Hello Liu Shuwei ,
Thank you for your question!
I'm sorry but SCORM file generated from PDF cannot be translated automatically in browser even if you enable Google Translate extension in your browser. The issue relates to all PDF files, but not only to SCORM files.
We usually recommend to use Google Chrome, Mozila FireFox and Edge to view and complete iSpring courses. Explorer is not a recommended one.
Should you have any questions regarding to iSpring tools please feel free to contact us!
