How AI Learned to Speak Lots of Languages

AI can talk in many languages because it read books from all over the world.

5 min · Reviewed 2026

The big idea

AI doesn't just know English. It knows Spanish, French, Japanese, Arabic, and more — sometimes 100 languages. That's because it read writing from all over the world during training.

Some examples

Ask AI 'How do you say hello in Spanish?' and it answers 'Hola'.
AI can translate sentences between languages.
It works better in English because there's more English writing online.
Some smaller languages don't have as much training data, so AI is weaker at them.

Try it!

Pick a language you don't know. Ask an AI to teach you 5 simple words in that language — like 'hello', 'thank you', and 'cat'. Practice saying them out loud!

Practice this safely

Try this with a low-stakes example and a trusted adult nearby. The goal is to notice how AI talks about multilingual AI, not to let it make the decision for you.

Ask AI to explain multilingual AI in plain language, then underline anything that sounds uncertain or too broad.
Give it one detail from "How AI Learned to Speak Lots of Languages" and ask for two possible next steps plus one reason each step might be wrong.
Check translation against a trusted source, teacher, adult, expert, or original document before you use it.
