“…For instance, missing acoustic information can be extrapolated using lexical, semantic and/or syntactic information. Approaches for measuring macroscopic speech intelligibility range from presenting syntactically diverse meaningful sentences as in the "hearing in noise test" (e.g., Nilsson et al, 1994;Nielsen and Dau, 2011) and the "conversational language understanding evaluation" (Nielsen and Dau, 2009) to using matrix sentence tests (e.g., Hagerman, 1982;Wagener et al, 2003), where semantically unpredictable sentences are presented within a fixed syntactical structure. Therefore, macroscopic speech intelligibility tests differ in the semantic and syntactic predictability provided, while lexical effects play a considerable role in any of these tests.…”

Responses obtained in consonant perception experiments typically show a large variability across stimuli of the same phonetic identity. The present study investigated the influence of different potential sources of this response variability. It was distinguished between source-induced variability, referring to perceptual differences caused by acoustical differences in the speech tokens and/or the masking noise tokens, and receiver-related variability, referring to perceptual differences caused by within- and across-listener uncertainty. Consonant-vowel combinations consisting of 15 consonants followed by the vowel /i/ were spoken by two talkers and presented to eight normal-hearing listeners both in quiet and in white noise at six different signal-to-noise ratios. The obtained responses were analyzed with respect to the different sources of variability using a measure of the perceptual distance between responses. The speech-induced variability across and within talkers and the across-listener variability were substantial and of similar magnitude. The noise-induced variability, obtained with time-shifted realizations of the same random process, was smaller but significantly larger than the amount of within-listener variability, which represented the smallest effect. The results have implications for the design of consonant perception experiments and provide constraints for future models of consonant perception.

“…To quantify the performance of the blind classification, the hit rate minus the false-alarm rate (H-FA) was computed by comparing the detection of direct-sound components to the short-term SRR classification in the seven frequency channels. Clean training sentences from the Danish hearing in noise test corpus (Danish HINT) (Nielsen and Dau, 2011) were randomly selected and convolved with BRIRs corresponding to room A and room B from the Surrey database (Hummersone et al, 2010). The Surrey database was recorded with a Cortex head and torso simulator (HATS).…”

Fast-acting hearing-aid compression systems typically distort the auditory cues involved in the spatial perception of sounds in rooms by enhancing low-level reverberant energy portions of the sound relative to the direct sound. The present study investigated the benefit of a direct-sound driven compression system that adaptively selects appropriate time constants to preserve the listener's spatial impression. Specifically, fast-acting compression was maintained for time-frequency units dominated by the direct sound while the processing of the compressor was linearized for time-frequency units dominated by reverberation. This compression scheme was evaluated with normal-hearing listeners who indicated their perceived location and distribution of sound images in the horizontal plane for virtualized speech. The experimental results confirmed that both independent compression at each ear and linked compression across ears resulted in broader, sometimes internalized, sound images as well as image splits. In contrast, the linked direct-sound driven compression system provided the listeners with a spatial perception similar to that obtained with linear processing that served as the reference condition. The independent direct-sound driven compressor created a sense of movement of the sound between the two ears, suggesting that preserving the interaural level differences via linked compression is advantageous with the proposed direct-sound driven compression scheme.

“…При выполнении речевой аудиометрии посредством фраз максимальная разборчивость достигается при меньших уровнях интен-сивности, что позволяет определять пороги восприятия речи точнее и эффективнее, чем при использовании от-дельных слов [7,8]. Для тестирования могут предъявлять-ся два типа фраз: смысловые, взятые из жизненных ситуа-ций, с нефиксированной грамматической структурой [9,10], и фразы с так называемой матриксной структурой, синтаксически фиксированные, но семантически непред-сказуемые, формируемые путем комбинации слов в слу-чайном порядке [11][12][13]. Предложения матриксного типа вследствие отсутствия в них смыслового содержания трудны для запоминания, что позволяет многократно те-стировать пациента при аудиологическом обследовании в процессе лечения и реабилитации.…”
