ABSTRACT
The temporal envelope of speech contains low-frequency information, which is crucial for speech comprehension. This information is essential for identification of phonemes, syllables, words, and sentences (Rosen, 1992). The temporal envelope of speech defines slow variations of the spectral energy of a spoken sentence, variations that are usually below 8 Hz (Houtgast & Steeneken, 1985). Comprehension of speech depends on the integrity of its temporal envelope between 4 and 16 Hz (Drullman et al., 1994; van der Horst et al., 1999). The mechanisms by which this information is extracted and processed are not yet known.
