11. Emacs interface
One easy method of using Festival is via an Emacs interface that allows selection of text regions to be sent to Festival
for rendering as speech.
`festival.el' offers a new minor mode which offers an extra menu (in emacs-19 and 20) with options for
saying a selected region, or a whole buffer, as well as various general control functions. To use this you must install
`festival.el' in a directory where Emacs can find it, then add to your `.emacs' in your home directory the
following lines.
(autoload 'say-minor-mode "festival" "Menu for using Festival." t)
(say-minor-mode t)
Successive calls to say-minor-mode will toggle the minor mode, switching the `say' menu on and off.
Note that the optional voice selection offered by the language sub-menu is not sensitive to actual voices supported by
the your Festival installation. Hand customization is require in the `festival.el' file. Thus some voices may
appear in your menu that your Festival doesn't support and some voices may be supported by your Festival that do
not appear in the menu.
When the Emacs Lisp function festival-say-buffer or the menu equivalent is used the Emacs major mode is
passed to Festival as the text mode.

12. Phonesets
The notion of phonesets is important to a number of different subsystems within Festival. Festival supports multiple
phonesets simultaneously and allows mapping between sets when necessary. The lexicons, letter to sound rules,
waveform synthesizers, etc. all require the definition of a phoneset before they will operate.
A phoneset is a set of symbols which may be further defined in terms of features, such as vowel/consonant, place of
articulation for consonants, type of vowel etc. The set of features and their values must be defined with the phoneset.
The definition is used to ensure compatibility between sub-systems as well as allowing groups of phones in various
prediction systems (e.g. duration)
A phoneset definition has the form
(defPhoneSet
NAME
FEATUREDEFS
PHONEDEFS )
The NAME is any unique symbol used e.g. mrpa, darpa, etc. FEATUREDEFS is a list of definitions each
consisting of a feature name and its possible values. For example
