One language, many voices
You speak differently to your boss, your best friend, and your child's principal. That is normal. "Code-switching" is what we call moving between these voices. AI can practice all three with you in one session.
Three registers in English
Compare the options
| Register | Where you use it | Example sentence |
|---|---|---|
| Formal | Job interview, court, medical visit | "I am writing to inquire about the position." |
| Neutral | Most workplaces, school, polite stranger chat | "I'm interested in this job — can we talk?" |
| Casual | Friends, family, group chats | "Yo, you hiring? I'm down." |
Watch the cues
- First-name greeting? — likely casual
- Sir or Madam, Dr., Mr., Ms.? — likely formal
- Slang or jokes from them? — match casual
- Suit and tie? — formal
- Group chat with emojis? — casual
Words to know
- code-switching — moving between language styles
- register — how formal or casual your language is
- cue — a hint about what to do
- neutral — in the middle, neither very formal nor casual
- context — the situation around your speaking
The big idea: real fluency is not just one perfect English voice. It is many voices, picked for the moment.
