Summary of Cue Values (Mean and SD) as a Function of Emotion for Acoustic Cues That Differentiated Between Emotions
| Cue | Happy (n = 16) | Sad (n = 16) | Anger (n = 16) | Fear (n = 16) | Disgust (n = 16) | No Expression(n = 8) |
| Pitch cues | ||||||
| F0SD (Hz, log values) | 1.78 (0.27) | 1.45 (0.17) | 1.71 (0.18) | 1.38 (0.29) | 1.53 (0.20) | 1.29 (0.22) |
| F0M (Hz, log values) | 2.42 (0.13) | 2.33 (0.10) | 2.37 (0.13) | 2.33 (0.15) | 2.26 (0.11) | 2.19 (0.11) |

| VoiceintSD (dB) | 7.92 (1.86) | 7.77 (2.25) | 9.00 (1.82) | 7.82 (3.04) | 7.97 (1.89) | 6.99 (0.76) |

Note: Bolded values reflect properties that are different for indicated emotion vs mean of all remaining emotions. Cues with at least one such significant difference were used in a second stage of analysis that examined contributions of specific acoustic properties to between-group performance.
