Switching language using intent trigger

The most common way to have users choose their language of choice is using the ask: language node when the language selected by the platform isn't correct.

Another way of offering users to change their preferred language is by building an intent trigger in your flow that then triggers the switch language node to switch to the right language.

In this example we are going to offer a way to switch to the dutch language, but using this example you can implement any language switch.

1. Train a global intent

Go the the AI section and open the Intents page. Add an intent called "Switch to dutch".

2. Add an intent trigger to your Playbook

Go to the Flows section and open the Playbook. Now right click on your canvas and choose to add an Intent trigger to the flow:

Create intent trigger

Now pick the intent you just created in the side panel of the newly created intent trigger by clicking on the pick button and select the intent switch_to_dutch.

Configure the intent trigger to trigger on the newly created global intent

3.Add Flow control: switch language

Now drag a line from the newly created intent trigger node and pick the Switch language node in the Flow control menu.

Add flow control: switch language

Now configure it to switch the the dutch language by picking the language in the drop down. When the language isn't available, you might need to add it in your bot settings first. Go to the bot identity page for this in settings.

Configure the switch language node

4. Add Flow control: restart

Now when the language is changed while a conversation is in the middle of an Ask node or Iterate node, the App will still repeat the text in the previous language. This is because the ask and iterate texts are already loaded in memory. The only way to solve this is by restarting the conversation. This can be done by dragging a line from the newly created switch language node and add the node Flow control: Restart.

Now the conversation will restart in dutch after having switched to dutch by the global intent.
