Text to speech without internet on Android: set it up, then test it

How Android speaks text

Android has a text-to-speech engine: the part of the phone that turns written words into a voice. Apps that read aloud, from e-book readers to many AAC apps, hand their words to it. Which engine you have depends on the phone: Google’s engine, the phone maker’s own, or one you downloaded from Google Play.¹ On many phones Google’s engine is already there as Speech Recognition & Synthesis, which “powers applications to read the text on your screen aloud”.²

The engine only works offline if a voice for your language is stored on the phone. Google says that “in some countries or regions, you may only be able to download a single, high-quality voice for offline use”.³ Google doesn’t promise in plain words that every voice works with no connection, which is why the test below matters more than any setting.

Install a voice on the phone

Google’s steps, for phones that use Google’s engine:³¹

1. Open Settings, then Accessibility, then Text-to-speech output. On some phones it sits under a different menu; type “text-to-speech” into the search box at the top of Settings.
2. Choose the preferred engine. Google’s is listed as Speech Recognition & Synthesis from Google, or Speech Services by Google.
3. Tap the settings icon next to “Preferred engine”, then Install voice data.
4. Choose your language or locale, for example English (United States), and let it download over Wi-Fi. Some languages offer more than one voice; pick the one you like, and download it.
5. Back on the text-to-speech page, set the speech rate and pitch, and press Play to hear a short sample.¹

Test it with no internet

Do this at home before you need it, not in a hospital corridor with no signal:

1. Charge the phone, then switch on airplane mode and check that Wi-Fi is off too.
2. On the text-to-speech page, press Play. If you hear the sample, the engine has a voice on the phone.
3. Now open the app you will really use, type a long sentence with a name in it (“Please call my sister Maria”), and make it speak.
4. Try a saved phrase as well as typed words: some apps store recordings for saved phrases and use the engine for new words, or the other way round.
5. Restart the phone and test again in airplane mode, and test once more after the next system update.

If the sample plays but the app is silent, or says it has no connection, the app uses its own online voice rather than the phone’s. Look in the app’s settings for an offline or “device” voice.

Which apps speak without internet

What each app’s own listing or website says about working offline, for apps people use to speak for them on Android:

Speaking without internet, as each app’s listing or site says (October 30, 2026)

“Uses the phone’s voice” means the app speaks with the engine you set up above, so do that first. Tap AAC is different: its voice, Bella, is part of the app itself, recorded words and phrases first and a small voice model on the tablet for the rest, so it talks with no set-up and no connection.⁵ It can also use any voice installed on the phone instead.⁴

Built-in tools that read, but don’t talk for you

• Select to Speak reads aloud what is already on the screen: “you can select items on your screen and hear them read or described aloud”.¹⁹ It reads a message you received; it doesn’t give you a box to type your own words.
• TalkBack is Android’s screen reader, for people who can’t see the screen.²⁰
• Live Transcribe can say a typed message out loud: see how to make your Android phone say what you type.

If the voice sounds robotic

• Install voice data again and try the other voices for your language, if there are any.
• Slow the speech rate down a little: fast speech from a small phone speaker is the hardest to follow.
• Some apps offer their own, more natural voices. Check whether those need the internet before you rely on them.
• For someone who will speak this way every day, the voice matters. Try several apps before you pay, and ask the person which voice feels like theirs.

Keep a backup that needs no battery

Any phone can run flat or break. A printed alphabet board or a few phrase cards in a bag mean a person can still spell or point. Our free alphabet board prints on one page.
