change to English


Li'l Bull

Hi, native speakers of English!

Imagine you (a native speaker of English) are talking to someone in his mother tongue (French, Portuguese etc.). You know he speaks a little English, and now you would like to start to speak in English. What's the most natural way you can think of to tell him that now you're going to speak in English?

My try: "Let's change to English, shall we?" / "Let's speak in English now, shall we?"

Thank you in advance.
