Relative contributions of spectral and temporal cues for phoneme recognition.
Cochlear implants provide users with limited spectral and temporal information. In this study, the amount of spectral and temporal information was systematically varied through simulations of cochlear implant processors using a noise-excited vocoder. Spectral information was controlled by varying the number of channels between 1 and 16, and temporal information was controlled by varying the low...
متن کاملRelative Contributions of Spectral and Temporal Cues to Korean Phoneme Recognition
This study was aimed to evaluate the relative contributions of spectral and temporal information to Korean phoneme recognition and to compare them with those to English phoneme recognition. Eleven normal-hearing Korean-speaking listeners participated in the study. Korean phonemes, including 18 consonants in a /Ca/ format and 17 vowels in a /hVd/ format, were processed through a noise vocoder. T...
متن کاملSpectral and temporal cues for phoneme recognition in noise.
Cochlear implant users receive limited spectral and temporal information. Their speech recognition deteriorates dramatically in noise. The aim of the present study was to determine the relative contributions of spectral and temporal cues to speech recognition in noise. Spectral information was manipulated by varying the number of channels from 2 to 32 in a noise-excited vocoder. Temporal inform...
متن کاملTemporal and spectral cues in Mandarin tone recognition.
This study evaluates the relative contributions of envelope and fine structure cues in both temporal and spectral domains to Mandarin tone recognition in quiet and in noise. Four sets of stimuli were created. Noise-excited vocoder speech was used to evaluate the temporal envelope. Frequency modulation was then added to evaluate the temporal fine structure. Whispered speech was used to evaluate ...
متن کاملSpectral and temporal cues for speech recognition: implications for auditory prostheses.
Features of stimulation important for speech recognition in people with normal hearing and in people using implanted auditory prostheses include spectral information represented by place of stimulation along the tonotopic axis and temporal information represented in low-frequency envelopes of the signal. The relative contributions of these features to speech recognition and their interactions h...
