the second day was tourist attraction information. This suggests that speakers
are most interested in traffic information before starting a trip, and tourist
attraction information before leaving the hotel, which coincides with the
intuition of most drivers. It is also worthwhile to note that the frequency of
the shopping task increased from 2% to 9% on the second day, since many
speakers were interested in purchasing souvenirs on their way home on the
last day of their trip. Although the spoken dialog corpus was collected in a
studio, these observations support the idea that realistic travel experiences
were reflected in the experimental tasks, thus validating the task setting and
the instructions described in Section 3.
Possibly, the general tasks of type 'Introduction' are part of the
fundamental nature of human-human dialog. The ratio of 'Introduction'
utterances as shown in Figure 3-11 will most likely decline when human-
machine dialog is implemented.
