“…Although seemingly similar to EEQ processing, there are important differences between the two methods. First, many implementations of CV ratio enhancement (e.g, GordonSalant, 1986;Kennedy et al, 1998) require explicit segmentation of speech into consonant and vowel components, or attempt to approximate segmentation using approaches such as detection of voiced versus unvoiced segments (Skowronski and Harris, 2006;Saripella et al, 2011) or cross-frequency-band energy comparisons (Preves et al, 1991). The relative energies from these segments are used to explicitly adjust the CV ratio.…”

The masking release (i.e., better speech recognition in fluctuating compared to continuous noise backgrounds) observed for normal-hearing (NH) listeners is generally reduced or absent in hearing-impaired (HI) listeners. One explanation for this lies in the effects of reduced audibility: elevated thresholds may prevent HI listeners from taking advantage of signals available to NH listeners during the dips of temporally fluctuating noise where the interference is relatively weak. This hypothesis was addressed through the development of a signal-processing technique designed to increase the audibility of speech during dips in interrupted noise. This technique acts to (i) compare short-term and long-term estimates of energy, (ii) increase the level of short-term segments whose energy is below the average energy, and (iii) normalize the overall energy of the processed signal to be equivalent to that of the original long-term estimate. Evaluations of this energy-equalizing (EEQ) technique included consonant identification and sentence reception in backgrounds of continuous and regularly interrupted noise. For HI listeners, performance was generally similar for processed and unprocessed signals in continuous noise; however, superior performance for EEQ processing was observed in certain regularly interrupted noise backgrounds.

“…Regarding speech recognition, studies found reduced speech recognition with expansion when speech was presented at a low level (Walker et al, 1984;Bray and Ghent, 2001;Plyler et al, 2005a;Plyler et al, 2007). In general, when speech was presented at higher levels, equivalent recognition to that of linear amplification tended to occur (Walker et al, 1984;Preves et al, 1991;Sammeth et al, 1996;van Buuren et al, 1999;Bray and Ghent, 2001;Plyler et al, 2005a;Plyler et al, 2007). Only one study contradicts the above findings.…”

“…Nevertheless, the results were sufficiently promising for engineers to investigate methods for improving CVRs automatically using the new tools provided by DSP. 36 Other methods of speech processing involved enhancing the temporal structure of speech so as to reduce the masking of weak sounds by more intense sounds and, in the case of reverberant speech, to restore the temporal modulations of the speech signal reduced by the temporal smoothing of the reverberation. Experimental evaluations of these techniques yielded mixed results.…”
