Node.js TTS (Text-to-Speech) Integration

Automated text-to-speech synthesis tool using speechsynthesis.online | Convert text to natural-sounding MP3 audio files with Node.js | Browser automation with Patchright/Playwright | Free TTS API alternative | Multi-language voice synthesis | SSML support | Cloudflare bypass

📖 Overview

A powerful Node.js text-to-speech (TTS) automation tool that leverages the speechsynthesis.online web service to convert text into high-quality MP3 audio files. This project uses Patchright (an enhanced, undetectable fork of Playwright) for robust browser automation, making it an excellent free alternative to paid TTS APIs.

Perfect for: Voice-over generation, audiobook creation, accessibility tools, language learning applications, content creation, podcast automation, and any project requiring programmatic text-to-speech conversion.

🚀 Key Features

• SSML 1007 Error Fix: Automatically resolves the common "Prefix redefined" error by intercepting requests and cleaning up XHTML namespaces.
• Cloudflare Turnstile Solver: Built-in logic to automatically detect and bypass Cloudflare verification (captcha).
• Incognito (Clean) Mode: The tts_clean.js script opens a fresh session each time and clears temporary data after completion.
• Ad Blocking: Advertising modules and analytics scripts are blocked to save bandwidth and improve speed.

📂 Project Structure

• tts.js — Main script. Uses a persistent profile (pw_profile) to maintain cache.
• tts_clean.js — Optimized "clean" version. Opens a new temporary profile each time and doesn't load unnecessary resources except CSS/Images.
• voices_info.json — List and metadata of all available voices in the system.

⚠️ Important Notes

1. Website Stability: The speechsynthesis.online website may occasionally fail to work properly due to technical issues or strict Cloudflare verification. In such cases, the script may throw "Timeout" or "Target page closed" errors.
2. voices_info.json: This file contains many voices, but some may be temporarily unavailable on the website itself.

🛠️ Installation and Usage

npm install

Running:

# Using the main script (you can change the text)
