Although Central Institute for the Deaf (CID) W-1 stimuli are routinely used for speech recognition threshold (SRT) testing, they are not always familiar to new learners of English and often lead to erroneous assessments. To improve test accuracy, alternative stimuli were constructed by pairing familiar English digits. These digit pairs were used to measure SRT for 12 non-native speakers of English and 12 native speakers of English. Results indicate that digit pairs effectively measure SRT for both participant groups; and more importantly, for non-native speakers of English, digit pairs are more accurate than CID W-1 words in measuring the hearing threshold for speech. Digit-pairs have cross-linguistic appeal and should greatly facilitate accurate SRT testing for listeners with minimal exposure to English.
