“…By increasing the CVR, the current method amplified the weak energy in the consonant, but maintained the vowel energy at a constant level. Increased consonant energy can improve consonant identity in a number of ways, including reducing the backward masking of the consonant by the vowel (Danaher and Pickett, 1975;Danaher et al, 1978), increasing the effective S?C of the consonant relative to the background competition, or by a combination of these two factors. The enhancement in speech-recognition performance observed with the C modification is consistent with earlier findings indicating improvements in speech intelligibility with increases in the CVR.…”

The purpose of this study was to evaluate the efficiency of three acoustic modifications derived from clear speech for improving consonant recognition by young and elderly normal-hearing subjects. Percent-correct nonsense syllable recognition was measured for four stimulus sets: unmodified stimuli; stimuli with consonant duration increased by 100%; stimuli with consonant-vowel ratio increased by 10 dB; and stimuli with both consonant duration and consonant-vowel ratio increased. Analyses of overall nonsense syllable recognition, consonant feature recognition, and consonant confusion patterns demonstrated that the consonant-vowel ratio increase modification produced better performance than the other acoustic modifications by both subject groups. However, elderly subjects exhibited poorer performance than young subjects in most conditions. These results and their implications are discussed.

“…That suggestion is strikingly similar to recent ones for second-language learners, who have been described as "overweighting" redundant cues, which occurs when the typical cues are not ones listeners learned to weight in their first language (Llanos, Dmitrieva, Shultz, & Francis, 2013). Another relevant trend is that the weighting of acoustic cues for listeners with hearing loss can vary across listeners with similar audiometric profiles (e.g., Danaher, Wilson, & Pickett, 1978). Thus, there is ample evidence from a variety of populations that listeners can, and do, vary in terms of the perceptual weighting strategies employed to make phonemic decisions, and this variability cannot be explained strictly by auditory sensitivity.…”
