What This Workflow Does

This automation solves the expensive, time-consuming problem of making video content accessible to international audiences. Instead of hiring translators and voice actors or manually editing videos, this workflow automatically processes YouTube videos through AI-powered translation and natural voice dubbing.

When you send a YouTube link to your Telegram bot, the system extracts the video transcript, translates it into your target language (default Spanish), converts the translated text to natural-sounding speech using AI voices, and delivers the dubbed audio files back to you. What traditionally takes days and hundreds of dollars now happens automatically in minutes for pennies.

How It Works

1. Link Reception & Processing

You send any YouTube video URL to your configured Telegram bot. An AI agent within the workflow extracts the clean YouTube URL from your message, preparing it for content extraction.

2. Content Extraction with BrowserAct

BrowserAct executes a background automation task that visits the YouTube video, extracts the complete transcript, video description, metadata, and any available subtitles. This happens without manual browsing or copying.

3. AI-Powered Translation

Google Gemini processes the extracted text, translating it into your specified target language while maintaining context, tone, and natural phrasing. The system also intelligently segments the text into logical parts optimized for voice synthesis.

4. Voice Synthesis with ElevenLabs

ElevenLabs converts each translated text segment into high-quality, natural-sounding speech using AI voice models. You can customize voice characteristics, accent, speed, and emotional tone to match your brand or content style.

5. Delivery & Organization

The workflow compiles the dubbed audio segments, creates a translated summary, and delivers everything directly to your Telegram chat. Optional steps can save files to cloud storage or trigger notifications to your team.

Who This Is For

This automation is ideal for content creators expanding to international markets, educational platforms offering multilingual courses, marketing agencies localizing client campaigns, businesses with global training materials, and anyone regularly producing video content for diverse audiences. If you've ever thought "I wish my videos could reach Spanish/French/German speakers," this workflow makes that economically feasible.

What You'll Need

  1. BrowserAct account with the YouTube Translator & Auto Dubber template saved
  2. ElevenLabs account for AI voice synthesis (free tier available)
  3. Telegram account and bot token (created via BotFather)
  4. Google Gemini API access for AI translation
  5. n8n instance (cloud or self-hosted) to run the workflow

Pro tip: Start with ElevenLabs' free tier to test voice quality before committing. Their basic voices work surprisingly well for most content, and you can upgrade to premium voices later for specific brand requirements.
