Relationship between contributions of temporal amplitude envelope of speech and modulation transfer function in room acoustics to perception of noise-vocoded speech

Speech signals can be represented as a sum of amplitude-modulated frequency bands. This sum can also be regarded as a temporal amplitude envelope (TAE) with temporal fine structure. Our previous studies using noise-vocoded speech (NVS) showed that the TAE of speech plays an important role in the perception of linguistic information (speech intelligibility) as well as non-linguistic information (e.g., vocal-emotion recognition). It was found that...
