Absolute Spearman correlation value between measure and HAMD score. The individual phone correlation bars correspond to the maximum absolute correlation between depression assessment score and a single phone-specific average length; the specific phone used is shown at each bar. The phone combination correlation bars show the absolute correlation value between assessment score and the signed aggregate phone length; the phones used for this aggregate length are listed in the first column of Table 3. Global speaking rate correlation values from Table 1 are included for comparison.
