General description
The Parametric All-Prosodic MBROLA PHO file generator requires two inputs:
Definitions and processing strategy
The input sentence is processed as follows:
pitchi = baseline + onset * slopei
That is, the pitch of phonemei, the phoneme at position i in the sentence, is defined as the baseline added to the product of the onset (initial pitch), and the declination. The declination is the slope raised to the power of i, the position of phoneme i in the sentence. If slope < 1, the declination falls asymptotically towards the baseline, but never quite reaches it.
Output
The output of the Parametrised All-Prosodic MBROLA PHO file generator is a PHO file with the following specifications:
