Through the table, you can query the position coordinates of the place from the table.

5.3 The Preparation of Viavoice System

After we install the Viavoice software, we need to set the environment, volume and
speech.
Through the voice input device, Viavoice can detect the noise of current environ-
ment, then recognize the speech. From the experiment, the Viavoice has high recogni-
zation rate in quiet environment.
Viavoice also can carry out the training. The users can read paragraphs provided by
system, so the system can record and adapt to the users' accent which is helpful to
improve the speech recognition rate [7] [8].

Fig. 3. The training of accent

After carry out the settings and training, we need to set the system as "dictation to
the current application" which will provide the recognition text for plotting system,
then the plotting system can deal with the text and realize automatic plotting.

6 System Implementation

6.1 The Development of MGIS

The underlying platform of the intelligent plotting is a certain type of military geo-
graphic information system, the development platform is based on VC++. The mili-
tary geographic information system already contains map display, map operation
(roam, zoom, etc), terrain analysis (distance, area), plotting, military symbol library
and other related functions, and provides the military plotting, military symbol edit,
military symbol delete and other development functions, user can achieve the required
development.
