Deploying a Multilingual Azure Health Bot in Web Chat

Question

How can I deploy a multilingual Azure Health Bot in a Web Chat interface? I have successfully set it up in the management portal, including adding localization. However, I am unsure of the steps required to deploy this multilingual functionality in a Web Chat interface. Any guidance on how to do this would be greatly appreciated. Thank you!

To implement a multilingual Azure Health Bot in a Web Chat interface using HTML, you can use the Web Chat JavaScript library provided by Azure. Here's an example of how you can integrate the multilingual bot into your HTML code:

Include the Web Chat JavaScript library: Add the following script tag to your HTML file to include the Web Chat library.

html


<script src="https://cdn.botframework.com/botframework-webchat/latest/webchat.js"></script>

Create a container element for the Web Chat interface: Add a container element in your HTML where the Web Chat interface will be rendered. For example:

html

<div id="webchat"></div>

Initialize and configure the Web Chat instance: Add the following JavaScript code to initialize and configure the Web Chat instance. Make sure to replace YOUR_DIRECT_LINE_SECRET with your Azure Health Bot's Direct Line secret.

html

<script>
  const directLineSecret = 'YOUR_DIRECT_LINE_SECRET';
  const webChatContainer = document.getElementById('webchat');

  window.WebChat.renderWebChat(
    {
      directLine: window.WebChat.createDirectLine({ secret: directLineSecret }),
      language: 'en-US', // Set the default language here
    },
    webChatContainer
  );
</script>

Add language selection functionality: To enable language selection in the Web Chat interface, you can add a language dropdown menu or any other user interface element that allows users to switch between languages. When a user selects a language, you can update the language property in the renderWebChat configuration to reflect the selected language.

html


<select id="languageSelect" onchange="changeLanguage()">
  <option value="en-US">English</option>
  <option value="fr-FR">French</option>
  <option value="es-ES">Spanish</option>
  <!-- Add more language options as needed -->
</select>

<script>
  function changeLanguage() {
    const languageSelect = document.getElementById('languageSelect');
    const selectedLanguage = languageSelect.value;

    window.WebChat.renderWebChat(
      {
        directLine: window.WebChat.createDirectLine({ secret: directLineSecret }),
        language: selectedLanguage,
      },
      webChatContainer
    );
  }
</script>

In this example, the changeLanguage function is triggered when the user selects a language from the dropdown menu. It updates the language property in the Web Chat configuration and re-renders the Web Chat instance with the selected language.

By following these steps and customizing the HTML and JavaScript code to fit your specific needs, you can deploy a multilingual Azure Health Bot in a Web Chat interface on your website.
