A PCFG for prosodic structure: experiments on German
Michaela Atterer, Sabine Schulte im Walde · 2004
In this paper we investigate the usefulness of a probabilistic context-free grammar (PCFG) for assigning prosodic structure to unlabelled text.We develop and train a grammar for experiments on German, utilising prosodic non-terminal categories such as phi-phrases.The PCFG is evaluated on test data and by human blind labelling.The statistical prosodic rules can be used in a text-to-speech synthesis system for determining the location of prosodic breaks.
