Auditory reverse correlation (revcorr) is an experimental paradigm that reveals the acoustic cues used by listeners in any auditory task. It has been previously used to explore the categorisation of /aba/ and /ada/ sounds in noise. Here, we extend the paradigm to new phonemic contrasts. In a typical revcorr experiment, one introduces random fluctuations in stimuli in order to measure how they affect the behavioural responses of the participant on a trial-by-trial basis. The outcome is called auditory classification images (ACI), i.e. time-frequency maps of the acoustic cues used by participants, revealing their individual listening strategies in a given task. Here, we use the "fastACI toolbox" [Osses & Varnet, 2021] to apply the paradigm to new phonemic contrasts: /aba/-/apa/ ; /ada/-/aga/ ; /ada/-/ata/ ; /apa/-/ata/. It allows us to study the perception of two phonetic traits: place of articulation and voicing. We present the results of 2 participants for each contrast. The results are consistent with the main auditory cues already identified in the psycholinguistic iterature but they also reveal unexpected secondary cues.
