How many languages do AI avatar tools list? Six pricing pages

On their pricing pages, Creatify lists 75+ languages, Colossyan 120+, Synthesia 140+ and HeyGen 175+ dialects, while Captions lists captions in 100+ languages and Tavus's consumer PAL plan lists 30+. Sume's avatar documentation does not publish a count of spoken languages, so the only honest answer is to test your language with a short clip.

What each page says

These are marketing counts. They mix spoken voices, dialects, translation targets and caption languages, so they are not directly comparable.

What Sume documents

The avatar video guide says nothing about a spoken-language list. It documents a caption language hint, and Hangul caption styles for Korean speech: a Korean script with the slam, punch or tiktok-green style is rejected with 400 caption_hangul_text_latin_style.

So caption support for Korean is explicit, but spoken-language coverage for the avatar voice is not a documented promise. I would not publish a claim for any language you have not heard rendered.

A cheap test

A clip must be at least 4 seconds. At the standard rate of $0.184 a second, a 4-second test costs $0.736, and a 10-second test costs $1.84. Run one clip per target language with a native-speaker script, and judge pronunciation, pacing and mouth movement.

Do this on the tier you plan to ship. Tier changes the render, so a standard-tier pass is not proof for max. Keep the test script in the same language as the final one, and have a native speaker listen before you commit a campaign budget.

How to read a language count

A count is a ceiling on where you might work, not a promise of quality in each language. Ask three things: is the voice native or accented, does mouth movement match the sounds, and does the caption font cover the script. Sume documents only the last for Korean, through Hangul caption styles.
