    The intelligibility of chimeric locally time-reversed speech was investigated. Both (1) the boundary frequency between the temporally degraded band and the non-degraded band and (2) the segment duration were varied. Japanese mora accuracy decreased if the width of the degraded band or the segment duration increased. Nevertheless, the chimeric stimuli were more intelligible than the locally time-reversed controls. The results imply that the auditory system can use both temporally degraded speech information and undamaged speech information over different frequency regions in the processing of the speech signal, if the amplitude envelope in the frequency range of 840-1600 Hz was preserved.
