FreeTTSとは？

FreeTTS is an online audio toolkit for text to speech, speech to text, vocal removal, voice enhancement, and browser-based audio editing. It combines free local tools with AI Cloud TTS for users who need more voice generation capacity.

The site separates browser audio tools from paid AI Cloud Text to Speech usage. That means you can work with transcription and editing tools in the browser, then use monthly characters or top-up credits only when a project needs cloud-generated speech.
