One of the things I love about Copilot Studio is that it will let me build agents that can converse in multiple languages. Even without enabling multi-language support, if I simply enable my agent to use its own general knowledge, it will automatically understand and comply when a user types a message in a different language or asks for a response in a specific language.

Try it out – go to any of your agents and ask it a question in another language. In my screenshots, I'm working with an agent that was created in English (en-us) and no other language has been enabled. In the middle of the conversation, I asked a question in Turkish (with a typo), and later I asked it to respond to my English question in Arabic. You'll be pleasantly surprised that it does so even if the knowledge source(s) it uses to answer the question are entirely in English.

This also works for questions that your Agent has to answer with its own general knowledge. Speaking of general knowledge, the main requirement here is that you enable the agent to use general knowledge.

Of course, not every language is supported at this time. As of January 2025, Copilot Studio supports 23 languages in various capacities (27 if you count the multiple localizations of English, French and Spanish).

Most recently added was support for Arabic (ar-SA) as the primary language for Agents (in preview), as well as for Generative answers and Voice support.

The table below shows the full list of supported languages at the time of this writing. You will notice that Generative Orchestration (with Descriptions) is only available in English (US) at this time. Also, not all of the 27 languages are supported as the language of Authoring canvas at this time.
