Select a Language and Voice
Add your text in your chosen language into the script box.
Synthesia automatically detects the language.

Review the recommended voices and accents for your avatar at the top of the selection panel.
Use the search bar to find additional voices.
✍️ For non-English content, preview the voice before you generate. For pronunciation-critical scripts, ask a native speaker to review the output.

Start a new line for each language.
Confirm whether the voice updates automatically.
Synthesia will often auto-detect the language and switch to the appropriate voice if one is available.
If the voice does not update automatically:
Select the speaker pill for the line that did not update.
Select the voice selection dropdown on the speaker pill.
Select Back to all languages.
Search for the language of your text.
Choose a voice that matches the language.
If the same voice is not available in that dialect, choose a voice from a different dialect.
✍️ Accent coverage, and available variants differ by language. Not all voices are available in every language or dialect. For example, a voice available in Spanish (Mexico) may not be available in Spanish (Spain) or Spanish (United States).
