Abstract:
In this chapter‚ we will discuss the construction of the multi-layered in-car
spoken dialogue corpus and the preliminary result of the analysis. We have
developed the system specially built in a Data Collection Vehicle (DCV) which
supports synchronous recording of multi-channel audio data from 16
microphones that can be placed in flexible positions‚ multi-channel video data
from 3 cameras and the vehicle related data. Multimedia data has been collected
for three sessions of spoken dialogue with different types of navigator in about
60-minute drive by each of 800 subjects. We have defined the Layered Intention
Tag for the analysis of dialogue structure for each of speech unit. Then we have
marked the tag to all of the dialogues for over 35‚000 speech units. By using the
dialogue sequence viewer we have developed‚ we can analyze the basic
dialogue strategy of the human-navigator. We also report the preliminary
analysis of the relation between the intention and linguistic phenomenon.
