TalkBack that sounds human

Text-to-speech 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.
