The studio’s controls are in English. In Script, choose the language for your AI draft, including German (Germany), French (France) and Portuguese (Portugal or Brazil). Your existing text stays as written when you change this choice. You can also paste lines in Spanish, German, French or another language and the voice speaks that language, detected automatically from the text. Budget voices read English only. A script in another writing system is refused there before any credits move, but Spanish, German and French share the English alphabet, so a Budget voice accepts those lines, bills them and reads them with an English accent. For any language but English, pick Premium or Pro.
Every Premium voice reads at least English, German, Spanish, French, Italian, Portuguese, Russian, Turkish, Arabic, Hindi, Indonesian, Japanese and Korean, and many read 50 or more, adding Chinese, Polish, Swedish, Ukrainian and others. Pro voices read 29 languages, adding Danish, Finnish, Czech, Slovak, Croatian, Bulgarian, Romanian, Greek, Tamil, Filipino, Dutch and Malay. Use the Voice language filter in the picker to see matching voices. You can also search for a language by name. Each matching voice shows that language beside its language count.
The free preview plays one fixed English sample line for every voice, whatever language your script is in, so hearing English there says nothing about your program. To hear a voice in your language, keep three to five lines in the editor and synthesize them with a single voice. That costs a few credits and plays the real thing.
The regional Script language choice guides vocabulary, spelling and grammar. Voice accents vary, so it does not promise a particular national accent. Listen to a short generated script before making a full program. To use your own accent, add “Your Voice” in the picker and read the lines yourself.
