## espeak-ng

The espeak-ng project is a fork of the espeak project.

### 1.49.3 - (In Development)

*  Add a `--disable-rpath` option to prevent libtool hardcoding rpaths in the executable.
*  Renamed the `hy-arevmda` language to `hyw`, following the 2018-03-30 change to the
   BCP 47 language subtag registry making the newly registered `hyw` language code the
   preferred value for `hy-arevmda`. This change keeps support for detecting the
   `hy-arevela` and `hy-arevmda` language tags.
*  Add more tests to check the various parts of espeak-ng.
*  Various changes to clean up the codebase.
*  Fix various compiler warnings (`-Winitialized`, `-Wmissing-prototypes`, `-Wreturn-type`,
   and `-Wunused`).

security:

*  Fix several crashes in the emoji support.
*  Fix several static analysis issues detected by Coverity Scan.
*  Fix several static analysis issues detected by Microsoft Visual C++ `/analyze`.
*  `oss-fuzz` support for the SSML logic.
*  Fix running `make check` with `-fsanitize=address` (LLVM AddressSanitizer).

documentation:

*  document the Kirshenbaum phoneme transcription scheme (used as the basis of espeak phonemes).
*  document the X-SAMPA phoneme transcription scheme.
