Proceedings Article
Prosody-based automatic detection of annoyance and frustration in human-computer dialog.
TL;DR: Results show that a prosodic model can predict whether an utterance is neutral ve sus “annoyed or frustrated” with an accuracy on par with that of human interlabeler agreement.
ReportDOI
The ICSI Meeting Recorder Dialog Act (MRDA) Corpus
TL;DR: A new corpus of over 180,000 hand- annotated dialog act tags and accompanying adjacency pair annotations for roughly 72 hours of speech from 75 naturally-occurring meetings is described.
Proceedings ArticleDOI
Automatic dialog act segmentation and classification in multiparty meetings
TL;DR: It is found that a very simple prosodic model aids performance over lexical information alone, especially for segmentation, in the two related tasks of dialog act segmentation and DA classification for speech from the ICSI Meeting Corpus.

TL;DR: A representative sample of results shows that combining multiple knowledge sources (words, prosody, syntactic information) is helpful, that prosody is more helpful for news speech than for conversational speech, that word errors significantly impact performance, and that discriminative models generally provide benefit over maximum likelihood models.
