How to Dictate in Multiple Languages on a Mac

If you write in more than one language, dictation should keep up with you. This guide covers three ways to dictate in multiple languages on a Mac: switching per session, mixing languages mid-sentence, and translating as you speak, all while keeping your voice on-device.

Three ways to dictate in more than one language

There are three distinct situations people mean when they ask how to dictate in multiple languages on a Mac, and each has a different best answer. Getting the right one saves a lot of frustration with voice to text.

• Switching languages between sessions. You write an email in Spanish, then a note in English. You only need one language at a time, but you need to change it easily.
• Mixing languages in one flow. You speak French but drop in English brand names, or you code-switch naturally between two languages in the same paragraph.
• Translating as you speak. You think and talk in your first language, but the text needs to come out in another.

Apple's built-in dictation mac feature covers the first case, but it gets awkward for the other two. That is where a dedicated speech to text app changes the experience.

Option 1: Switch languages with built-in Mac dictation

macOS ships with a dictation feature you can enable in System Settings under Keyboard. You can add several languages there, then pick the active one before you start speaking. It works, and it is free, but it transcribes only the single selected language at a time. Every time you change languages you interrupt your flow to open settings or use the language menu. For a deeper look at coverage, see our breakdown of what languages Mac dictation supports.

Option 2: Let an app detect the language for you

The friction of manual switching disappears when the app detects the spoken language for you. BlaBlaType runs local speech models that recognize 90+ languages, so you can start a sentence in one language and the app transcribes it correctly without you touching a menu. Because the recognition happens on your Mac using local Whisper and Parakeet models, this works offline and nothing is uploaded. If you are weighing local versus cloud approaches, our guide on offline vs cloud dictation on Mac explains the trade-offs.

This matters most when you dictate into tools that expect precise input, like a code editor or an AI coding assistant such as Cursor, where you might narrate a prompt in one language and paste a variable name in another. On-device AI cleanup then removes filler words and fixes punctuation so the result reads cleanly.

Option 3: Translate as you speak

The third case is the most powerful. With translate-as-you-speak, you talk in your most comfortable language and the text appears in another. BlaBlaType offers optional translation across its 90+ supported languages, so a Spanish speaker can dictate a message and send it in English. Like everything else, translation runs on-device, so your audio and transcript never leave your Mac. Here is what that transformation looks like in practice.

The filler words and false starts are gone, the punctuation is correct, and the language has switched. That combination of detection, cleanup and translation is hard to get from built-in tools alone.

Multilingual dictation options compared

The pattern is clear: built-in dictation is fine for one language at a time, cloud apps add features but upload your voice, and only an on-device app gives you detection, mixing and translation without the privacy cost. For the wider field, see our roundup of the best dictation software for Mac.

Make any language spell names correctly

Multilingual work throws a lot of proper nouns at a dictation engine: colleague names, brand terms, cities, technical jargon. A custom dictionary fixes this. You register the words once and the app spells them right regardless of the language you are speaking. This is one of the most useful habits for multilingual users, and we cover the setup in detail in our guide on how to add custom words to your Mac dictation. Combined with custom AI prompts, you can also shape tone per language, for example keeping business Japanese formal while letting casual English stay relaxed.

Why on-device matters for multilingual users

If you dictate across languages, you are often handling sensitive or personal content: messages to family abroad, client work under an NDA, drafts you would rather not send to a server. On-device dictation keeps all of it on your Mac. That is a privacy guarantee cloud tools cannot match, and it is worth understanding before you commit to a workflow.
