Vowel identification tests use short 180 ms synthesized tokens at roving levels

Evidence

Vowel stimuli consisted of eight long vowels ‘baat’, ‘baeaet’, ‘beet’, ‘biit’, ‘boeoet’, ‘boot’, ‘bueuet’, ‘buut’. All vowels had a very similar duration of around 180 ms. The stimuli were uttered by a woman. An 8-alternative forced choice task procedure 8-AFC was created where 2 and 4 repetitions of each vowel were used for training and testing respectively. The vowels were presented at the same 60 dB SPL level as the spectral ripples with a loudness roving of +/- 1.5 dB. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1848
