WORKS EVERYWHERE

Marmalade implements Android's standard text-to-speech interface, so it is a drop-in replacement for Google or Samsung TTS. Pick it once in Settings and it powers spoken text across your apps.

READY OUT OF THE BOX

A fast English voice is built in, so Marmalade speaks offline from the first launch. Bigger and better engines download only when you choose them, and text read by on-device voices never leaves your phone.

A VOICE FOR EVERY APP

Marmalade is built around aliases. Build your favorite voice with speed and effect settings. Route apps to aliases and your e-reader can speak in one voice while your chat app uses another. Anything unrouted follows your primary alias.

SPEAKS 8 LANGUAGES

The multilingual Kokoro engine speaks English (US and UK), Spanish, French, Italian, Portuguese (Brazil), Hindi, Japanese, and Mandarin Chinese. It detects the language as it reads and switches pronunciation on the fly.

PRIVATE, WITH OR WITHOUT THE CLOUD

No analytics, no telemetry, no accounts, and no backend of ours. On-device voices touch the network only to download the engines you pick. If you want voices beyond what your phone can run, add a cloud engine with your own API key. Providers include Venice.ai, which says it does not store or log requests. Until you set one up, nothing you read ever leaves your phone. Note: other providers may log requests. Refer to their privacy policies.

BUILT FOR SCREEN READERS

Marmalade is accessible with rich TalkBack support and designed to meet WCAG 2.1 AA with a high-contrast dark theme. Every control is labeled, and progress and errors are announced aloud when TalkBack is enabled. Nothing an assistive-tech user needs sits behind a purchase.

MAKE IT YOURS

22 built-in effect presets like 8-bit, cyborg, megaphone, and vintage radio give spoken output character. Or build your own effect chains in the editor.

READS THE LONG STUFF

A foreground playback service reads long text reliably with the screen off, with lock-screen and Bluetooth controls. Share text from any app, use the system "read selection" action, or speak your clipboard from a Quick Settings tile.

OPEN SOURCE

Marmalade's own source code is MIT licensed and its repository contains no GPL code. The published app also contains the espeak-ng phonemizer, compiled from source at build time, so the app you install is distributed under GPL-3.0-or-later. The exact espeak-ng version used is pinned from the project repository, and license details for every component are shown inside the app.
