“…Therefore, the results obtained in this study are similar to those found in the literature, 7,13,14,17 that report decreased intelligibility with the increase of time-compression, a gradual fall of the averages of correct responses at compression levels until the 60% level, and lower averages of correct responses at 70% time-compression.…”

“…Some factors collaborated for the lower intelligibility in the 70% timecompression, and among them was the fact that the individual has to form, test, and reject several hypotheses in the search for the correct word, which is in agreement with the findings of Friedman and Johnson; 10 additionally, participants have to be more alert and vigilant during the evaluation, since the most compressed lists present increased distortion and decreased redundancy. Katz and Wilde (1985), 12 also reported The list with highest average of correct responses was the disyllable list with 50% time-compression, which was thus the easiest list and the one with the highest degree of intelligibility.Therefore, the results obtained in this study are similar to those found in the literature, 7,13,14,17 that report decreased intelligibility with the increase of time-compression, a gradual fall of the averages of correct responses at compression levels until the 60% level, and lower averages of correct responses at 70% time-compression.In auditory training programs, the average of correct responses should be between 30% and 70% to maintain the patient's motivation, ie, so that the test is not too easy nor too difficult to the point of not maintaining a challenge to the brain. …”

“…Auditory closure ability can be developed and improved through auditory training, and presentation of compressed speech with lower compression degrees before the higher ones may improve the understanding of modified stimuli, and consequently the average number of correct responses obtained. [15][16][17][18] It is also possible to observe an improvement in the performance of the second ear tested in relation to the first one, which could be explained by the learning of the task through the previous experience of the first ear tested. In the easier condition, individuals use more acoustic clues than in the harder condition; in the harder condition, auditory processing prevails in the auditory closure ability.…”

Rabelo CM, Schochat E. Time-compressed speech test in brazilian portuguese. Clinics. 2007;62(3):261-72. INTRODUCTION:The time-compressed speech test has existed since the 1970s. It is sensitive for evaluating auditory closure. However, it is not used in Brazil because until recently, it had not been developed in Portuguese. PURPOSE: To develop a compressed speech test in Portuguese, to apply it to normal-hearing adults, and to verify which of the compressed lists (50%, 60%, or 70%) is the most appropriate to be part of a set of auditory processing tests. METHODS: 144 normal-hearing adults, distributed homogeneously between both genders, were assessed. The compressed speech tests were applied using monosyllables and disyllables according to 8 previously established sequences, and the results were compared with respect to the initial ear, to the order of presentation, and to the kind of test. RESULTS: There were no significant differences between ears. The 50%, 60% and 70% presentation order produced a better average of correct responses than the 70%, 60% and 50% one. There was a significant difference (P <.001) between the results of the tests comprising lists of monosyllables compared to those comprising disyllables. In both tests (with monosyllables and disyllables) the average of correct responses decreased as the compression increased. CONCLUSION: The monosyllabic and disyllabic lists with 60% compression appeared to be more stable than the others, with the average of correct responses around 90%.KEYWORDS: Speech perception. Hearing tests. Speech discrimination tests. Speech intelligibility. INTRODUCTIONThe communication process among individuals happens more efficiently when the individual who speaks is able to express himself adequately, and the one who hears is able to understand what is being said.In the hearing and decoding process of what is being said, an interrelation between the integrity of the peripheral auditory system ("the hearing") and the central auditory system ("the decoding") is observed. The abilities to process the hearing information, the auditory processing abilities, have been observed to be very important for effective communication.Auditory processing studies explore the abilities involved in the interpretation of the sound stimulus and the involvement of several mechanisms of the auditory system that are responsible for processing verbal and nonverbal stimuli. 1In 1992, Stecker reported that audiologists have developed unique methods for the evaluation of auditory processing disorders, such that the auditory system functioning may be evaluated in an adequately controlled environment with careful use of the desired stimulus. Nowadays, there is a great variety of tests for the evaluation of the auditory processing. However, it is difficult to determine which test should be applied in order to obtain a conclusive diagnosis. In the evaluation of the auditory processing, both monotic and dichotic tests are used. The first studies are from 1957, when Callearo and Lazaroni studied speech i...

“…Moreover, all subjects obtained scores considerably poorer than those reported for normal adult listeners, whose mean score was above 90% (Beasley, Forman and Rintelmann, 1973) . The present study supports the finding (Beasley, Maki and Orchik, 1976) that time compression has a more adverse effect on intelligibility scores for children than for adults.…”

“…Thus, caution should be exercised when interpreting children's discrimination scores using adult norms. Beasley, Maki and Orchik (1976) provide normative soundfield data for children age 3.5 to 8.5 on open set SO-word speech discrimination lists (PB-KSO) and closed set Word Intelligibility by Picture Identification (WIPI) material compressed at 0%, 30%, and 60%. Their data revealed that as time compression increased, word intelligibility decreased, with the poorest discrimination scores occurring at 60% compression.…”

Central auditory processing in children with a history of chronic middle ear problems

The purpose of this study was to investigate the Qentral auditory processing of children who had sustained chronic middle ear problems during their early language-learning years. A 60% compressed recording of the NU-6 speech discrimination word lists was administered to twenty eight and nine year old normal hearing public school children, reported by their parents to have qad repeated middle ear problems during their early years, and to twenty control subjects matched for age from the same public schopl classes. · Differences in compressed and uncompressed word discrimination scores between the experimental and control groups were not found to be statistically significant. These results indicate that the experimental subjects' ability to process compressed speech was not impaired by early middle ear difficulties. The alternative was suggested that if these children actually sustained central damage due to distorted or degraded input during their hearing deficit episodes, then such effects may be neutralized by subsequent auditory exerience and neurological maturity. A significant difference for both groups of children was noted between scores obtained with NU-6 lists 2A and 3A at 60% compression. While apparently equivalent in the uncompressed form, list 3 was found to ~e significantly ~ore difficult than list 2 when compressed. Implications for further research are discussed.
