Perceptual learning of noise vocoded words: effects of feedback and lexicality.

Speech comprehension is resistant to acoustic distortion in the input, reflecting listeners' ability to adjust perceptual processes to match the speech input. This adjustment is reflected in improved comprehension of distorted speech with experience. For noise vocoding, a manipulation that removes spectral detail from speech, listeners' word report showed a significantly greater improvement ove...

Lexical information drives perceptual learning of distorted speech: evidence from the comprehension of noise-vocoded sentences.

Speech comprehension is resistant to acoustic distortion in the input, reflecting listeners' ability to adjust perceptual processes to match the speech input. For noise-vocoded sentences, a manipulation that removes spectral detail from speech, listeners' reporting improved from near 0% to 70% correct over 30 sentences (Experiment 1). Learning was enhanced if listeners heard distorted sentences...

Oscillations corticales et intelligibilité de la parole dégradée (Oscillatory cortical activity and intelligibility of degraded speech) [in French]

________________________________________________________________________________________________________ Oscillatory cortical activity and intelligibility of degraded speech Many neurocognitive aspects associated with the processing of speech were up to now studied by the analysis of event-related potentials. However, none of these cortical responses can be considered as a direct indicator of s...

Pure linguistic interference during comprehension of competing speech signals.

Speech-in-speech perception can be challenging because the processing of competing acoustic and linguistic information leads to informational masking. Here, a method is proposed to isolate the linguistic component of informational masking while keeping the distractor's acoustic information unchanged. Participants performed a dichotic listening cocktail-party task before and after training on 4-...

Toddlers' comprehension of degraded signals: Noise-vocoded versus sine-wave analogs.

Recent findings suggest that development changes the ability to comprehend degraded speech. Preschool children showed greater difficulties perceiving noise-vocoded speech (a signal that integrates amplitude over broad frequency bands) than sine-wave speech (which maintains the spectral peaks without the spectrum envelope). In contrast, 27-month-old children in the present study could recognize ...
