So we know they are just tables, get protected from overflows, and get shared between processes

speechPlayer_terminate was never called without calling
speechPlayer_initialize right after, so there would always be a FrameManager
laying behind.

Going through files in src/libespeak-ng/, include-what-you-use removed a
few unnecessary includes and included explanations on why a certain
header should be included. This makes tracking globals and dependencies easier.

Running the codebase through IWYU should be repeated after each major
code restIncludes to standard c library weren't checked to avoid
breaking builds with other platforms.

See https://github.com/include-what-you-use/include-what-you-use

Unsigned char *out_start is a global only used in speech.c.

SetSynth_Klatt() was using wvoice in two ways:
1) global wvoice was used directly
2) global wvoice was also passed in Wavegen_Klatt() as an argument "v"

Now the code only uses the function argument wvoice

Contributes to #68.

Contributes to #68.

Wavegen_Klatt2() only had one if-statement and then called
Wavegen_Klatt(). Wavegen_Klatt() was never called directly.

Indeed, the out_ptr >= out_end test is not enough: it only checks that
one byte can fit the buffer, while klatt and wavegen produce two bytes.

This makes the codebase more consistent. Including speech.h is not necessary anymore in some files. Includes have been removed.

Moved include/espeak/speak_lib.h to include/espeak-ng/speak_lib.h and
created a symlink from the original location.

This reverts commits 0cc0300328 to
38d15f8f90.

The 0cc03003 commit breaks MBROLA voice support. As such, there
may be other breakages in those commits.

This commit has been reported to cause distortions in phoneme
pitches and speeds.

Also use size_t instead of int in some places
where it make sense

This moves the libespeak source (*.cpp) files to src/libespeak-ng
and renames the C files (libespeak, espeak, speak) so they have
a .c file extension.

StdAfx.h is only needed for Microsoft Visual Studio C++ projects
that specify the "use pre-compiled headers" setting.

Fix: Flush stderr() after espeak_CompileDictionary().
Fix: parallel formant parameters for Klatt synthesizer.
Changes for Malayalam numbers.
Language changes: en-us,  nl, pt, sl, ta, ur.

Fixed bug where SSML voice change didn't remember an initially specified Klatt variant.

Removed some unused variables and redundant initializations.

Patch to fix a spike from Klatt function setzeroabc()


git-svn-id: https://espeak.svn.sourceforge.net/svnroot/espeak/trunk@275 d46cf337-b52f-0410-862d-fd96e6ae7743

If setzeroabc is passed f == 0, rp->a will be set to 0 and when
the coefficients get inverted (a'=1/a, b'=b/a, c'=c/a) then a',
b' and c' get set to INF. This results in an audible sound spike
when these resonators get used.

Found when investigating an issue in klatt with example1.par when
using the cascade synthesis mode.

Bug: https://github.com/rhdunn/klatt/issues/1.

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.

espeakedit --compile  also compiles the intonation data

Added feature to produce phonemes as International Phonetic Alphabet.
phoneme definitions: Added "ipa" instruction to specify IPA phoneme name.

When spelling as individual characters, calculate the stress position for each character name.
