Summary

Familiar digit pairs improve speech recognition threshold (SRT) testing accuracy for non-native English speakers compared to traditional Central Institute for the Deaf (CID) W-1 words. This method offers a more reliable hearing assessment for diverse language learners.

Area of Science:

Audiology
Speech-Language Pathology
Linguistics

Background:

Central Institute for the Deaf (CID) W-1 stimuli are standard for speech recognition threshold (SRT) testing.
These stimuli may not be familiar to non-native English speakers, potentially causing inaccurate hearing assessments.

Purpose of the Study:

To evaluate the effectiveness of familiar English digit pairs as alternative stimuli for SRT testing.
To compare the accuracy of digit pairs versus CID W-1 words for non-native English speakers.

Main Methods:

Familiar English digit pairs were created as alternative auditory stimuli.
Speech recognition thresholds (SRTs) were measured using both digit pairs and CID W-1 words.
Participants included 12 non-native English speakers and 12 native English speakers.

Main Results:

Digit pairs proved effective for SRT measurement in both native and non-native English speakers.
Digit pairs demonstrated higher accuracy than CID W-1 words for non-native English speakers in determining hearing thresholds for speech.

Conclusions:

English digit pairs offer a more accurate and accessible method for SRT testing, particularly for individuals with limited English proficiency.
The cross-linguistic appeal of digit pairs can enhance the reliability of hearing assessments for a broader range of listeners.
