kghosh You can create. library message item with SUBMIT as text and it will get translated automatically to all the languages you have selected in your survey. You can then go to the block where the Submit button is located and change the Look and Feel for the block to the library item you just created. The correct translation of the text will be shown as long as the 'Submit' button text is a library item.

Thank you for your advise. I am sure I am missing something. I changed this as Library message in the steps below but button text is not changing based on my language selection. Kindly help checking this.

Hello TSAcc & TomG , Thank you for your guidance. It worked perfect. I had a code in CSS as to format the button text with a font which is not available in the target language. Thus it was not working. It worked with your solution as soon as I removed the custom code. Thank you so much and have a great day ahead.

Try this:
Create one hidden info note and mention text as "Next". Enter translation of "Next" text respective to each language. Then you can apply JS on header and can replace Next with Question text of that hidden info note. It will auto replace respective to each language.
