“…For example, the resolution of consonant place is generally assumed to be based on spectral cues. However, Lindholm et al (1988) recently demonstrated that impaired listeners can often use temporally based cues as an aid to the resolution of consonant place. Any investigation into cue use by the hearing impaired must be careful not to make overly restrictive assumptions as to what phonemic information can be and is used by listeners.…”

“…The available cue set either is or is not sufficient to define the segment unambiguously. Several investigators have attempted to determine how hearing-impaired listeners use specific isolated phonemic cues (Lindholm et al, 1988;Revoile et al, 1985;Revoile et al, 1987). In general, these investigations have indicated that hearing-impaired listeners will often use the available cue set in a manner different from normally hearing listeners.…”

There is limited documentation available on how sensorineurally hearing-impaired listeners use the various sources of phonemic information that are known to be distributed across time in the speech waveform. In this investigation, a group of normally hearing listeners and a group of sensorineurally hearing-impaired listeners (with and without the benefit of amplification) identified various consonant and vowel productions that had been systematically varied in duration. The consonants (presented in a /haCa/ environment) and the vowels (presented in a /bVd/ environment) were truncated in steps to eliminate various segments from the end of the stimulus. The results indicated that normally hearing listeners could extract more phonemic information, especially cues to consonant place, from the earlier occurring portions of the stimulus waveforms than could the hearing-impaired listeners. The use of amplification partially decreased the performance differences between the normally hearing listeners and the unaided hearing-impaired listeners. The results are relevant to current models of normal speech perception that emphasize the need for the listener to make phonemic identifications as quickly as possible.

“…People with sensorineural loss that leaves them less able to perceive higher frequency energy typically show better perceptual performance with vowels than with consonants ͑Boothroyd, 1984; Dubno et al, 1982;Lindholm et al, 1988;Zeng and Turner, 1990͒. However, hearing-impaired listeners using cochlear implants tend to perceive consonants more accurately than vowels ͑Fu and Shannon, 1998;Teoh et al, 2003;Välimaa et al, 2002͒.…”

Three experiments tested the hypothesis that vowels play a disproportionate role in hearing talker identity, while consonants are more important in perceiving word meaning. In each study, listeners heard 128 stimuli consisting of two different words. Stimuli were balanced for same/different meaning, same/different talker, and male/female talker. The first word in each was intact, while the second was either intact (Experiment 1), or had vowels ("Consonants-Only") or consonants wels-Only") replaced by silence (Experiments 2, 3). Different listeners performed a same/ different judgment of either talker identity (Talker) or word meaning (Meaning). Baseline testing in Experiment 1 showed above-chance performance in both, with greater accuracy for Meaning. In Experiment 2, Talker identity was more accurately judged from Vowels-Only stimuli, with modestly better overall Meaning performance with Consonants-Only stimuli. However, performance with vowel-initial Vowels-Only stimuli in particular was most accurate of all. Editing Vowels-Only stimuli further in Experiment 3 had no effect on Talker discrimination, while dramatically reducing accuracy in the Meaning condition, including both vowel-initial and consonant-initial Vowels-Only stimuli. Overall, results confirmed a priori predictions, but are largely inconsistent with recent tests of vowels and consonants in sentence comprehension. These discrepancies and possible implications for the evolutionary origins of speech are discussed.

“…Hearing-impaired and normal-hearing adults show differential use of speech recognition cues [24][25][26][27][28][29][30][31][32][33]. In general, hearing-impaired listeners relied less on high-frequency cues preferred by normal-hearing listeners, when hearing loss compromised those cues.…”

Abstract-Acclimatization was studied in hearing-impaired patients with no previous hearing aid (HA) experience who were fit bilaterally with either wide dynamic range multichannel compression (WDRMCC) or linear amplification (LA) HAs. Throughout 40 weeks of normal HA use, we monitored changes in nonsense syllable perception in speech-spectrum noise. Syllable recognition for WDRMCC users improved by 4.6% over the first 8 weeks, but the 2.2% improvement for LA users was complete in 2 to 4 weeks. Consonant confusion analyses indicated that WDRMCC experience facilitated consonant identification, while LA users primarily changed their response biases. Furthermore, WDRMCC users showed greater improvement for aided than unaided stimuli, while LA users did not. These results demonstrate acclimatization in new users of WDRMCC HAs but not in new users of LA HAs. A switch in amplification type after 32 weeks produced minimal performance change. Thus, acclimatization depended on the type of amplification and the previous amplification experience.
