How to Use Subtitle Translator

Vovsoft Subtitle Translator supports offline and online translation engines:

• Argos Translate, which is an offline translation library
• Microsoft Azure Cognitive Services API, which can translate up to 2,000,000 characters per month for free
• IBM Cloud Language Translator API, which can translate up to 1,000,000 characters per month for free

👉 How to configure Argos Translate

Argos Translate is a translation library that works offline, supporting 30+ languages. Translations you make with Argos Translate may be a little slow because it uses your computer's hardware resources. Additionally, the translation quality is not as good as online APIs.

Argos Translate requires Python installation. We recommend Python 3.8.6 to avoid library incompatibilities.

After installing Python, please restart Vovsoft Subtitle Translator. When you click the "Translate" button for the first time, the software will install the base library, requiring approximately 1GB of storage on your computer. Moreover, the software will automatically download the language packs as needed.
