American Four Alternative Auditory Feature test (AFAAF)
The American Four Alternative Auditory Feature test (AFAAF) is the American dialect version of the original Four Alternative Auditory Feature test (FAAF) developed by Foster and Haggard (1987) in the UK. The AFAAF is a closed-set monosyllabic word recognition test designed to evaluate a listener’s speech recognition performance. It comprises 80 test words and 5 practice words. There are five pre-determined randomizations for the 80 test words which minimize response sequence learning effects on repeated presentation of the test. In each test utterance, the key word is embedded in a carrier sentence: “Can you hear ____ clearly?” For each utterance, the test subject listens to the presentation and selects the word he or she hears from four displayed alternatives. The AFAAF can be administered in quiet or in the presence of masking noises. The scoring can produce percentage correct scores for initial consonants, final consonants, or whole words.
Obtaining audio files for the AFAAF
Format: The audio files are in WAV format. The files include (1) the 80 test words and the 5 practice words; (2) modulated and unmodulated masking noises; and (3) calibration signals. Details of the audio files and the word lists for the 5 randomizations are provided in the downloadable PDF document: Test material manual.
Instructions for Purchasing Administration Software:
AFAAF administration and scoring software can be purchased from the AUSP Software Group at the School of Communication Sciences and Disorders at the University of Memphis.
Format: AFAAF for Windows version 1.0 scoring/administration software is available for purchase.
Tips: For test administration software to work properly the 90 audio files in the downloadable package at right need to be copied to the folder "AFAAFSP" in the AFAAF software directory after installation.
