# VoiceHue
> VoiceHue is a free online text-to-speech tool (TTS) that turns text into natural-sounding speech in your browser. Paste up to 3,000 characters, pick a voice and listen. No sign-up and nothing to install.
## Available now
- Text to speech in the browser, free and without sign-up.
- Up to 3,000 characters per conversion.
- Natural voices from your device and browser.
- Speech generated on your device in English, Spanish, Portuguese and French.
- Cloud voices in English, Chinese, Spanish, French, Japanese and Korean, with MP3 download.
- Adjustable speech speed.
- Works on desktop and mobile browsers.
- Free to use; no account or credit card needed.
- A developer API: OpenAI-compatible text to speech at POST voicehue.com/v1/audio/speech with API keys. The free plan gives each signed-in account up to 2 keys with 10,000 characters a month, 2,000 a day and 10 requests a minute per key, standard voices only. GET voicehue.com/v1/voices lists the voice ids, no key needed.
- A remote MCP server for AI assistants and agents at voicehue.com/mcp (Streamable HTTP, JSON-RPC over POST, header "Authorization: Bearer <VoiceHue API key>"). Tools: text_to_speech, list_voices. The same keys and the same free plan as the API; audio is returned as MP3 (default) or WAV.
- Share links for generated audio: the Share button next to Download MP3 creates a public link that anyone who has it can open. Links last 90 days, the creator can delete them at any time, and each shared page has a report button. A link holds only the text, the voice and its settings; the audio is generated when someone presses play.
