eSpeak: speech synthesis Code

[1.47.08]
Add API function: espeak_TextToPhonemes().

[1.47.07a]
Use internal data for iswalpha(), towlower() for characters up to U+024F.
Language changes: es, nl, pt, tr, vi.

[1.46.53]
espeakedit, show path to phsource when compiling.

[1.46.39]
Fixes to speaking characters from foreign alphabets.
Allow $textmode and $text to translate between words in different alphabets.

[1.46.36]
espeakedit: Prosody window now shows the FMT() or WAV() filename
and the standard length of the selected phoneme.

Added the ability to produce speech at different sample rates.
To use rates other than the default 22050Hz, the phoneme data must
be recompiled. This needs the "sox" program to be available.
(sox.sourceforge.net).

espeakedit: Added menu option to compile the phoneme data at a
specified sample rate (rather than the default 22050Hz).

phondata: Includes the value of the sample rate at which the data was compiled.

Language changes: pt.

espeakedit: Change from wxMDI to wxNotebook for prosody and vowel pages.
espeakedit: (linux) change to wxWidgets 2.8.

New keyword "prevoice", always add murmer before a voiced stop, not only after a vowel.
Fixed bug in nextVowel() condition.

Command line options.
On Windows, -- means don't treat following arguments as options.
--help output now should the espeak-data path.

Tools->Lexicon. Redesign Lexicon processing for Russian and Bulgarian.

Numbers. Fixes for Hungarian ordinal numbers.

Fixed bug where double .. was ignored.

Fixed bug in reporting word event lengths in callbacks.
Fixed bug in reporting marker event positions in callbacks, when non-ascii text.

SSML.

Fix bugs in SSML "prosody rate".

Speed.
Only use Sonic speedups greater than x2.
Use custom eSpeak speed settings when Sonic speedup is used.

Mbrola. Look for Mbrola voice also at /usr/share/mbrola/xx/xx

espeakedit. Try "aplay" and then "play" to play sound.

Languages:
Kannada (kn) now in official release.

lang=hu, fixes for ordinal numbers.
Speed-up, add files sonic.cpp, sonic.h

[1.43.63]
Phoneme definitions. Add "equivalents" table to translate phonemes from a foreign language (eg. English) into the equivalant phonemes of this language. This is used when *_rules and *_list files indicate that a word uses pronunciation rules from a different language.

Unpronouncable words can be recognised by rules in *_rule files. This feature is now used for en, de, es.

Lang=ta, hi. Letter-names for combining vowel characters are distinguished from stand-alone vowel characters by a preceding beep.

[1.43.57]
Indicate language changes in IPA phoneme output.

Phoneme definitions FMT(), second parameter is amplitude percentage.

Phoneme definitions CALL(), If phoneme type is not defined, copy the static attributes from the called phoneme.

Unpronouncable word check: stop when an apostrophe is reached.
