Spatial release from masking with noise-vocoded speech.
This study investigated how confusability between target and masking utterances affects the masking release achieved through spatial separation. Important distinguishing characteristics between competing voices were removed by processing speech with six-channel envelope vocoding, which simulates some aspects of listening with a cochlear implant. In the first experiment, vocoded target nonsense ...
متن کاملFactors affecting masking release in cochlear-implant vocoded speech.
Cochlear-implant (CI) listeners generally perform better when listening to speech in steady-state noise than in fluctuating maskers, and the reasons for that are unclear. The present study presents a new hypothesis for the observed absence of release from masking. When listening to speech in fluctuating maskers (e.g., competing talkers), CI users cannot fuse the pieces of the message over tempo...
متن کاملToddlers' recognition of noise-vocoded speech.
Despite their remarkable clinical success, cochlear-implant listeners today still receive spectrally degraded information. Much research has examined normally hearing adult listeners' ability to interpret spectrally degraded signals, primarily using noise-vocoded speech to simulate cochlear implant processing. Far less research has explored infants' and toddlers' ability to interpret spectrally...
متن کاملRole of binaural hearing in speech intelligibility and spatial release from masking using vocoded speech.
A cochlear implant vocoder was used to evaluate relative contributions of spectral and binaural temporal fine-structure cues to speech intelligibility. In Study I, stimuli were vocoded, and then convolved through head related transfer functions (HRTFs) to remove speech temporal fine structure but preserve the binaural temporal fine-structure cues. In Study II, the order of processing was revers...
متن کاملInformational masking in young and elderly listeners for speech masked by simultaneous speech and noise.
Three experiments measured the effects of age on informational masking of speech by competing speech. The experiments were designed to minimize the energetic contributions of the competing speech so that informational masking could be measured with no large corrections for energetic masking. Experiment 1 used a "speech-in-speech-in-noise" design, in which the competing speech was presented in n...
