eSpeak

eSpeak is a text to speech application developed by F-Droid Open Source, packaged as a single Android APK of version 1.5 weighing in at 5.27 MB. The package targets Android 4.1+ and above. Below you'll find the publisher's own description, a quick spec sheet, and a short buyer-beware checklist so you know exactly what you're installing before tapping download.

1. Only download through the button on this page — never from third-party mirrors or shortened links, which are the most common way malware spreads.
2. File size is a light 5.27 MB, so it installs quickly even on modest connections.
3. This build is signed by "F-Droid Open Source" — always verify the developer name matches what's listed on the app's official store page before installing an update.
4. After install, Android may prompt you to allow "Install from unknown sources" — approve only this one install, then revoke the permission in Settings > Apps > Special access.
5. We link directly to the APK file or the publisher's repository; we do not modify the binary. Always run a virus scan after any sideloaded install.

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.

Features:

1. Includes different Voices, whose characteristics can be altered.


2. Can produce speech output as a WAV file.


3. SSML (Speech Synthesis Markup Language) is supported (not complete),
   and also HTML.


4. Compact size. The program and its data, including many languages,
   totals about few Mbytes.


5. Can be used as a front-end to MBROLA diphone voices.
   eSpeak NG converts text to phonemes with pitch and length information.


6. Can translate text into phoneme codes, so it could be adapted as a
   front end for another speech synthesis engine.


7. Potential for other languages. Several are included in varying stages
   of progress. Help from native speakers for these or other languages is
   welcome.

Is eSpeak free to download?
Yes. The APK file linked from this page is free. The developer may offer in-app purchases once installed, but obtaining the installer itself costs nothing.

What Android version does eSpeak require?
Android 4.1+ or newer. Installing on older devices may cause crashes or refuse to install.

Is eSpeak safe to install?
We link to the exact APK published by F-Droid Open Source. We do not modify the file. Still, as with any sideloaded app, scan it with a reputable antivirus before opening it, and only grant permissions the app genuinely needs.

How do I update eSpeak?
Install the newer version on top of the old one — Android will keep your data. If the signature differs, uninstall first (you may lose local progress).

Why is the app not installing?
Common causes: not enough storage, an older Android version than 4.1+, or a conflicting build already installed. Free up space, check your OS version, and uninstall any previous copy before retrying.

1. Tap the Download APK button above and save the file to your device.
2. Open your device Settings → Security (or Apps → Special access → Install unknown apps) and allow your file manager or browser to install unknown apps for this one file only.
3. Open the downloaded com.reecedunn.espeak.apk file from your Downloads folder.
4. Tap Install and wait for Android to finish.
5. Open «eSpeak» by F-Droid Open Source and grant only the permissions it actually needs.
6. Revoke the "unknown sources" permission once you are done installing.
