What is Translation Auto-Validation feature?
If your language ability is limited, to ensure the most accurate translation, enabling "Auto-Validation" would be a good choice.
It will re-translate the translation into your spoken language for a second confirmation after your input message is translated.
This can greatly avoid problems with incorrect translations.
As shown in the above image, once the input message has been successfully translated, it will be re-translated into your spoken language for display.
Now, you can easily compare and check for any translation issues.
