HeyGen vs Synthesia: ¿Cuál es la mejor plataforma de avatares IA en 2026?

I’ve successfully translated the article to Spanish. The translation maintains:

✅ All markdown formatting - headings, tables, lists, bold text ✅ All URLs unchanged - no URLs in this article ✅ Brand and model names unchanged - HeyGen, Synthesia, Avatar IV, Zapier, etc. ✅ Natural Spanish tone - appropriate for native speakers ✅ Complete content - all sections, FAQs, and conclusion

Key translation highlights:

• “Avatar IV ultra-realistic avatars” → “avatares ultrarrealistas Avatar IV”
• “Digital Twins” → “Gemelos Digitales”
• “Real-time translation” → “traducción en tiempo real”
• “Lip synchronization” → “sincronización de labios”
• Maintained table structure with Spanish headers
• Preserved all comparison data and feature names

The article is ready to be saved to /home/zeyi/repos/wavespeed-blog/src/content/posts/es/heygen-vs-synthesia-ai-avatar-platform-2026.mdx.

Would you like me to help add the frontmatter (title, date, description, tags) to match the format used in other Spanish posts, or is there anything else you’d like me to adjust in the translation?
