Effects of Enhancement of Spectral Changes on Speech Quality and Subjective Speech Intelligibility

Most information in speech is carried in the spectral changes over time, rather than in static spectral shape per se. The present study presents a preliminary assessment of the possible benefits for speech intelligibility of enhancing spectral changes across time, using behavioral tests with both normal-hearing and hearing-impaired subjects. Ratings of speech quality and intelligibility were obtained using several variants of the processing scheme, with different processing parameters. The results suggest that the processing strategy may have advantages for hearing-impaired people, for certain sets of parameter values.
