Abstract

It has been observed that for the Greek language, in Service- Oriented Dialog Systems targeted towards the broad public, verbs display particular features to be considered both in the System's Speech Recognition (ASR) and Speech Synthesis (or Speech Production) Module. Additionally, the function of verbs, both in respect to their role in the semantic content of the spoken utterance and in respect to their prosodic features in the spoken utterance, is observed to be directly linked to the step and the related Speech Act in the dialog structure. From a prosodic aspect, it is observed that, in spoken input, "Multitasking" verbs do not receive prosodic emphasis, whereas in spoken output, prosodic emphasis is given on words signalizing the User-System Relationship.
