In-Depth Information
Individual computers are used for speech input‚ sound output‚ three video
channels‚ and vehicle related data. In Table 1-3‚ we list the recording
characteristics of 12-speech and 3-video channels‚ five analog control signals
from the vehicle representing the driving behavior of drivers and the location
information from the DGPS unit built into the DCV. These multi-dimensional
data are recorded synchronously‚ and hence‚ they can be synchronously
analyzed.

Multi-mode Dialogue Data Collection
The primary objective of the dialogue speech collection is to record three
different modes of dialogue mentioned earlier. It is important to note that the
task domain is the information retrieval task for all three modes. The
descriptions of these dialogue modes are:
Dialogue with human navigator (HUM):
Navigators are trained in

However‚ in order to avoid a dialogue divergence‚ some restriction is
put on the way he/she speaks.
