Open Settings → Preferences → Language I speak. The list has a search box.

Which one to pick

Detect as I speak: fine if you speak one language per note. It can mix up close languages, so pick yours if it guesses wrong.
One language (Hindi, Spanish, Japanese…): the note is written in that language's own script.
Hindi + English (Hinglish): for mixing Hindi and English. The note comes back entirely in Roman letters, the way you would type it in a chat: Kal subah mujhe bank jana hai, then the client meeting at 3 pm.
Language pairs (Tamil + English, Bengali + Hindi, and every other pair of Indian languages): the same as Hinglish, for your two languages. Everything comes back in Roman letters.

Language pairs need the latest version of the app.

Good to know

The setting applies to new recordings. Notes you already have keep their text, so record again after changing it.
A note that switches between three or more languages is not supported yet. See the known issue.
Names and brand words come out better once they are in your vocabulary.
