Here's a thread about a nice student-led project on vowel perception that evolved into a full conference paper for Forum Acusticum 2026 in Graz. #FA2026
We explored how listeners mentally represent vowels, i.e. which acoustic properties are most critical for identification. https://hal.science/hal-05679708v1/document

This adaptive method efficiently probes the mental distribution of vowels: after convergence, we can map the distributions along any dimension.
The plot below shows clear, vowel-specific clusters in the F1-F2 space. Different vowels correspond to different regions of the mental space. (5/6)

Vowels are complex: they are defined by multiple acoustic parameters (formants F1-F4, pitch, duration, etc.). But which cues does the auditory system actually rely on during comprehension? While the classic vowel diagram provides a starting point, it is derived from production data rather than perceptual judgments. We need a smarter approach to explore the high-dimensional perceptual space of vowe

This results in chains of selected sounds that converge toward a prototypical representation of the target vowel in the acoustic space. (4/6)
