Sume Avatar 1.0 speaks English only. HeyGen's Avatar V page lists 175-plus languages with phoneme-level lip sync, so if you need a spoken language other than English, Sume's avatar video route does not cover it. Voice cloning is available in the Sume app only, not through the API.

What does HeyGen say?

HeyGen's Avatar V page, read 2026-10-02, says the avatar is built from 15 seconds of webcam footage, speaks 175-plus languages with phoneme-level lip sync, has no cap on generated length and shows no identity drift across a 30 second clip or a 10-minute module. These are HeyGen's own claims. The page lists no price.

What can I do on Sume for other languages?

Sume has no avatar speech in other languages. The clip route that exists is the avatar video job, which is English only. If your script is English, it works as documented. If it is not, use a tool that lists your language and bring the result into Sume's Timeline or captions steps if you need them.

Do captions help?

Video captions are $0.20 per job and burn text onto a video. They do not change the spoken language of an avatar. Captions in a second language over English speech would give a mismatch, so do not use them as a substitute for dubbing.

What if I only need the face?

Avatar creation is $0.95 per avatar and produces a face from a prompt, props or a photo. You can then use that avatar in an English video. The face is independent of the language, but the speech is not.

How should I choose between them?

Start from the language list. If your audience needs a language outside English, Sume's avatar route is out. If the script is English and you want an API with listed per-second prices, check the tier rates against your length. Neither page proves quality for your footage, so run a short sample on each before you commit to a long module. Sume's docs list the exact limits and error codes for each call, so read the page for the endpoint you use before you build on it, and keep a short note of which limits applied to your run, so a later change is easy to spot. If a call is refused, the error code names the cause, and fixing that one input is usually enough to retry safely with the same Idempotency-Key.
