Table 1.

Example of the order of experimental tasks for the first day of the larger project. Each grouping of data-collecting trials (acoustic and aerodynamic) was preceded by 30-s practice trials.

Day 1
Four 3-min monologues
Four 3-min readings
Control reading: 30-s aerodynamic trials, 75-s acoustic trials
Condition X: 75-s acoustic trials, 30-s aerodynamic trials
Rest period (2-min monologues)
Reading-1.0 s: 30-s aerodynamic trials, 75-s acoustic trials
Rest period (2-min monologues)
Condition X: 75-s acoustic trials, 30-s aerodynamic trials
Rest period (2-min monologues)
Condition X: 30-s aerodynamic trials, 75-s acoustic trials
Rest period (2-min monologues)
Condition X: 75-s acoustic trials, 30-s aerodynamic trials

Note. The order of the aerodynamic and acoustic trials was reversed in each subsequent condition to conserve time by not needing to remove and replace equipment (microphone and accelerometer) as frequently. Condition X refers to the conditions not analyzed for the present study.
