When you have a global customer base, a bot talking to your customers in a language they best understand will improve your customer support and CSAT rating. With the bot builder, you can configure multiple languages in a single pane, thus making your bot, polyglot. If a particular conversation needs to be updated for another language, you can access it in the bot builder and update the conversation for just that language.
A quick guide to setting up multilingual bots:
Log into your bot builder account as an Admin/Owner
Make sure you have the right bot version selected from the drop-down
Click on the 'Add New Language' option and add all the required languages from the drop-down
Download the main language’s bot script by clicking on the 'Download original script' option
Replace the main-language text with the required translations in the script and upload the updated file against the corresponding language inside the bot builder
You'll also know when the file was last updated
