| Abstract(in English) | We proposed and evaluated an estimation method for the forced selection Japanese Diagnostic Rhyme Test (DRT). The proposed measure takes into account the forced selection manner of the DRT from a pair of rhyming words. The objective distance measure used was based on the Articulation index Band Correlation (ABC). In this measure, the correlation of time-frequency patterns between the test word and the template word speech of the two words in the candidate word pair is calculated. The word with the higher correlation is chosen as the likely candidate word. The ratio of AI bands where higher correlation is shown for the candidate word vs. the total number of bands is calculated to quantify how well the test word matches the candidate word in the word pair. We estimated a logistic mapping function from this ratio to intelligibility scores using speech mixed with known noise. The trained mapping function was then used to estimate the intelligibility of speech mixed with unknown noise. This estimation was compared to estimation using the frequency-weighed segmental SNR, and was proven to be more accurate, with the correlation between estimated and estimated intelligibility over 0.93, and the root mean square below 0.14. Thus, we believe it will be possible to screen" the intelligibility in many of the noise conditions to be tested, and cut down on the scale of the subjective test needed. |
