Prosodic Cues for DA Recognition: It has also been noted that prosodic knowledge plays a major role in DA identification for certain DA types<cite> Stolcke et al., 2000)</cite> . The main reason is that the acoustic signal of the same utterance can be very different in a different DA class. This indicates that if one wants to classify DA classes only from the text, the context must be an important aspect to consider: simply classifying single utterances might not be enough, but considering the preceding utterances as a context is important.
