CIRCE Italian and English Experimental Stimuli Sets

This dataset contains the experimental speech stimuli sets developed within the CIRCE project for perceptual experiments on accent perception and discrimination carried out in Italy.The dataset includes audio files used in the CIRCE experiments, created by combining individual speech recordings from the CIRCE Italian Speech Stimuli Corpus and the CIRCE English Speech Stimuli Corpus into predefined sequences corresponding to specific experimental settings. Different stimulus sets reflect different ordering and grouping of the same underlying speech materials.The dataset documents the exact audio stimuli presented to participants in the CIRCE experiments to investigate students' attitudes towards L1 and L2 accents of Italian and English. The dataset is intended to support transparency, replicability, and methodological reuse in educational and social research contexts. It is part of the CIRCE Zenodo community.
