“…Nevertheless, higher-order processing operations depend on the extraction of syllables from the acoustical signal based on the analysis of the acoustic features that make up each utterance. Indeed, evidence from older subjects suggests that syllable discrimination skills correlate directly with verbal memory performance when cognitive factors are controlled [63][64]. This finding supports the notion that perceptual success of HA users comes at the cost of the extra effort that is needed for analyzing phonemes and might otherwise be available for analyzing sentence content.…”

Abstract-We assessed the effects of perceptual training of syllable identification in noise on nonsense syllable test (NST) performance of new (Experiment 1) and experienced (Experiment 2) hearing aid (HA) users with sensorineural hearing loss. In Experiment 1, new HA users were randomly assigned to either immediate training (IT) or delayed training (DT) groups. IT subjects underwent 8 weeks of at-home syllable identification training and in-laboratory testing, whereas DT subjects underwent identical in-laboratory testing without training. Training produced large improvements in syllable identification in IT subjects, whereas spontaneous improvement was minimal in DT subjects. DT subjects then underwent training and showed performance improvements comparable with those of the IT group. Training-related improvement in NST scores significantly exceeded improvements due to amplification. In Experiment 2, experienced HA users received identical training and testing procedures as users in Experiment 1. The experienced users also showed significant training benefit. Trainingrelated improvements generalized to untrained voices and were maintained on retention tests. Perceptual training appears to be a promising tool for improving speech perception in new and experienced HA users.

“…In some cases listeners may score highly on speech recognition tasks, but report that substantial "mental effort" was required to complete the task (Anderson Gosselin & Gagné, 2010). McCoy et al (2005) provided quantitative evidence of this effect, finding that for participants with mild-to-moderate hearing loss the increased perceptual effort required to decipher words produced notable effects on recall performance. Hearing impairment (McCoy, et al, 2005), age (e.g., Larsby, Hallgren, Lyxell, & Arlinger, 2005), and listening environment all play a role in influencing the degree of perceived listening effort.…”

Purpose: Older adults exhibit difficulty understanding speech that has been experimentally degraded. Age-related changes to the speech mechanism lead to natural degradations in signal quality. We tested the hypothesis that older adults with hearing loss would exhibit declines in speech recognition when listening to the speech of older adults, compared with the speech of younger adults, and would report greater amounts of listening effort in this task.Methods: Nineteen individuals with age-related hearing loss completed speech recognition and listening effort scaling tasks. Both were conducted in quiet, when listening to high and low predictability phrases produced by younger and older speakers respectively.Results: No significant difference in speech recognition existed when stimuli were derived from younger or older speakers. However, perceived effort was significantly higher when listening to speech from older adults, as compared to younger adults. Conclusions:For older individuals with hearing loss, natural degradations in signal quality may require greater listening effort. However, they do not interfere with speech recognition -at least in quiet. Follow-up investigation of the effect of speaker age on speech recognition and listening effort under more challenging noise conditions appears warranted.

“…For example, studies on the cognitive impact of hearing loss in elders (e.g., McCoy et al, 2005; have suggested that even when the speech signal is correctly identified by listeners with a mild-to-moderate hearing loss, the perceptual and cognitive efforts required for successful word recognition may take a toll on processing resources that might otherwise be used for subsequent processing (e.g., for encoding the speech content into memory). Systematic research on the differential impact of perceptual and cognitive load in speech segmentation is only now emerging, and the consequences of such an approach seem to go far beyond the segmentation domain.…”

MaterialAL material. To achieve realistic coarticulation, we used naturally produced utterances rather than synthesized speech, and created concatenated and coarticulated versions of the AL stimuli (for the detailed method, see Fernandes et al., 2007). On the basis of Fernandes et al.'s pretests, we already know that the use of naturally produced rather than synthesized utterances does have an impact on ALL performance.All the natural speech stimuli were recorded in a soundproof room (using WaveLab Lite Program, version 2.52) by a European Portuguese female native speaker using a Shure M58 microphone and sampled at a rate of 22.05 kHz with 16-bit conversion. Adobe Audition 1.5 and Praat 4.2.24 (available at http://fon.hum.uva.nl/ praat/) were used for editing of the digitized versions of the stimuli (i.e., syllables, words, and part-words). These stimuli were closely matched to a synthesized stream in all relevant acoustic parameters, such as speaking rate (approximately 270 syllables per minute), AL stimuli duration, lack of lexical stress cues to word boundaries, and pitch contour (through flattening to monotone 220 Hz).The AL used by Fernandes et al. (2007) was adopted here. It was constituted by six trisyllabic AL words (i.e., / /, / /, / /, / /, / /, / /). TPs between adjacent syllables were always higher within than between AL words. Half of the AL words had higher TPs (high-TP words, ranging from .75 to 1) than the other half (low-TP words, ranging from .50 to .58), but all occurred with the same frequency in the AL stream.
