ScriptVocalizer supports 24 languages in total. You can directly type or paste your script in any of those languages in ScriptVocalizer. Select that language from the drop down and select the voice-over which you want to use, then simply click Create.
Please note that, ScriptVocalizer is not a translator. So in case you have your scripts in English and you want to change it to other languages, you may use Google Translate to translate your script. Then you can paste the translated script inside ScriptVocalizer. ScriptVocalizer would accept translated scripts by Google Translate.
Here is a work demo where we used Google Translate to translate our script from English to Chinese and use that Chinese script in ScriptVocalizer to create a Chinese Speech.
