espeak 1.48.04  06.04.2014

Corrections to languages en, nl, ta (rules, list, and dict files).
No other changes from version 1.48.03. No change to program, phoneme
data, espeakedit, or other languages.


espeak 1.48.03  04.04.2014

Fix bug, use of the command-line  "espeakedit --compile" produced phoneme data
in which vowels started at full amplitude instead of gradual increase.

Fix bug:  SSML <break time=""> with values greater than 23 seconds were ignored
due to arithmetic overflow.

Phoneme definition files:
Added new function:  ChangeNextPhoneme().

Language changes include: da, en, fa, gu, hu, it, nl, pt, ta

Started new language: eu (Basque).

*_rules files:
Allow $p_alt1, $p_alt2, etc in pre-conditions.  The rule matches if the
characters before the current point in the word occur as an entry in the
*_list file with the corresponding $alt attibute.

Added condition $list.  This is similar to $p_alt etc, but examines
all words in the *_list file which don't have the $only attribute.



espeak 1.48.01  02.02.2014

*_rules files:
Added rule attribute $noprefix.  The rule is not used if a prefix has been removed from the word.

Added attribute 'dictdialect' to specify en-us voice for words marked with _^_EN.

Superscripts and subscripts are spoken as single letters and numbers during normal speech, and with "superscript" and "subscript" also spoken when spelling.
