Table 1.
IPA transcriptions, Chinese characters and English translations of the 24 disyllabic word test items from the three test sets, which address “animals”, “body parts and clothing items” and “everyday objects”.
Fig 1.
A sample screen from the “body parts & clothing items” testing set.
After the spoken word was presented via the loudspeaker and the participant responded by touching one of eight pictures on the screen, a yellow frame surrounding the selected picture would blink to highlight the selection; in this sample, the word was /jɛnˇ tɕɪŋˉ/, meaning “eyes” and corresponding to the Chinese characters“眼睛”.

Signal-to-noise ratio for 50% correct scores (SNR-50%, dB SNR) obtained from the Speech Front/Noise Side (NS) and Speech Front/Noise Front conditions (NF) and the spatial release from masking (SRM) values yielded from the two conditions.
