How to Make AI Influencer Videos in Another Language
Your AI influencer can speak Spanish, Portuguese, French or German without any translation feature. Here is how the script, the voice and the captions actually behave, and where they stop.
HexUGC generates short-form 9:16 videos from a reusable AI influencer you design once. Nothing in that pipeline is English-only. The script, the voiceover and the lip-sync all follow whatever language you put in, and there is no language setting to find because there is nothing to set. What HexUGC does not do is translate a video you already have. If you want your influencer speaking Portuguese, you write the video in Portuguese from the start.
The language comes from the audio, not from a setting
The voice model behind the voiceover step is multilingual, so it will speak a script in a long list of languages using the same voice you picked. The lip-sync step then receives your still image and the finished audio file, not the text. Mouth movement is driven by the sound, which means it does not care which language the sound is in. Get the script and the voice right and the rest of the pipeline follows without any special handling.
Write the script in the language you want
There are two routes through the script step. You can give a freeform direction in your target language and get a creator monologue back in it, editable before you generate. Or you can paste a script you wrote yourself, which skips the generation entirely. For a language you speak well, the second route is the better one. You are a stronger judge of whether a line sounds like a person than any model is.
One thing to watch: the duration estimate is built from word count at a normal English speaking pace. Languages that pack more syllables into fewer words can land a little short of your target, and looser ones a little long. Generate one, look at the running time, and adjust the script length next time.
Pick the voice by ear
The voice picker filters by source, accent and gender, and every row has a preview you can play. Language is not one of the filters, so audition rather than assume. A voice recorded by a native English speaker will usually carry that accent into Spanish, which is fine if your influencer is meant to be a foreigner living there and wrong if it is not. Your influencer gets a default voice stamped at creation, and you can change it per video in the create wizard, so trying three voices against the same script costs nothing but time.
Captions are the part that breaks
Captions are burned in from character-level timings the voice model returns, grouped into short cues by splitting on spaces, and rendered in a Latin-script font. For Spanish, Portuguese, French, German, Italian, Indonesian and the rest of that group, accents included, they behave exactly as they do in English.
For Arabic, Hindi, Thai, Japanese, Korean and Chinese, both halves of that sentence fail. Scripts without spaces between words give useless cue grouping, and glyphs outside the font will not render. The honest workaround is to untick "burn captions" in the create wizard and add captions in TikTok's or Instagram's own editor, which handles those scripts properly and is free. Better captions in the right script beat broken ones burned into the file.
What this does not do
It is not a translation or dubbing tool. There is no way to take a finished English video and produce a Spanish version of it, and no video translation feature is planned. If translating existing spokesperson footage is the actual job, that is a different category of tool, and our HeyGen comparison says which one.
It also will not produce the same video in five languages at once. One generation makes one video, and batch or multi-variant output is on our roadmap rather than shipped. There is no publishing step either, so you download the MP4 and upload it yourself.
Pricing does not change with language. A 10 second voiced video is 28 credits, and the plans work out at roughly 10 videos a month on Starter ($15) and 21 on Creator ($30). There is no free tier, so read the script aloud before you spend credits on it.
Finally, nothing here checks whether your script sounds natural to a native speaker. It will read fluently and still land as slightly foreign. If the account is meant to pass as local, get one person who lives there to read the first five scripts before you post them. The same discipline that keeps a character looking like one person applies to how it sounds.
