``LANGUAGE''

The language-tag now works with german and english. Speakers of another language may easily be added.
Possible values

• for spanish are:
  • spanish
  • es
• for english are:
  • english
  • en
• for german are:
  • german
  • ge
  • de

whereas ``sable_init_func'', ``set_ttw_functions'' and ``restore_ttw_functions'' have to be adjusted for the spanish language.
Just a few things to be done to add other languages (see speaker-tag):

1. ``init-function'':
   1. another branch has to be added to the cond-statement equivalent to the ``german-branch''
   2. in ``sable_init_globals'', another branch has to be added to the cond-statement equivalent to the ``german-branch''
2. ``restore_ttw_functions'':
   1. another branch has to be added to the cond-statement equivalent to the ``german-branch''
3. ``set_ttw_functions'':
   1. another branch has to be added to the cond-statement equivalent to the ``german-branch''

How the language-tag works:

• opening of the language-tag:
  1. xxml_synth
  2. current language is pushed on the sable_language_stack
  3. set back token_to_words-function of current language (at the moment only distinguished between german and non-german) using ``restore_ttw_functions''
  4. selection of the new language
  5. set token_to_words on sable_token_to_words because this is overwritten in the setting of english voices
  6. set german_token_to_words on sable_token_to_words (after saving german_token_to_words in sable_previous_token_to_words) if language of chosen voice is german
     using ``set_ttw_functions''
     set english_token_to_words on sable_token_to_words (after saving english_token_to_words in sable_previous_token_to_words) if language of chosen voice is not german
     using ``set_ttw_functions''
  7. sable_setup_voice_params
• closing of the language-tag:
  1. xxml_synth
  2. set back token_to_words-function of current language (at the moment only distinguished between german and non-german) using ``restore_ttw_functions''
  3. pop last language from stack
  4. evaluate current speaker
  5. set token_to_words on sable_token_to_words because this is overwritten in the setting of english voices
  6. set german_token_to_words on sable_token_to_words (after saving german_token_to_words in sable_previous_token_to_words) if current language is german
     using ``set_ttw_functions''
     set english_token_to_words on sable_token_to_words (after saving english_token_to_words in sable_previous_token_to_words) if current language is not german
     using ``set_ttw_functions''
