Realization of information structure by means of intonation

Experimental implementation of information structure realisation through intonation with Mary and Festival TTS in GoDIS:

We developed an implementation in the GoDIS (questions under discussion) system, which enables to experiment with the realization of information structure by means of intonation, using two off-the-shelf text-to-speech (TTS) synthesis systems, namely the Festival TTS for English and the Mary TTS for German and English. These TTS systems support high-level control of intonation by using either the SABLE standard or a ToBI-based intonation markup.

We defined experimental mappings from information structure categories to intonation annotation, and ran a small-scale evaluation of the synthesized output in different versions. The evaluation results indicate that controlling the output intonation by determining intonation according to information structure with respect to the information state leads to improving the appropriateness of the system output.
