This dataset contains the synthetic stimuli used in the study published in the paper "A Comparative Study of 3D and 1D Acoustic
Simulations of the Higher Frequencies of Speech". The goal of this study was to evaluate the accuracy of the acoustic wave
propagation in the vocal tract in a source-filter synthesis paradigm with two perceptual experiments. The high frequencies (above 4 kHz) of the stimuli were
generated by three different methods: a source-filter method relying on a 1D and a 3D acoustic model, and a bandwith extension
