Which has better avatar quality, HeyGen or Synthesia?

In a 40-video side-by-side test, HeyGen had slightly better lip sync for English (4.2/5 vs 4.0/5) and noticeably better Mandarin and Japanese output. Synthesia produced cleaner French and German lip shapes and its avatars move less, which many viewers read as more professional for corporate training. Neither has fully solved the uncanny valley at 1080p.

How many languages do HeyGen and Synthesia support?

HeyGen advertises 175+ languages for voice, but avatar lip sync quality varies by language. Synthesia supports 140+ languages and accents with more consistent quality on rarer European languages. For the 20-30 most common business languages both are reliable.

Can I use my own face as an avatar?

Both support custom avatars from your own likeness after a short consent video. HeyGen includes custom avatar creation on Creator and higher and processes it in 24-48 hours. Synthesia charges extra for personal studio avatars beyond the base subscription. Both require explicit consent verification and reject attempts to clone someone else.

Which is better for an L&D or enterprise team?

Synthesia. Its SSO, SCORM export, API maturity, restrained avatar movement, and European multilingual consistency fit corporate learning and development. HeyGen is the stronger pick for solo creators and social teams producing English or Asian-language vertical video.

How does this HeyGen vs Synthesia scorecard work?

You move six weight sliders (avatar realism, language support, price, API, editing ease, turnaround) to match your priorities. Each tool has a fixed 0-10 score per criterion from a hands-on test; the tool computes a weighted 0-100 score for each and declares the winner for your specific weighting. All computation runs in your browser — no data leaves the page.
