*: Original LTT submission achieved low accuracy due to a bug in a Matlab toolbox - original results are presented in brackets.

Figure: Classification accuracy(%) for the SC task. Plot shows mean over 5-fold cross-validation with 95% confidence intervals. Dashed lines indicate (left to right): chance performance (black); baseline system performance (light blue); mean accuracy of human listener (orange). “Majority vote” is a meta-classifier using the majority decision over all submissions. Original LTT submissions shown in light gray.
