Maise
On-Device Text-to-Speech for Android
A free, open-source Android TTS engine that synthesizes speech entirely on your device. 40+ voices, 9 languages, zero internet required.
Features
Fully On-Device
Speech synthesis runs entirely on your Android device using ONNX Runtime. Your text never leaves your phone.
40+ Voices
Powered by the Kokoro engine with voices across English (US/UK), German, French, Greek, Italian, Japanese, Portuguese, and Chinese.
System-Wide TTS
Works as a native Android TextToSpeech service — any app that uses the standard TTS API can use Maise automatically.
Streaming Playback
Producer-consumer architecture enables low-latency streaming audio output as synthesis happens, rather than waiting for the full result.
Voice Preview
The companion app lets you browse voices, preview synthesis in real-time, and set your system-wide default.
Maid Integration
Pairs with Maid for fully on-device AI conversations — local inference and local voice, end to end.
