Voice & audio
What it does
Feed it dialogue marked up by speaker and it produces audio of two people talking, complete with pauses, interjections and laughter rather than two voices reading in turn - which makes it usable for podcast-style material or language-teaching examples. It is built around English; Japanese scripts come out awkward and mispronounced. Long scripts degrade, so work in short sections. Text is sent to the host's servers.
Summary based on the project's own description. The Japanese page has a fuller beginner guide: setup difficulty, what to prepare, and a step-by-step start.
