Is Piper Text-to-Speech Voices safe?

Clean risk

Piper Text-to-Speech Voices sends text submitted for speech synthesis to piper.ttstool.com.

When Chrome asks the extension to speak text, it forwards the utterance text and speech options through its extension page to an iframe loaded from piper.ttstool.com. That remote Piper web app performs the speech synthesis and sends playback events back to the extension.

    Where it sends data

    Destinations our analysis observed Piper TTS contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
