Abstract
In this paper, we examine whether the sensitivity of the human cortex to reductions in speech quality is visible in the electroencephalogram (EEG) and whether such measures can be used to enhance behavioral assessments of speech quality. We degraded a speech stimulus (the vowel /a/) in a scalable manner and collected behavioral ratings. Simultaneously, brain activity was recorded using EEG. We trained classifiers that were able to distinguish between events that appeared similar at the behavioral level (i.e., no button press), but where neural responses indicated that noise contamination had been detected—suggesting a possible impact on long-term satisfaction with the transmission quality.
