   • Vidéos d'avatars IA parlant à partir d'un script texte
   • Pistes de musique générées par l'IA
   • Prototypes de produits imprimés en 3D
   • Feuilles de calcul et rapports financiers
2. When using a stock avatar with a prepared script, what can Synthesia do?
   • Create presenter narration without a new on-camera shoot
   • Guarantee a finished video in every language and style
   • Remove the need to review generated speech or visuals
   • Create a personal avatar without recording or consent
3. What does Synthesia’s stock-voice help page say about language availability?
   • Every avatar supports every language and accent
   • The count is exactly 140 voice recordings
   • Stock voices are available across more than 140 languages and accents
   • Only English is supported
4. What is the difference between Synthesia’s content moderation and C2PA credentials?
   • Moderation verifies factual accuracy; credentials guarantee legal ownership
   • Both features guarantee a video was never edited
   • Credentials block restricted scripts while moderation identifies the signer
   • Moderation enforces platform content policies; credentials expose signed provenance metadata
5. Which statement distinguishes Synthesia’s current photo avatar from its legacy video avatar?
   • Photo avatars use a still image plus consent video with optional voice cloning; legacy avatars use recorded video footage
   • Both require the same full-length video training capture
   • Photo avatars require no identity consent
   • Legacy avatars are created from a text prompt only
6. What must match during Synthesia’s photo-avatar consent check?
   • The photo background and a stock avatar
   • The person in the uploaded photo and the person in the live consent video
   • The video language and the avatar’s default voice
   • The user’s account email and the image file name
7. How does Synthesia treat avatar appearance and custom voice selection?
   • Every avatar automatically clones its owner’s voice
   • A voice clone can only be used with the legacy video-avatar type
   • They are separate choices, so a supported voice clone can be selected independently of an avatar
   • Changing a voice changes the source photo
8. What should a user check before choosing an avatar language and voice?
   • Assume every avatar supports the same language list
   • Assume the avatar voice is cloned automatically
   • Use a language count from an older product page
   • The current options for the selected avatar, product, and plan
