# Tetsy

> Tetsy is an Android text-to-speech app that connects AI voices from ElevenLabs, OpenAI, Microsoft Azure, Google, Amazon Polly, IBM Watson and Speechify to your device as the system TTS engine.

Tetsy is the bridge between an Android device and the major speech synthesis services. Instead of a separate app per provider, it sends your text to the service you choose and returns ready speech — with the same simple interface for all of them.

## Features

- System TTS engine routing: pick ElevenLabs, OpenAI, Microsoft, Google, Amazon or any other engine. Tetsy registers as an Android system TTS engine and routes text to the chosen service.
- Read texts and books aloud: paste a note, an article or a whole book and listen to it.
- Audio export: any text can be exported to MP3, WAV or OGG — for a player, a podcast or an archive.
- Natural TalkBack voice: with Tetsy as the system engine, TalkBack reads interface elements in a natural AI voice instead of a robotic one.
- Per-language voice settings: different services and voices for different languages, applied automatically.
- Read from anywhere: select text in any app and voice it through the system text-selection menu.
- Local engines: another TTS app installed on the device can act as the synthesizer too; local engines work offline.
- API key or tokens: connect your own provider API key, or buy universal Tetsy tokens and use the services without registering with each provider.
- Speech tuning: speech rate and pitch settings where the provider supports them.

## FAQ

**Do I need an ElevenLabs or OpenAI account?**
No. Connect your own API key, or buy universal tokens in Tetsy and use services without a separate sign-up.

**Can I save speech to a file?**
Yes. Any text exports to MP3, WAV or OGG — for a player, a podcast or an archive.

**What does the TalkBack pairing give me?**
Tetsy becomes the system TTS engine, so TalkBack and other apps read text in a natural AI voice.

**Does it work offline?**
Yes, with a local engine installed on the device. Cloud services need an internet connection.

## Platforms

## Pricing

- The app is free. Use your own provider API key, or buy universal Tetsy token packages that work across all connected services without a separate account at each provider.
