interleaved sampling processing, and a modified processing strategy designed to enhance temporal cues to voice pitch, were compared on tests of intonation perception, and vowel perception, both in implant users and in acoustic simulations. In standard processing, 400 Hz low-pass envelopes modulated either pulse trains (implant users) or noise carriers (simulations). In the m...
متن کاملLocalization cues with bilateral cochlear implants.
Selected subjects with bilateral cochlear implants (CIs) showed excellent horizontal localization of wide-band sounds in previous studies. The current study investigated localization cues used by two bilateral CI subjects with outstanding localization ability. The first experiment studied localization for sounds of different spectral and temporal composition in the free field. Localization of w...
متن کاملImportant role of temporal cues in speaker identification for simulated cochlear implants
Speaker identification is still challenging issue for cochlear implant (CI) users due to the poor spectral cue provided by the CI device. To optimize CI systems for the users, it is important to understand the role of temporal modulation cues in speaker identification, as the CI device provides temporal modulation cues as primary cues. This study investigates the relative contributions of spect...
متن کاملContributions of temporal and place cues in pitch perception in absolute pitch possessors.
Pitch perception is determined by both place and temporal cues. To explore whether the manner in which these cues are used differs depending on absolute pitch capability, pitch identification experiments with and without pitch references were conducted for subjects with different absolute pitch capabilities and musical experience. Three types of stimuli were used to manipulate place and tempora...
