Real-time Handling of Fragmented Utterances

• this paper, we discuss an adaptive method of handling fragmented user utterances to a speech-based multimodal dialogue system. Inserted silent pauses between fragments present the following problem: Does the current silence indicate that the user has completed her utterance, or is the silence just a pause between two fragments, so that the system should wait for more input? Our system incrementally classifies user utterances as either closing (more input is unlikely to come) or non-closing (more input is likely to come), partly depending on the current dialogue state. Utterances that are categorized as non-closing allow the dialogue system to await additional spoken or graphical input before responding
