 Wordset - built-in set of SI commands (for instance in Figure 3 above, the Wordset 1 is selected)
 Grammar – custom set of SI commands (created with Quick T2SI Lite software).
Speech Recognition
The recognition function of the EasyVR works on a single group at a time, so that users need to group
together all the commands that they want to be able to use at the same time.
When EasyVR Commander connects to the module, it reads back all the user-defined commands and
groups, which are stored into the EasyVR module non-volatile memory.
You can add a new command by first selecting the group in which the command needs to be created and
then using the toolbar icons or the “Edit” menu.
A command should be given a label and then it should be trained twice with the user's voice: the user will
be guided throughout this process (see Figure 4) when the "Train Command" action is invoked.
Note: Only Latin characters and digits can be used for labels, as well as the underscore
character.

After clicking on “Phase 1” or “Phase 2” buttons, remember you have to start speaking only when you see
this little window:
If any error happens, command training will be cancelled. Errors may happen when the user’s voice is not
heard correctly, there is too much background noise or when the second word heard is too different from
the first one.
