Marmalade STT

Marmalade STT turns your speech into text on your phone. Use it as the voice input of your keyboard (FUTO Keyboard, HeliBoard, FlorisBoard and others), and of apps that ask Android for speech input. Your voice never leaves the device.

Private. Speech is recognized on the phone. Audio is never saved or uploaded

Offline. After a one-time download of a speech engine, it works without a connection

Live text. Shows your words in real time as you speak, on most engines

Knows when you're done. Smart Turn, the default for the speak-now popup, waits until you sound finished, so a pause to think rarely cuts you off

Multilingual. 100 languages, with the best engine for yours picked automatically

Clean output. Filler words removed, numbers as digits, your own replacements and verbal snippets

Free and open source. No ads, no accounts, no analytics

PRIVATE BY DESIGN

No analytics, no tracking, no crash reporting, no accounts, and no server of ours. The internet is used only to download the speech engines you choose, from GitHub, and every file is checked against a pinned SHA-256 hash. Android backup is turned off, so nothing is copied to the cloud.

YOU DECIDE WHEN IT STOPS

In the speak-now popup and other apps, Marmalade uses Smart Turn v3 technology by default to detect when you have finished speaking. No hands required. Does it cut you off too early? Switch to stopping at a pause, or set an end word instead. On the keyboard it listens until you tap, or it can use Smart Turn too.

CLEAN TEXT

Optional cleanup fixes capitals, and in English removes filler words, turns "new line" and "period" into the real thing and writes numbers as digits. Replacements for names the engine gets wrong, and snippets for text you type often, work in any language.

WORKS WITH YOUR KEYBOARD

Turn on "Marmalade voice typing" and your keyboard's mic key opens a small Marmalade panel that types what you say. It works with FUTO Keyboard, HeliBoard, FlorisBoard, AnySoftKeyboard, Unexpected Keyboard, AOSP's keyboard and others with a voice key.

AN ENGINE THAT SUITS YOUR PHONE

The setup guide recommends a speech engine for your language and for your phone's memory and speed, with the option to download and try out other models.
