Application of the Envelope Difference Index to spectrally-sparse speech

摘要

BackgroundAmplitude compression is a common hearing aid processing strategy that can improve speech audibility and loudness comfort but also has the potential to alter important cues carried by the speech envelope. In our previous work, a measure of envelope change, the Envelope Difference Index (EDI; ) was moderately related to recognition of spectrally-robust consonants. This follow-up study investigated the relationship between the EDI and recognition of spectrally-sparse consonants.
