     Dialog speech communicates a lot of implicit nonverbal
information as well as verbal information.  We look into some examples
of dialog speech from the point of acoustic analysis, and present
preliminary results of the machine readable form of the analysis data.

     First, we validated the study of the dialog speech along the
development of speech processing technologies as well as related
sciences such as the new trends of linguistic study and the behavior
science.  Secondly, we emphasized the necessity of a further extended
new framework for research of speech technology.  Then, we considered
concrete method incorporating nonverbal information into the dialog
speech.  The concepts of the nonverbal speech information that follows
the original definition by Trager are inherited into the field of
sociolinguistics and behavior science as the concept of the
paralanguage and recently formalized as the "a guideline to Text
Encoding and Interchange (TEI)".  We adopted this formalization as a
new framework of dialog speech encoding.  Finally, we have shown an
example of labeling of dialog speech with the method incorporating the
TEI as the description of the nonverbal aspects of the dialog speech.
We are going to develop this approach toward the applications of
speech recognition, linguistic analysis and dialog analysis.
