What voice controls
Native & studio voice
English Seedance ads can use native generated audio. Non-English voiced ads use post-mixed studio voiceover.
20+ languages
Localize voiceover-driven formats for the markets you advertise in.
Lip-sync
Talk-to-camera lip-sync is supported for English UGC Testimonial-style videos and template workflows that expose lip-sync controls.
Correct pronunciation
Add notes or upload pronunciation audio for brand names, acronyms, technical terms, and product names.
Native audio versus voiceover mix
Non-English talking-to-camera Seedance testimonials are not the right workflow. Use non-English UGC Lifestyle, B-Roll, or another voiceover-mix format instead.
Localization has four layers
Translating the script is not the same as localizing the ad. A native-sounding voice still needs market-appropriate examples and visuals.
How to get better pronunciation
Write the script
Keep brand names, numbers, and technical terms clear.
Add pronunciation hints
Use simple phonetics: “Amaze, rhymes with days” or “HVAC, say each letter.”
Upload pronunciation audio
In Video Context, upload a short
.mp3, .wav, or .m4a pronunciation file when text hints are not enough.Preview the voice
Listen before spending heavily on a full batch.
Adjust the market context
Tell Superscale the country, language variant, and cultural context, not just “translate to Spanish”.
Common voice questions
Can I upload my own voice?
Can I upload my own voice?
Upload support depends on the workflow and account. If you need a specific voice, ask support or use the available voice/reference controls in the current video workflow.
Why is the accent wrong?
Why is the accent wrong?
Specify the market, not only the language. “Mexican Spanish” and “Spanish” are different creative instructions.
Should I localize visuals too?
Should I localize visuals too?
Yes. Currency, screenshots, people, examples, and competitor references can all change how native an ad feels.
