Airy

Airy Studio is a browser based text to speech workspace. You type a script line by line, pick a voice and a generation language, listen to the take on the spot and export it as an audio file. Signing in stores the work as projects that can be reopened and edited later, and a toggle plays each take the moment it finishes generating.

A speech to text mode that records what you say and keeps it as text is marked inside the app as coming soon. The interface ships in English and Korean. The service describes itself as a beta whose features are still changing.
