Objective: This research investigated the relative values of intensity when participants were given a target vocal effort level (VEL) and if transient mood impacted these values. Method: Twenty-seven participants completed three experimental blocks. 36 trials were completed in Block 1 consisting of rote speech tasks, reading tasks, and 3 unique map tasks all executed at the four targets VELs. Block 2 consisted of an additional 36 rote speech task trials with the addition of emotional stimuli. Finally, 12 additional automatic speech trials were executed in Block 3. Results: Results revealed vocal intensity was significantly distinct for all elicited VELs within a given experimental block and repeatable for each VEL when comparing the initial and final blocks of the experiment. Additionally, transient mood did not have a noticeable effect on the produced intensity levels. Conclusion: The current study provided insight and evidence to the significant association between vocal effort and intensity output.
