Work in this order: approve the source, approve the translation, generate the voice, and listen to it inside the video. Budget at least one correction for every language, and check price and availability separately for each country where you will use it.
01Approve the source before translating
Check names, product names, numbers, claims, formulas, and required notices in the source script. Translators can then make each language sound natural without changing the facts. If you generate audio too early, a script change can force you to redo the voice, captions, timing, and video export.
02Compare voices with the same short script
TTS means software that reads written text aloud with an AI voice. Use the same 30-to-60-second script to compare language support, name pronunciation, voice consistency, measured usage, and commercial-use terms. If you also use an avatar or lip sync, which matches mouth movement to audio, check the finished video for timing problems.
03Treat language and country as separate choices
Spain and Mexico both use Spanish, but currency, available plans, tax notes, and destination links may differ. The same applies to French in France, Canada, Belgium, and Switzerland. Let users choose their country instead of guessing it from browser language or internet location.
04Include one correction round for every language
Budget for translation, word choice, pronunciation fixes, a new voice generation, caption changes, timing, and a final check inside the video. Record characters or audio minutes for each language, and separate the amount included in the plan from extra usage. The TTS and multilingual-video calculators can show these costs.
