The Read Text Extension lets an external program or web application read text from Writer, Calc, Draw, Impress, Web Writer or the system clipboard. If you use it to read text aloud, it can help you to edit your writing or to compare your document's text with a printed document. If you use it with a web application, you can translate your text to another language or check punctuation and grammar. It can help you to learn a new language or to find out how to say words you do not know.

To use it, highlight some text. If you are using the word processor or the HTML editor, you can highlight several selections by holding down the Control key. When you have highlighted some text, select Tools - Add-Ons - Read Selection or click the Read Selection button on the tool bar.

To read the system clipboard, select Tools → Add-Ons → Read clipboard.

If you can't read the screen easily, consider a system-wide accessibility solution for Apple OSX, Gnome, KDE or Microsoft Windows. If you have installed a system-wide accessibility solution, and it is activated, then you might not need this Add-On to read text aloud. You can use the Read Text Extension to read using a different language or voice, to save speech as an audio file, or send the text to a web application.

The add-on uses temporary files to send information to external programs. Depending on the security set up of your computer, other users or programs might be able to read the contents of files that the the extension or other external programs produce. If you are concerned about privacy, launch this add-on again with no text selected to replace the temporary file that contains the text you want to remain confidential. The paths and names of any temporary files directly created by the extension are shown in the Command and Script areas of the About... dialog.




Release List

Release Description Compatibility Operating Systems License Release notes   0.8.78 Enhanced Piper Speech Synthesis compatibility including Rhasspy Piper Server 6.4 Linux, Windows, macOS LGPL


  • On supported releases, the About dialog shows the application python version information as a tool tip when the dialog displays a python script. This allows developers to determine what libraries and commands are appropriate for new python code.
  • Remove unused code and some verbose comments.
  • Fix bugs and improved legacy platform compatibility.


  • The latest version of the application installed with Ubuntu LTS now supports the SourceForge library, so it can show the application python major version, minor version and patch level as a tooltip whether using the normal system Office suite, a Snap release or a Flatpak release.
  • When using the "(PIPER_READ_TEXT_PY)" --language (SELECTION_LANGUAGE_COUNTRY_CODE) "(TMP)" command, the About dialog suggests using the Pied app to install and manage Piper voice models.
  • If you use the Pied app to manage Piper voice models after already having installed voice models manually, the Piper client no longer tries to create virtual links to replace hard linked files.

Rhasspy Piper Server

Rhasspy Piper is a fast, local neural text to speech system.

A local network server version of Rhasspy Piper Server can serve a single voice model to different devices for a home network as an assistant to home automation devices or as a speech synthesis system for computer desktop applications that cannot run a locally installed piper program or model.

This Rhasspy Piper network client will only work correctly if the language of the model that it serves is the same as the language locale of the user. Use "(NETWORK_READ_TEXT_PY)" "(TMP)". Use a specific local network address to access a Rhasspy server that you host on another computer in your home network. For example,  with the default Piper server settings, you could use "(NETWORK_READ_TEXT_PY)" --url --voice piper "(TMP)".

When running the piper server in a command line window, it shows the following warning:

WARNING: This is a development server. Do not use it in a production deployment.

You can find out more about installing and using the server on the GitHub Rhasspy project) site. See also:

Download 0.8.76 Bug fixes, help and performance improvements; Update Linux alternate package support 6.4 Linux, Windows, macOS LGPL


  • Bug fixes, documentation and performance improvements.
  • Spanish help on supported platforms.
  • Images of Dialogues in Help on supported platforms.
  • When you enable Use Experimental Mode in your Office program, the settings are saved in a different file.
  • Note: To accommodate the improved settings behaviour, when you update this extension, or the version of Office, the settings will revert to their defaults.


  • AppImage application settings are saved in a different file than when you are using the standard application.
  • Snap support for Mimic3.
  • Flatpak support for PiperTTS and Mimic3.
  • Note: On supported architectures and platforms, the Pied application from the Snap or Flatpak App Store is an easy way to install and manage high fidelity PiperTTSvoices on your local desktop. You can listen to samples of Piper voice models using the online Piper samples page.

About Pied

Pied is a program for Linux distributions. When you first start the Pied program, it allows you to download the Piper speech synthesis program and compatible voice models. You can use Pied to choose the voice model that accessible programs like Firefox and Thorium ePub reader use to read text aloud. If a client program does not support selecting a particular voice from a voice model that includes several voices, then the program uses the first available voice.

If Pied has downloaded a voice model in a different language, but you have not set it as the default voice, Read extension can use that voice instead of the default voice using
"(PIPER_READ_TEXT_PY)" --language "(SELECTION_LANGUAGE_COUNTRY_CODE)" "(TMP)" in the command line options field.

Download 0.8.74 Options to enable or deny experimental features; Windows Piper support. `(RESET_ALL)` feature in main dialog` 6.4 Linux, Windows, macOS LGPL


  • Allow or deny access to third party scripts depending on the Office version and whether “Enable experimental features” in the “Options” or “Preferences” menu is enabled. (Resolves GitHub Issue 24).
  • Bug fixes and performance improvements.
  • Require Python 3.8 or higher to enable “Neural” text to speech platforms.
  • (RESET_ALL) feature in main dialog.


  • “Enable experimental features” replaces “Festival” in the main menu.
  • The MacOS system security settings now do not allow an extension to initiate a third party program like VideoLAN VLC, even if you have enabled “Enable experimental features” in the “Preferences - Advanced” menu. As a consequence, the options to save audio transcripts only include formats that are native to the platform.


  • The Rhasspy project released a Windows pre-release of it's Piper TTS software. Starting with Read Text 0.8.74, the extension supports it as an experimental feature on Windows x86_64 or amd64 machines.
  • You need to make sure that you have installed 64 bit versions of the most recent versions of piper, VideoLAN VLC Media Player and python, and that these programs are in your system paths.
  • You need to enable “Enable experimental features” in the “Options - Advanced” menu of the office application. The details are on GitHub.



  • Gstreamer paths are correct for computers using Debian 12 on legacy 32 bit Intel processors.
  • Gstreamer now exports open format files like .opus, .spx and .ogg using a standard format without metadata. The encoding rate for .opus is optimized for quality whereas .spx uses small file sizes that work well for speech recording.


  • Using the extension with Wine 9 works with supported computer architectures. Because of differences between Windows and Wine for Linux platforms, latency is higher and the risk of distorted speech is higher than it is on authentic Windows systems or on Linux distributions.
  • To use Piper TTS with Wine 9, install the 64 bit version of VideoLAN VLC and make sure that piper.exe is in the system path.
    • See the comments for Windows.
    • If you have voice models on the host Linux system, you can create a symbolic link in your host system to where Wine would store voices in it's directory. (i. e.: If you use the default settings, the command might look like ln -s ${HOME}/.local/share/piper-tts/piper-voices ${HOME}/.wine/drive_c/users/${USER}/AppData/Roaming/piper-tts/piper-voices).
    • To install Piper voices only in the Wine user directory, use Tools > Add ons... > Read Text... and include an option that includes a voice model for the current language and the --update True key/value string.
Download 0.8.72 Simplify first run. PLS lexicon export. Linux Piper replaces Larynx 6.4 Linux, Windows, macOS LGPL


  • On supported platforms, the first time you select text and click the toolbar button, the extension reads the selected text aloud using default settings instead of showing a dialogue. This makes it quicker and easier for new users to get started.
  • Bug fixes and performance improvements.
  • On supported platforms, enable export of x-sampa or ipa International Phonetic data using an XML format. The World Wide Web Pronunciation Lexicon Specification (PLS) is a standard way to describe pronunciation. For example, accessible ePub books can use PLS files to help reading systems pronounce uncommon words, place names and personal names correctly.
    • The PLS uses alias to refer to a sequence of words. For example, writers can use “W3C” to mean “World Wide Web Consortium”.
    • The W3C Pronunication Lexicon Specification uses phoneme to refer to an alternate spelling that uses a phonetic code.
      • IPA uses /ˈkænjən/ for canyon. The strings can include special reserved IPA characters.
      • X-SAMPA uses ["k{J@n] for canyon. The strings use standard ASCII code.
    • Specific language models might only support phonemes that are widely used in the language. As a result, they might not be able to pronounce some words correctly.
    • Specific language models might require a specific phonetic code - like IPA or X-SAMPA.
    • Each exported XML file includes only one regional pronunciation. Editors and publishers can optionally edit the file to specify pronunciation of specific words for other regions using a code editor.


The MacOS system allowed access to the phoneme editor even when phoneme substitution was not available using the default AppleScript scripting language. Now the extension disables right-click accessto editing phonemes from the tools button of the About dialog if python3 is not enabled.

  • MacOS only supports phonemic substitution if python3 is enabled in the main dialog. Some MacOS users might need to agree to the current “Xcode and Apple SDKs license” to use some features of this extension that use python code. You can view and agree or reject the Apple license agreement by entering the following in a terminal window: sudo xcodebuild -license.
  • Editing and using phonemic substitution requires you to enable/usr/bin/python3 in the external program field of the main dialog of the extension dialog instead of the default /usr/bin/osascript.


  • The file dialog for the saving a phoneme file did not suggest a file name. It now suggests a file name.
  • The extension can use StarBasic to generate SAPI text to speech if the Windows system wscript.exe program is not available.


Make it easier to add and select piper-tts voice models. Linux Piper replaces Larynx, because Larynx contributors can no longer update Larynx code.

  • The main menu includes some suggested voices for different languages.
  • When piper-tts is available, the main menu includes a menu item to update piper-tts metadata to include new languages and voices.
Download 0.8.70 Bug fixes; Linux `piper-tts` support. Speech rate support for Linux `mimic3` 6.4 Linux, Windows, macOS LGPL


  • Bug fixes.
  • Lexicon updates.


  • Support for LibreOffice 7.6.0 AppImage
  • Debian 12 and Fedora 38 clients use pw-cat from the pipewire-bin package to improve the latency of audio playback on low end systems.
  • Speech toggling worked correctly with localhost speech servers on Ubuntu 22.04 LTS but not with Debian or Fedora. Now when using Debian 12 and Fedora 38 and related platforms, the click to toggle off function of the application works as expected with system packages and AppImage packages.
  • Remove Festival voice support from the docker OpenTTS client, because the OpenTTS server does not work consistently with Festival across all supported platforms. OpenTTS Flite voices are a fast and reliable alternative.
  • Change the client’s timeout terminal troubleshooting message when a speech server unexpectedly fails.

Mimic 3

The Mimic 3 localhost client now supports changing the speech rate.

Piper TTS

Piper TTS is a fast, private local neural text to speech engine. Users can create or refine voice models based on a recording of a voice.

This client uses the piper engine to read text aloud using Read Text Extension with your office program.

Read Selection... Dialog setup:

External program:


Use the first available voice.

"(PIPER_READ_TEXT_PY)"  --rate 100% --language (SELECTION_LANGUAGE_CODE) "(TMP)"

Use a particular model (auto5) and speaker (45):

"(PIPER_READ_TEXT_PY)" --voice auto5#45 --rate 75% --language (SELECTION_LANGUAGE_CODE) "(TMP)"

Install piper-tts

If you are not online, then you cannot download voice models or configuration files. Once they are installed, piper handles speech locally.

Binary release

The binary release is fast.

The most recent binary piper executable program included in a piper archive for your computer's specific processor type. For example, piper_amd64.tar.gz works with x86_64 processors.

For example, for the piper_amd64 1.2.0 release, use the following:

python3 -c "import os;os.makedirs(os.expanduser('~/.local/share/piper-tts/'))"
wget -O ~/piper_amd64.tar.gz
tar -xf ~/piper_amd64.tar.gz -C ~/.local/share/piper-tts/
ln -s -T ~/.local/share/piper-tts/piper/piper ~/.local/bin/piper-cli
~/.local/bin/piper-cli --version

Use the following if you do not plan to also install the python release:

ln -s -T ~/.local/share/piper-tts/piper/piper ~/.local/bin/piper

Python release

The python pipx package has higher latency, but the piper script simplifies automating downloading the required onnx data and json configuration files. Some Linux platforms use python versions that are incompatible or only partially compatible with the pipx stable release of piper-tts.

Install the following packages:


Then use pipx to install piper-tts

pipx update-all
pipx install piper-tts
pipx ensurepath
piper -h

Audition and download a voice model

You can check the voice models online.

Review the voice model samples.

The first time you use this client, it will set up a directory to store piper voice models (onnx) and configuration files (json).


You can download the voice and configuration files for various languages and regions following the link on the piper-samples web page. Move the onnx and json files to the local piper-voices directory.

Read the README file in the directory for more information about using voice models for other languages and regions.

System-wide installation

If you want every account on a single computer to have access to piper then locate the contents of piper_amd64.tar.gz or the equivalent for your computer architecture in a directory that every account has read access to and link the piper application from the archive to a location that is in every user's PATH environment. For example,

sudo ln -s -T /opt/piper-tts/piper/piper /usr/local/bin/piper

If this piper client does not find user installed models and configuration files, it looks for global models and configuration files in:


Users can access the model in the directory from the client dialog using:

"(PIPER_READ_TEXT_PY)" --voice auto0#0 --rate 100% --language (SELECTION_LANGUAGE_CODE) "(TMP)"

If your Linux distribution includes packages to link speech-dispatcher with piper-tts, then you can configure the speech-dispatcher platform to use piper-tts:

Download 0.8.68 Updated `localhost` network speech platforms, MacOS & Linux bug fixes 6.4 Linux, Windows, macOS LGPL


  • Bug fixes and code readability improvements.
  • Lexicon updates.


  • Updated localhost network speech platforms.
    • The Mimic3 python library includes a gender table for supported models. You can instruct the program to ignore gender by using auto as the voice in the place of male or female.
    • Enable the OpenTTS network speech synthesis on supported platforms. OpenTTS can use a variety of Linux speech synthesis libraries. You can install OpenTTS using docker on supported Linux platforms. OpenTTS unifies access to multiple open source text to speech systems and voices for many languages.
    • Handle out of range voice id more consistently across localhost speech engines using modulus math. (i. e.: handle
      --language "(SELECTION_LANGUAGE_COUNTRY_CODE)" --voice "FEMALE10" when there are only 6 female voices currently available.)


  • Fixed a python network speech synthesis regression, so python users can use network speech as a fallback for an unsupported language.
Download 0.8.66 Support python3 pipx and additional libraries; Mimic3 server and Coqui AI serverLinux support 5.4 Linux, Windows, macOS LGPL


  • Bug fixes
  • Updated lexicons


  • Support for pipx (python pip using a virtual environment manager)
  • Better support for user installed pip3 libraries


  • Support for pipx (python pip using a virtual environment manager). The pipxlibrary allows you to install and run python applications in isolated environments. The pipx program replaces pip3 in Debian 12 and its derivatives.
  • Support for developer-oriented speech servers – Mycroft Mimic3 and CoquiAI TTS.
  • You can tell if the speech server is installed correctly if you can open a sample speech synthesis page in your web browser.
  • Use either server using an option that includes the string "(NETWORK_READ_TEXT_PY)" --language "(SELECTION_LANGUAGE_COUNTRY_CODE)" "(TMP)" in the Read Text Extension main dialog.
  • You can install spacy with pipx to reduce latency when using a local speech server with a long text selection. The spacy python library can intelligently split up long text selections into sentences.

Mycroft Mimic3

Mimic3 is a fast local neural text to speech engine for amd64, arm64 and armv7l processors. It’s available as an apt package for Debian or as a image.

  • The documentation tells how to set up a Mimic3 server using the Debian deb package manager or a application.
  • To test it out, use mimic3-server
  • Once installed you can test the server and install voice models by using a web browser to open a local webpage.
  • If you use the Read Text Extension dialog as described above, then the extension will try using mimic3-server first.
  • If you prefer normally the system’s speech-dispatcher voice as your main speech manager and Mimic for a secondary language, then use "(SPD_READ_TEXT_PY)" --language "(SELECTION_LANGUAGE_COUNTRY_CODE)" --voice "AUTO" "(TMP)" in the main menu. The "AUTO" voice name enables using the local mimic3-serverfor languages that the system’s speech-dispatcher does not support directly.
  • The instructions for Mimic3 describe how to set up speech-dispatcher to use mimic3 by default. In this case, you can omit the AUTO voice (i. e.: "(SPD_READ_TEXT_PY)" --language "(SELECTION_LANGUAGE_COUNTRY_CODE)" "(TMP)")

Read Mimic3 documentation and requirements for more details.


CoquiAI TTS engine is a deep learning toolkit for Text-to-Speech, mainly intended for use in research and production services. It includes a tool called tts-server that uses a local http service to allow web browsers and other programs that can connect to a local http server to convert text to speech. With the Read Text Extension network client you can check how new TTS models work with real world text. See tts-server --help

A server instance only serves one model at a time, but you can specify the language by selecting a model that includes the iso language code for the language in the model name. See tts-server --list_models

If you do not specify a model, then the server uses a female en-US model by default.

Example server commands

  • Default tts-server
  • English tts-server --model_name tts_models/en/vctk/vits
  • French tts-server --model_name tts_models/fr/css10/vits

Check the documentation for specific hardware and software requirements. Some voice models require system files that are not explicitly stated in the documentation. Best practice is to use TTS python libraries in a virtual environment by installing TTS using venv, pipx or tools. You can use the web page interface to test if the server works and if there are any problems with a particular voice model. If a model does not work at all, run the tts-server program in a command window and note any error messages that mention missing libraries or system packages.

Read Text Extension's python TTS client uses a few additional system packages - python3-bs4, python3-pip, pipx and espeak-ng. On supported Ubuntu distributions you can use:

sudo apt-get install python3-bs4 python3-pip pipx espeak-ng

To troubleshoot the server and the client, you can see information and error messages when you run the server and office program using separate terminal windows.

  • Server tts-server --model_name tts_models/en/vctk/vits
  • Client /usr/bin/libreoffice

Enable TTS server in the office program using the main Read Text Extension dialog with


If you prefer normally the system’s speech-dispatcher voice as your main speech manager and tts-server for an unsupported secondary language, then use

Download 0.8.62 Updates for MacOS 13.0.1 and Debian Linux 11.5 plus documentation updates and bug fixes 5.4 Linux, Windows LGPL


Clicking multiple times quickly on the main button on a legacy Windows system will not cause the application to open the Basic editor with an error message because of a request to delete a lock file that no longer exists.


  • MacOS 13 (Ventura) includes many new multilingual voices. Now, if you use /usr/bin/python3 as the application in the main extension dialog, you can select different voice profiles like “male2” or “female1” that select a male or female profile for every language that has both male and female voices.
  • On MacOS, python checks if Fiona and Lee are actually installed before allowing them as a voice option. These two voices appear in the say -v '?' response, but they are not installed by default in all regions.


Support the larynx-server speech synthesis platform.

  • Since the larynx-server Application Programming Interface (API) uses the http network protocol, supported snap and flatpak versions of office software that block speech-dispatcher can now use high quality speech synthesis with Read Text Extension.
  • The larynx package includes many high quality voices. You can manage languages and voices using a web browser pointed to a locally hosted web page.
  • Supported languages include Dutch, English, French, German, Italian, Russian, Spanish, Swedish and Swahili.
  • On Debian 11.5 compatible Linux platforms, you can use cinnamon-settings startup, gnome-tweaks or another similar application to set up larynx-server to automatically start up after 10-15 seconds when you log in. For testing purposes, you can also start the server by entering the larynx-server command in a terminal window.

    For someone who is blind, he/she cannot see the extension icon "Read Text". You should create a ShortKey such as Ctrl + R to read the highlighted text.

    • James Holgate Feb 23, 2024, 11:21 PM (4 months ago)

      This extension does not directly support keyboard shortcuts.

      However, users can create a keyboard shortcut for a macro by following these steps:

      * Go to *Tools > Customize*.
      * In the upper right corner, click *LibreOffice* or *Writer* to define the context in which the new shortcut applies.
      * In the Customize dialog box, select the *Keyboard* tab.
      * In the Shortcut keys section, select an unused key combination that you want to use. (i. e. : *Shift + Space* also known as `SHIFT_SPACE`)
      * In the Category list, select *LibreOffice Macros > My Macros > TextToSpeech > TextToSpeech*.
      * In the Function list, select *ReadTextAloud*.
      * Once the custom keyboard modification is complete, save the custom setting as a `cfg` file so that the custom settings can be restored or used on similar computers.

    It's a great program. It works through my Asus laptop speakers but **it won't work with headphones** either plugged in or Bluetooth. I tried it on my other laptop and it works fine. I thought it worked before on this one. Windows 10 Libreoffice 7.5. I have tried everything I can think of including reinstalling an older version of Libreoffice with no luck. Headphones work fine with other programs. Any thoughts?

      This might help, or it might not. Some laptops come with an audio enhancement app that allows you to set custom audio profiles for different sources, music styles and/or different outputs. You could look for a program with something like "SRS" or "Dolby" in the title to check the settings for headphones. You could also check the Device Manager to see if a different sound card driver solves your problem. Lastly, if the problem started when you updated the application, try using the 32 bit version if you are using the 64 bit version, or vice-versa to see if that helps.

    I find this to be an excellent extension and serves me perfectly. A pause feature would be awesome!!

    • James Holgate Mar 17, 2023, 4:59 PM (15 months ago)

      Thank you for your feedback!

      On some platforms, you can get the sound to play in a media player with a command line flag. For example, with Windows 10, use the `visible:"true"` flag...

      `"(TTS_WSCRIPT_VBS)" /visible:"true" /language:"(SELECTION_LANGUAGE_COUNTRY_CODE)" "(TMP)"`

      Once the sound file opens with the media player, you can pause, rewind, repeat and stop as you like.

      The information in the "About" dialog describes the available options for particular speech tools.

    Please check what the speaker pronounces.
    Pronouncing the character coding.
    Example, check five (5) characters:
    ( ) ' " &
    with Kubuntu 22.10 (Kinetic Kudu)
    with Libreoffice version and
    pico -V
    GNU nano, version 6.4
    read_text_2022.10.02_06.03.oxt 471.4 KiB (482,748 bytes)

      I can't reproduce the problem on Ubuntu 22.04, Fedora 37 or Debian 11. An application in your system appears to interpret XML incorrectly. Try updating your system and revising the extension to the newest version. If you are using a legacy system speech application, you might have better luck using a docker container like MaryTTS.

    read_text pronounces characters that ought not be spoken.
    Please fix readtext version 0.8.58

    In the very least, silence the following 7 characters:
    ( ) ' " | & _
    Because readtext version 0.8.58 says:
    ( as end-ash-40
    ) as end-ash-41
    & as end-ash-38

    read_text version 0.8.58 is installed:
    469.6 KiB (480,834) bytes
    and running on:
    LibreOffice version
    Operating System: Kubuntu 22.04.1

    Please fix readtext version 0.8.58

    0.8.52 does not work with
    Basic Runtime error. Line 4191

    • James Holgate Mar 17, 2023, 4:40 PM (15 months ago)

      Thanks for the information. I think it is fixed with the current extension and the current version of LibreOffice.

    It works well except that I can't find a reliable way for it to use the language code of a paragraph to determine which voice to use.

    If someone can provide that information, I can give this a 5-star rating!

    Loved this extension, but it seems to be broken with the new LO 7. Hoping this gets fixed sometime soon.

    Works great in MacOSX Mojave. Simple to install and uses the built-in Speech settings from the Accessibility preferences pane in MacOS.

    It works so well that I created an account here just to leave this review.

    Thank you it's perfect !
    Can you just add <node oor:name="OfficeNotebookBar"> to the code so I can see the extension in the tab mode ?
