Time-frequency representations of the six targets used in the experiment, organized by distinctive features. The time and frequency resolutions are the same as those used for the analysis. Warmer regions indicate higher amplitudes in a logarithmic scale. The white traces indicate the fundamental frequency (\(f_0\)) and formant trajectories (F1-F4).
