eSpeak NG is a compact open source software text-to-speech synthesizer for Linux, Windows, Android and other operating systems

eSpeak NG Text-to-Speech


The eSpeak NG is a compact open source software text-to-speech synthesizer for Linux, Windows, Android and other operating systems. It supports more than 100 languages and accents. It is based on the eSpeak engine created by Jonathan Duddington.

eSpeak NG uses a "formant synthesis" method. This allows many languages to be provided in a small size. The speech is clear, and can be used at high speeds, but is not as natural or smooth as larger synthesizers which are based on human speech recordings. It also supports Klatt formant synthesis, and the ability to use MBROLA as backend speech synthesizer.

eSpeak NG is available as:

  • A command line program (Linux and Windows) to speak text from a file or from stdin.
  • A shared library version for use by other programs. (On Windows this is a DLL).
  • A SAPI5 version for Windows, so it can be used with screen-readers and other programs that support the Windows SAPI5 interface.
  • eSpeak NG has been ported to other platforms, including Solaris and Mac OSX.

Features

  • Includes different Voices, whose characteristics can be altered.
  • Can produce speech output as a WAV file.
  • SSML (Speech Synthesis Markup Language) is supported (not complete), and also HTML.
  • Compact size. The program and its data, including many languages, totals about few Mbytes.
  • Can be used as a front-end to MBROLA diphone voices. eSpeak NG converts text to phonemes with pitch and length information.
  • Can translate text into phoneme codes, so it could be adapted as a front end for another speech synthesis engine.
  • Potential for other languages. Several are included in varying stages of progress. Help from native speakers for these or other languages is welcome.
  • Written in C.

See the CHANGELOG for a description of the changes in the various releases and with the eSpeak NG project.

The following platforms are supported:

Platform Minimum Version Status
Linux Travis continuous integration builds on Linux
BSD
Android 4.0
Windows Windows 8
Mac

eSpeak Compatibility

The espeak-ng binaries use the same command-line options as espeak, with several additions to provide new functionality from espeak-ng such as specifying the output audio device name to use. The build creates symlinks of espeak to espeak-ng, and speak to speak-ng.

The espeak speak_lib.h include file is located in espeak-ng/speak_lib.h with an optional symlink in espeak/speak_lib.h. This file contains the espeak 1.48.15 API, with a change to the ESPEAK_API macro to fix building on Windows and some minor changes to the documentation comments. This C API is API and ABI compatible with espeak.

The espeak-data data has been moved to espeak-ng-data to avoid conflicts with espeak. There have been various changes to the voice, dictionary and phoneme files that make them incompatible with espeak.

The espeak-ng project does not include the espeakedit program. It has moved the logic to build the dictionary, phoneme and intonation binary files into the libespeak-ng.so file that is accessible from the espeak-ng command line and C API.

History

The program was originally known as speak and originally written for Acorn/RISC_OS computers starting in 1995 by Jonathan Duddington. This was enhanced and re-written in 2007 as eSpeak, including a relaxation of the original memory and processing power constraints, and with support for additional languages.

In 2010, Reece H. Dunn started maintaining a version of eSpeak on GitHub that was designed to make it easier to build eSpeak on POSIX systems, porting the build system to autotools in 2012. In late 2015, this project was officially forked to a new eSpeak NG project. The new eSpeak NG project is a significant departure from the eSpeak project, with the intention of cleaning up the existing codebase, adding new features, and adding to and improving the supported languages.

The historical branch contains the available older releases of the original eSpeak that are not contained in the subversion repository.

1.24.02 is the first version of eSpeak to appear in the subversion repository, but releases from 1.05 to 1.24 are available at http://sourceforge.net/projects/espeak/files/espeak/.

These early releases have been checked into the historical branch, with the 1.24.02 release as the last entry. This makes it possible to use the replace functionality of git to see the earlier history:

git replace 8d59235f 63c1c019

NOTE: The source releases contain the big_endian, espeak-edit, praat-mod, riskos, windows_dll and windows_sapi folders. These do not appear in the source repository until later releases, so have been excluded from the historical commits to align them better with the 1.24.02 source commit.

    Strangely, I get similar bad results on older commits (for which I'm sure it was working before under MacOS Mojave). Does anyone have a clue on how to investigate this? Could it be related to the fact that 64-bits applications and compilation have been ditched from MacOS (is espeak-ng 64-bits bullet proof) ?

  • problems with russian language

    problems with russian language

    hello.

    with recent changes with russian language pronunciation of several words were changed. for example word "общение" letter щ sch is incorrectly pronounced.

    letters when typing is also pronounced incorrectly, they are short for example с б в ж к letter л is very soft.

    i have a question why person who has no knowledge of this language such as @valdisvi is changing so serious things? if he had, these mistakes which makes synthesizer usable in russian language never be existed.

    please revert changes or fix them.

    thanks.

  • New release of espeak

    As per: #792

    Over at nvaccess/nvda we have started our 2021.1 release process by updating the version of espeak-ng included. We selected the latest espeak-ng commit (at the time) and would love it if an espeak-ng release process could be started that we could use for the final release.

    We have updated to espeak-ng commit 82d5b7b04488412845101851f36da6953cac4378F The NVDA 2021.1 release will be made in the first quarter of 2021.

  • add SpeechPlayer as Klatt6

    add SpeechPlayer as Klatt6

    I managed to add NV SpeechPlayer as Klatt 6. I also was able to remove the Windows specific code from speechPlayer, and the library still works. I am using it with NVDA as I write this. I updated the visual studio project with the new source files. To update the other projects, you should add the following files:

    • libespeak-ng/sPlayer.c
    • speechPlayer/frame.cpp
    • speechPlayer/speechPlayer.cpp
    • speechPlayer/speechWaveGenerator.cpp I also added a compiler define for including SpeechPlayer, INCLUDE_SPEECHPLAYER.
  • Cmn voice not correctly translated

    Cmn voice not correctly translated

    @jaacoppi

    This is a following issue of #1044.

    I apologize for my not careful test. I find issues after @cary-rowen tell me that there are still problems with Chinese Mandarin voice.

    Here is the current voice output:

    $ espeak-ng -x -vcmn '此电脑 means this computer'
    c'i3_| di11'a4n_| na11'o3_| (en)mi:11nz_| DI11s_| [email protected]:11t311(cmn)_|
    

    And following output from older version is much better than current situation:

    tsh'i[21_| t'iE51n_| n'Au21_| (en)mi:44nz_| DI11s_| [email protected]:11t311(cmn)_|
    

    Maybe this is why you had comment: https://github.com/espeak-ng/espeak-ng/issues/1044#issuecomment-993829386

    Here is the revert code: cmn_revert.patch.txt

    In fact, it's a temporary solution of #1163 .

    I will try to compare the rules of Cantonese and Mandarin to find whether there are clues to make both Mandarin and English read correctly.

  • (Turkish) vocalization of words with double letters saying of one letters

    (Turkish) vocalization of words with double letters saying of one letters

    Hello,

    there has been some shortcomings in Espeak's Turkish voice synthesis for a long time.

    The same letter can be found twice in some words in Turkish. (For example, [tr}tutturmak, elli)

    Espeak say these words in a single letter. (tuturmak, eli)

    I don't have enough C knowledge to develop Espeak. So I can only give information.

    Small information

    This issue does not exist in version eSpeak-2016.1. I don't know Espeak's versioning system. I'm not sure of the values ​​I've given above, and if you have any questions, I'll try to help. Starting from the old version, we can find out where the problem is from the changing Turkish files.

    I apologize for inadequate English. The topic is language, I would appreciate it if you simply write your answers. I don't understand complex sentences.

  • questions about mandarin data packet

    questions about mandarin data packet

    I install espeak for several times, I use the --compile=cmn or zh in dictsource or dictsource/extra , it said Full dictionary is not installed for 'zh' Error processing file 'zh_rules': No such file or directory. but there is a file called cmn_rules and cmn_list in dictsource How can I install mandarin?

    And the other question, I try to input chinese and get mandarin phoneme like [input: 你好] output[ n i 3 h ao 3]. Is the espeak software can output mandarin phoneme or only IPA? Thanks.

    Also I downloaded the version 1.49.1 of espeak-ng clearly it was stated this

    new languages:
    
    ar (Arabic) -- Taha Zerrouki
    jp (Japanese) -- Reece Dunn (NOTE: Hiragana and Karakana only.)
    

    There is japanese but when I tried it, there's NOTHING may I ask... do you really have it?

    Have I installed an old version? or am I just not getting something? What is happening? Why is there Japanese on the .md file where there is NOTHING in mine? If so where is the lastest version link download? I need to have this, this is a cool software! Thank you!

  • Android release doesn't work

    Android release doesn't work

    I recently installed the F-Droid release of eSpeak, version 1.51-dev.20. However it was unusable because of these issues:

    • No voices are installed
    • Import eSpeak dictionary setting doesn't work
    • eSpeak is selectable in Android Text-to-speech output, but tapping it, will not select it, even though the "ripple" effect plays.

    Any idea what I can do to solve this? Screenshot_20210629-210855_1

  • 1.51 release tarball is missing files

    1.51 release tarball is missing files

    I tried to compile espeak-ng 1.51 on macOS using the release tarball. It failed because the release tarball is missing the header files:

    src/libespeak-ng/compiledict.c:36:10: fatal error: 'compiledict.h' file not found
    #include "compiledict.h"
             ^~~~~~~~~~~~~~~
    src/libespeak-ng/compiledata.c:38:10: fatal error: 'dictionary.h' file not found
    #include "dictionary.h"               // for strncpy0
             ^~~~~~~~~~~~~~
    1 error generated.
    1 error generated.
    make: *** [src/libespeak-ng/la-compiledict.lo] Error 1
    make: *** Waiting for unfinished jobs....
    make: *** [src/libespeak-ng/la-compiledata.lo] Error 1
    

    The 1.51 release tarball is only 1 MiB in size, vs. over 20 MiB for the 1.50 release tarball, so I would guess a lot more than headers is missing from it.
