15th International Congress of Phonetic Sciences (ICPhS-15)
The power of traditional vowel classification is known to be moderate, leading especially in phonetic transcription to ambiguous classifications. A common auditory reference system - shared by all transcribers - might improve inter- and intra-speaker agreements. In order to suggest a first auditory subsystem, a series of auditory experiments was carried out with 35 of the world's leading phoneticians. They were asked to define their auditory concepts of primary vowel types by adjusting a vowel synthesiser. Mean values and standard deviations for the F1/F2-combinations are presented for three expert groups differing in their present IPA-usage. The criterion of auditory equidistance is examined statistically. Bias-effects due to listeners' transcription traditions and mother tongues are discussed and the assumption of a continuous perception mode for vowels is challenged.
