1 Within-Consonant Perceptual Differences in the Hearing Imired Ear Andrea Trevino* and Jont Allen HSR Research Group University of Illinois Urbana-Chamign
2 Objective: Undersnd how hearing imired (HI) ears perceive the acoustic cues in speech. Methods: 4 Consonant Vowel stimuli ( zero-error, unambiguous) /b, d, f, g, k, m, n, p, s,, t, v, ʒ, z/+/ɑ/ (in plots: Z= ʒ, S= ) 2 lkers for each consonant ( le, fele) Speech Weighted Noise at 4 SNRs (, 6, 2 db, Q) Token - lker & consonant Results: ) HI errors can be conined to a sll subset of tokens ) Tokens of the same consonant can be perceptually different for HI listeners (noise-robustness/confusions) ) Consistencies are observed across NH and HI ears in terms of noise robustness and confusion groups

16 Conclusion There is a correlation between HI and NH consonant perception. Supports the hypothesis that the HI and NH listeners are using the same priry cues.

19 Sumry Multiple tokens of the same consonant can be perceptually different for HI listeners in terms of noise-robustness and confusion groups Systetic behavior on a token basis: - HI and NH listeners show agreement in noise-robustness - Different HI listeners share token-dependent confusions Systetic responses suggest that common cues are being used Consistent (low-entropy) token-specific confusions imply that the HI ears are not guessing
20 Conclusions - The average error can have large amounts of underlying individual token error - Analysis at the token level reveals systetic tterns in the HI confusions - NH psychoacoustic da can characterize the cue variability of individual tokens, providing tools for undersnding HI perception - The role of naturally-occurring conflicting acoustic cues reins unknown (Li et al. 2, 22)
