A text-to-speech engine typically provides an assortment of text-to-speech modes that can be used to play speech in different voices. A voice text site uses a single text-to-speech mode, represented internally by a low-level engine object.
The text-to-speech mode for a site is saved between uses of the site, even if the user shuts down the computer in the meantime.
In Auto PC, there is usually only one TTS mode.
