摘要：

The effect of speech processing on articulatory-feature recognition was studied in a group of hearing-impaired listeners with high-frequency sensorineural losses. Individual difference scaling (INDSCAL) and sequential information analysis (SINFA) were applied to a set of consonant-vowel-consonant responses measured under various conditions of speech processing. The processing consisted of high-frequency phonemic compression combined with compensation for anti-upward-spread-of-masking (i.e. anti-USOM). In quiet, we found an improved recognition of frication with compression, whereas additional anti-USOM improved the recognition of the second and third vowel-formants. In background noise, we found remarkably negative effects of anti-USOM on the recognition of features containing low-frequency cues, such as voicing and nasality. We conclude that the combined results of SINFA and INDSCAL provide important insights into the possibilities and limitations of phonemic compression and anti-USOM.
