What’s the procedure?
Compute the pitch curve as a function of phonological inputs and prosodic strength.
Sequence of tones (phonology)
Prosodic strengths
Predicted F0
Data
Nonlinear least-squares fitting algorithm
Middle red box is what we talked about so far.    Prosodic strengths are the output.  You go around the loop, adjusting the model’s parameters until it agrees well with the data.
