pVoice is a communications application for severely disabled people. Keep this in mind while you work with pVoice. Often things work different than you expect, but most of the things that are "different" are designed to make it easier for the people who are supposed to work with it.
The basic idea behind pVoice is that someone who can't speak, uses pVoice to create phrases.
To create phrases, someone else must have filled the pVoice database with data: the vocabulary.
Therefore pVoice has two modes of operation: user mode and edit mode. In user mode the user
is able to select symbols and/or letters on the screen, thereby forming phrases, and let them be
pronounced using an installed speech synthesizer.
In edit mode, someone capable of using a mouse and a keyboard can make additions and modifications
to the vocabulary.
Vocabularies can be organized into hierarchical themes. For example, you could have a theme called
"Animals", in which of course you could put all possible animals, but you could also use a more
structured approach and make several subthemes in the "Animals" theme, like "Mammals",
"Birds", "Pets", etcetera. This is for the vocabulary editor to decide.
