Important

Power Virtual Agents capabilities and features are now part of Microsoft Copilot Studio following significant investments in generative AI and enhanced integrations across Microsoft Copilot.

Some articles and screenshots might refer to Power Virtual Agents while we update documentation and training content.

You can configure routing rules to route voice calls to appropriate agents based on the language that your customer has selected. A multilingual contact center helps you serve global customers who want to interact with your contact center in the language of their choice. You can also set up bots as the first contact who can handle such requests.

Use Bot Framework Composer in Copilot Studio to set up a bot for a multilingual contact center.

The process for setting up the multilingual bot in Copilot Studio is as follows:

  1. Create a bot in Copilot Studio.

  2. Create a topic in Bot Framework Composer.

  3. Configure the greeting topic in Copilot Studio.

  4. Configure the transfer to agent node by using the escalate topic.

  5. Configure workstreams and queues.

  6. Verify the multilingual bot.

Note

The new multilingual chatbots aren't currently supported in Omnichannel for Customer Service.

Prerequisites

  • You must install Bot Framework Composer locally on the computer that you'll use to configure the multilingual bot.
  • Your bot must be registered in the Azure app registration page. Note the application ID. More information: Create an app registration

Create a bot in Copilot Studio

You'll create a bot in Copilot Studio by selecting the environment in which Omnichannel for Customer Service is configured. For detailed instructions, go to Create a bot.

For example, you can create a bot with the following details:

  • Name: A descriptive name for the bot, such as Greeter bot.
  • Language: The primary language for the bot, such as English (US).
  • Environment: The environment where Omnichannel for Customer Service is configured, such as contoso-printers.

Create a topic in Bot Framework Composer

  1. In Copilot Studio, for the bot that you created, select Topics in the site map, and then in the Topics pane, select the dropdown arrow for New topic. A message appears stating that the application is trying to open Bot Framework Composer. For more information on how to navigate the Bot Framework Composer, see: Tutorial: Create a weather bot with composer.

  2. Select Open, and on the Import your bot to new project dialog that appears, enter the following details:

    • Name: A name for the project, such as Multilingual bot.
    • Location: Select a folder on the computer.

  3. In Bot Framework Composer, select More commands (...), select Add a dialog, and enter the following details:

    • Name: A name such as PVA greeter dialog.
