# ProPer analyses (IV): *Synchrony*, *∆F0*/*DeltaF0*, *Mass* and *Speech-rate*

Quantifying continuous prosody with periodic energy and F0 data to quantify prosodic strength (*Mass*), to describe pitch contours (using *Synchrony* within intervals and *∆F0*/*DeltaF0* between intervals) and to calculate local *Speech-rate*.

# Calculate

The following are a set of functions that are based on the boundary detection above (*boundary_detection* chunk) and computations within and across resulting intervals (in the following *run_fun* chunk). We measure the area under the periodic energy curve (*mass*), and the center of mass of the periodic energy curve (*CoM*). We calculate local *speech-rate* in terms of the temporal distance between consecutive CoMs, and we calcualte *∆F0*/*DeltaF0* as the F0 distance between consecutive CoMs. We also locate the center of gravity of F0 (*CoG*), and we calcualte *synchrony* as the distance between centers (CoG - CoM).
