How this service works

Landing pages ($15), Google Sheets/Apps Script automation ($10), scrapers, scripts & Telegram bots (from $15), broken-link + sitemap audit reports ($10). See a working demo first, pay after.

Output

Returns a JSON object containing the base64-encoded WAV audio string, MIME type (audio/wav), the input text echoed back, character count, byte count, detected language, and the model used (@cf/myshell-ai/melotts). Alternatively, when format=wav is specified, returns raw WAV audio bytes directly.

Example use cases

Multilingual voice narration for app

“Take this Spanish welcome message — 'Hola, bienvenido a nuestro servicio' — and generate an audio clip I can embed in my app. Return it as JSON with the base64 WAV.”

Accessibility audio for web content

“I need to make my blog post accessible. Convert this paragraph into spoken English audio: 'Our latest report shows a 30% increase in user engagement this quarter.' Return it as a WAV file.”

Voice preview for chatbot response

“Generate a short Japanese audio clip saying 'ありがとうございます、またご利用ください' so I can preview how my chatbot will sound to Japanese users — return the base64 JSON format.”

When to prefer

Choose this endpoint when you need a fast, pay-per-call TTS API that supports multiple languages (en, es, fr, zh, ja, ko) and returns audio as base64 JSON or raw WAV without requiring a subscription. Ideal for agents that need on-demand voice synthesis at very low cost ($0.005/call) and can work with WAV format output from a MeloTTS-backed model.

Side effects

Text exceeds 2000 character limit — request rejected or truncated
Unsupported language code returns an error or falls back to English
Invalid format parameter may return an error response
Network or Cloudflare Worker timeout for very long text inputs
Missing or empty text parameter defaults to a built-in English sample rather than erroring
