Tetsy — text to speech with AI voices
Microsoft Azure neural voices on Android, as your system text-to-speech engine
Azure AI Speech has hundreds of natural neural voices across many languages, with expressive speaking styles — but Android can't use them as a reading voice on its own. Tetsy registers as a system text-to-speech engine and routes any text your phone wants to speak to Azure, then plays it back.
How to connect Microsoft Azure in Tetsy
- With your own Azure key. Paste your Azure Speech key and region into Tetsy — the voices appear in the voice picker. Usage is billed through your Azure subscription.
- With Tetsy tokens. No Azure account needed: buy a universal token package inside Tetsy and use Microsoft — and every other supported service — right away.
What you get
- Microsoft Azure as the system TTS engine: every app that reads aloud — e-book readers, browsers, translators — speaks with an Azure voice.
- TalkBack with a natural, human-like voice instead of the robotic default.
- Read articles, notes and whole books aloud inside Tetsy — Azure handles very long texts.
- Export speech to MP3, WAV or OGG audio files.
- Per-language settings: Azure for one language, a different engine for another.
