| Summary: | The objective of this study was to develop and evaluate the Polish digit triplet test for
speech intelligibility screening. The first stage of the work deals with the preparation of the test
and the recording procedure. The second part presents results of the digit triplets intelligibility
measurement and retest data. The test consists of 4 statistically equivalent and phonemically
balanced lists, each containing 25 different triplets. The constant stimuli paradigm was used
to determine the digit triplet psychometric functions. Fifty otologically normal subjects took
part in the measurements. The mean list-specific SRT and $S_{50}$ for Polish digit triplet test
are −9.4 dB and 19.7%/dB, respectively, and correlate very well with analogous parameters
obtained for German digit triplet test, i.e. −9.3 dB and 19.6%/dB. The Polish digit triplet test
evaluated in retest experiments revealed high reliability and accuracy for a fast intelligibility
screening. |
