About CoeFont

CoeFont is a voice synthesis service centered on Japanese, and its focus is the size of its voice library and letting you turn your own voice into one. Its plan table lists a library of more than 10,000 AI voices, including voice actors. You can record your own voice in the web app, and Enterprise can also build one from existing video or audio (annual billing, charged separately). The API for bulk generation starts at the Plus plan. The free plan is non-commercial.
