3.2. Architecture of the proposed system
The proposed system is composed of an FST script
generator and a mobile map annotation system.
3.2.1. FST script generator:. The FST script generator
generates FST scripts for voice navigation from guide annotations,
as illustrated in Fig. 3. This system consists of a
guide annotation series generation function, an FST script
generation function, FST templates, and a guide annotation
database (containing guide annotations added by users).
It generates FST scripts for voice navigation from both
navigation route and the guide annotation database. The
guide annotation series generation function creates guide
annotation series, of the navigation route by referencing
both the route and the database. The FST script generation
function generates FST scripts for navigation using guide
annotation series, and FST templates.
