From Tale to Speech: Ontology-based Emotion and Dialogue Annotation of Fairy Tales with a TTS Output

In this demo and poster paper, we describe the concept and implementation of an ontology-based storyteller for fairy tales. Its main functions are (i) annotating the tales by extracting timeline information, characters and dialogues with corresponding emotions expressed in the utterances, (ii) populating an existing ontology for fairy tales with the previously extracted information and (iii) using this ontology to generate a spoken version of the tales. Common natural language processing technologies and resources, such as part-of-speech tagging, chunking and semantic networks have been successfully used for the implementation of the three tasks mentioned just above, including the integration of an open source text-to-speech system. The code of the system is publicly available.
