ChangeLog

Version numbers follow semantic versioning

not yet released

  • bugfixes

    • Fixed a bug when trying to restore punctuation on an empty text (see issue #54).

    • Fixed installation from source (bug introduced in 2.2.1, see issue #52).

phonemizer-2.2.1

  • improvements

    From Python import the phonemize function using from phonemizer import phonemize instead of from phonemizer.phonemize import phonemize. The second import is still available for compatibility.

  • bugfixes

    • Fixed a minor bug in utils.chunks.

    • Fixed warnings on language switching for espeak backend when using parallel jobs (see issue #50).

    • Save file in utf-8 explicitly for Windows compat (see issue #43).

    • Fixed build and tests in Dockerfile (see issue #45).

phonemizer-2.2

  • new features

    • New option --list-languages to list the available languages for a given backend from the command line.

    • The --sampa option of the espeak backend has been replaced by a new backend espeak-mbrola.

      • The former --sampa option (introduced in phonemizer-2.0) outputs phones that are not standard SAMPA but are adapted to the espeak TTS front-end.

      • On the other hand the espeak-mbrola backend allows espeak to output phones in standard SAMPA (adapted to the mbrola TTS front-end). This backend requires mbrola to be installed, as well as additional mbrola voices to support needed languages. This backend does not support word separation nor punctuation preservation.

  • bugfixes

    • Fixed issues with punctuation processing on some corner cases, see issues #39 and #40.

    • Improvments and updates in the documentation (Readme, phonemize --help and Python code).

    • Fixed a test when using espeak>=1.50.

    • Empty lines are correctly ignored when reading text from a file.

phonemizer-2.1

  • new features

    • Possibility to preserve the punctuation (ignored and silently removed by default) in the phonemized output with the new option --preserve-punctuation from command line (or the equivalent preserve-punctuation from Python API). With the punctuation-marks option, one can overload the default marls considered as punctuation.

    • It is now possible to specify the path to a custom espeak or festival executable (for instance to use a local installation or to test different versions). Either specify the PHONEMIZER_ESPEAK_PATH environment variable, the --espeak-path option from command line or use the EspeakBackend.set_espeak_path method from the Python API. Similarly for festival use PHONEMIZER_FESTIVAL_PATH, --festival-path or FestivalBackend.set_festival_path.

    • The --sampa option is now available for espeak (was available only for espeak-ng).

    • When using espeak with SAMPA output, some SAMPA phones are corrected to correspond to the normalized SAMPA alphabet (espeak seems not to respect it). The corrections are language specific. A correction file must be placed in phonemizer/share/espeak. This have been implemented only for French by now.

  • bugfixes

    • parses correctly the version of espeak-ng even for dev versions (e.g. 1.51-dev).

    • fixed an issue with espeak backend, where multiple phone separators can be present at the end of a word, see #31.

    • added an additional stress symbol - for espeak.

phonemizer-2.0.1

  • bugfixes

    • keep-flags was not the default argument for language_switch in the class EspeakBackend.

    • fixed an issue with punctuation processing in the espeak backend, see #26

  • improvements

    • log a warning if using python2.

phonemizer-2.0

  • incompatible change

    Starting with phonemizer-2.0 only python3 is supported. Compatibility with python2 is no more ensured nor tested. https://pythonclock.org.

  • bugfixes

    • new --language-switch option to use with espeak backend to deals with language switching on phonemized output. In previous version there was a bug in detection of the language switching flags (sometimes removed, sometimes not). Now you can choose to keep the flags, to remove them, or to delete the whole utterance.

    • bugfix in a test with espeak>=1.49.3.

    • bugfix using NamedTemporaryFile on windows, see #21.

    • bugfix when calling festival or espeak subprocesses on Windows, see #17.

    • bugfix in detecting recent versions of espeak-ng, see #18.

    • bugfix when using utf8 input on espeak backend (python2), see #19.

  • new features and improvements

    • new --sampa option to output phonemes in SAMPA alphabet instead of IPA, available for espeak-ng only.

    • new --with-stress option to use with espeak backend to not remove the stresses on phonemized output. For instance:

      $ echo "hello world" | phonemize
həloʊ wɜːld
$ echo "hello world" | phonemize --with-stress
həlˈoʊ wˈɜːld

    • improved logging: by default only warnings are displayed, use the new --quiet option to inhibate all log messages or --verbose to see all of them. Log messages now display level name (debug/info/warning).

    • improved code organization:

      • backends are now implemented in the backend submodule as separated source files.

      • improved version string (displays uninstalled backends, moved outside of main for use from Python).

      • improved logger implemented in its own module so as a call to phonemizer from CLI or API yields the same log messages.

phonemizer-1.0

  • incompabile changes

    The following changes break the compatibility with previous versions of phonemizer (0.X.Y):

    • command-line phonemize program: new --backend <espeak|festival|segments> option, default language is now espeak en-us (was festival en-us),

    • it is now illegal to have the same separator at different levels (for instance a space for both word and phone),

    • from Python, must import the phonemize function as from phonemizer.phonemize import phonemize, was from phonemizer import phonemize.

  • New backend segments for phonemization based on grapheme-to-phoneme mappings.

  • Major refactoring of the backends implementation and separators (as Python classes).

  • Input to phonemizer now supports utf8.

  • Better handling of errors (display of a meaningful message).

  • Fixed a bug in fetching espeak version on macos, see #14.

phonemizer-0.3.3

  • Fix a bug introduced in phonemizer-0.3.2 (apostrophes in festival backend). See #12.

phonemizer-0.3.2

  • Continuous integration with tracis-ci.

  • Support for docker.

  • Better support for different versions of espeak/festival.

  • Minor bugfixes and improved tests.

phonemizer-0.3.1

  • New espeak or espeak-ng backend with more than 100 languages.

  • Support for Python 2.7 and 3.5.

  • Integration with zenodo for citation.

  • Various bugfixes and minor improvments.

phonemizer-0.2

  • First public release.

  • Support for festival backend, American English only.
