Abstract/OtherAbstract:
|
The present study evaluated the relative contribution of various regions of the frequency spectrum to consonant recognition in normal-hearing listeners. The method used in this study was specifically designed to provide an estimate of the importance of each band (i) consistent with the frequency resolution of the auditory system and (ii) irrespective of the location of information elsewhere in the spectrum. Speech stimuli were divided into 30 adjacent bands with each band corresponding approximately to the bandwidth of an auditory filter. Listeners were presented with a subset of bands to avoid ceiling effects. The importance of each band was derived from the drop in performance observed when that particular band was omitted. The spectral location of the bands was always chosen randomly except for the one band whose importance was being assessed. The results indicated a fairly homogeneous contribution of all 30 bands to consonant recognition (i.e., a flat auditory channel importance function) with only the five lowest bands (below 300 Hz) having lesser weight. In contrast, additional analyses revealed a non-uniform contribution of the bands to the transmission of voicing, manner and place of articulation. [Work supported by NIDCD.]. |
