“…Harris et al (2003) developed Korean monosyllabic word lists and found that the mean slope was 5.0%/dB for a male talker and 5.1%/dB for a female talker. Harris et al (2004) also developed monosyllabic materials for native Polish speakers. The lists were found to have mean slopes of 5.8%/dB for a male speaker and 5.9%/dB for a female speaker.…”

In this study, monosyllabic Mandarin speech test materials (MSTMs) were developed for use in word recognition tests for speech audiometry in Chinese audiology clinics. Mandarin monosyllabic materials with high familiarity were designed with regard to phonological balance and recorded digitally with a male voice. Inter-list equivalence of difficulty was evaluated for a group of 60 subjects (aged 18-25 years) with normal hearing. Seven lists with 50 words each were found to be equivalent. These seven equivalent lists were used to measure performance-intensity (PI) functions for a group of 32 subjects with normal hearing and a group of 40 subjects with mild to moderate sensorineural hearing loss. The mean slope of PI function was found to be 4.1%/dB and 2.7%/dB, respectively. The seven lists of Mandarin monosyllabic materials were found to have sufficient reliability and validity to be used in clinical situations.

“…The lists were found to have mean slopes of 5.8%/dB for a male speaker and 5.9%/dB for a female speaker. In addition, Harris et al (2007) designed and evaluated monosyllabic materials in Russian. Mean slopes of 5.8%/dB for a male talker and 5.6%/dB for a female talker were reported.…”

“…A possible limitation of the random selection procedure is that the phonemic distribution of the selected set may differ from that of the original matrix. Even though the validity of phonemic balancing as a design criterion for speech tests has been debated ( Martin, Champlin, & Perez, 2000 ; Wang, Mannell, Newall, Zhang, & Han, 2007 ) and some authors have abandoned phonemic balancing in developing speech materials ( Harris et al., 2007 ; Kirk, Pisoni, & Osberger, 1995 ; Nissen, Harris, Jennings, Eggett, & Buck, 2005 ), recent matrix tests in other languages were all developed to be phonemically balanced. Regardless of the validity of phonemic balanced speech materials, for the current optimization it is important that the differences between subset-based sampling and the original matrix test with respect to the phonemic distributions remain relatively small.…”

Optimization of the Dutch Matrix Test by Random Selection of Sentences From a Preselected Subset

Matrix tests are available for speech recognition testing in many languages. For an accurate measurement, a steep psychometric function of the speech materials is required. For existing tests, it would be beneficial if it were possible to further optimize the available materials by increasing the function’s steepness. The objective is to show if the steepness of the psychometric function of an existing matrix test can be increased by selecting a homogeneous subset of recordings with the steepest sentence-based psychometric functions. We took data from a previous multicenter evaluation of the Dutch matrix test (45 normal-hearing listeners). Based on half of the data set, first the sentences (140 out of 311) with a similar speech reception threshold and with the steepest psychometric function (≥9.7%/dB) were selected. Subsequently, the steepness of the psychometric function for this selection was calculated from the remaining (unused) second half of the data set. The calculation showed that the slope increased from 10.2%/dB to 13.7%/dB. The resulting subset did not allow the construction of enough balanced test lists. Therefore, the measurement procedure was changed to randomly select the sentences during testing. Random selection may interfere with a representative occurrence of phonemes. However, in our material, the median phonemic occurrence remained close to that of the original test. This finding indicates that phonemic occurrence is not a critical factor. The work highlights the possibility that existing speech tests might be improved by selecting sentences with a steep psychometric function.

“…Despite its widely reported clinical value, SRT testing still faces several significant threats to its reliability and validity as a measure of speech reception. Harris et al ( 2007 ) summarised these threats to include the number, type and homogeneity of the words in the test; the accent or dialect of the speaker; and the method and level of stimulus presentation. Panday, Kathard, Pillay and Govender ( 2007 , 2009 ) provided a description of how these threats may be addressed when developing SRT tests.…”

Background and objectivesThis study investigated reliability, particularly the internal and external consistency, of a new isiZulu speech reception threshold (SRT) test.MethodsTo examine internal consistency, 21 adult isiZulu speakers with normal hearing sensitivity completed the SRT test using the first and second halves of the SRT wordlist in the same test session. To examine external consistency, a separate 23 adult isiZulu speakers with normal hearing sensitivity completed the SRT test, using the whole word list on two occasions 4 weeks apart. Consistency of SRT test scores in these test conditions was measured using intraclass correlation coefficient analyses (a measure of the consistency or reproducibility of different observations of the same quantity) and Bland and Altman analyses of agreement (a comparison of measurement error with the expected variation amongst subjects).ResultsIntraclass correlation coefficient values ranged from 0.69 to 0.79, showing the isiZulu test scores were highly consistent between the test and retest conditions used in this study. Bland and Altman analyses showed that isiZulu speakers with normal hearing sensitivity can be expected to return isiZulu SRT test scores that differ by no more than 7.5 dB HL – 8.7 dB HL between original and repeat assessments.ConclusionThe isiZulu SRT test was reliable, showing high internal and external consistency, when used to assess first-language speakers of isiZulu with normal hearing sensitivity. These findings warrant continued development of the isiZulu SRT test for eventual clinical use. This development should include validating this test on first-language speakers of isiZulu with and without hearing loss.
