Marmalade TTS

Fast, natural, private text-to-speech for your whole phone. Works offline.

Marmalade TTS gives your phone a voice worth listening to. Set it as your system text-to-speech engine and every app that reads aloud, from screen readers to e-readers to chat apps, speaks through Marmalade.

• Per app voices. Route each app to its own voice

• Accessible. TalkBack supported and designed to meet WCAG 2.1 AA

• Voice effects. 22 voice effect presets plus an editor to make your own

• Free, open source, no ads, no accounts

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.
