Dictating Spanglish: Code-Switching Without Errors
If you think in two languages at once, you already know the pain: you start a sentence in English, drop in a Spanish word, and your dictation spits out nonsense. Here is how to dictate Spanglish on a Mac and switch languages mid-sentence without the garbled mess.
Key takeaways
- Single-language dictation forces every sound into one language, which is why Spanglish comes out wrong.
- A multilingual on-device model recognizes both English and Spanish without a mid-sentence switch.
- A custom dictionary fixes names, places and slang the model has never seen.
- On-device AI cleanup adds punctuation and removes filler while keeping your audio on your Mac.
Why regular Mac dictation mangles Spanglish
Bilingual speakers rarely talk in tidy, one-language blocks. You blend words, borrow terms, and switch languages inside a single thought. Linguists call this code-switching, and it is completely normal for millions of English and Spanish speakers. The problem is that most dictation tools were built around one language at a time.
Built-in Mac dictation asks you to pick a language before you speak. Once it is set to English, it assumes every sound you make is English and forces each word into the nearest English spelling. Say "quiero mandarte el reporte" in an English session and you may get a soup of unrelated English words. This is not a bug so much as a design choice: a single-language recognizer expects one language. When you want to know exactly what languages Mac dictation supports, you find the same catch every time, one active language per session.
Modern speech recognition has moved past that limit. Multilingual models are trained on dozens of languages at once, so they can identify Spanish and English sounds in the same breath. That is the foundation for dictating Spanglish cleanly.
What actually fixes it: multilingual models plus AI cleanup
Two things need to be true for Spanglish dictation to work. First, the underlying model has to genuinely know both languages, not just switch profiles. Models like Whisper and Parakeet are trained across many languages and handle mixed speech far better than a single-language engine. BlaBlaType runs these models entirely on your Mac, covering more than 90 languages, so you never toggle a setting halfway through a sentence.
Second, raw speech is messy in any language. You repeat words, add "um" and "este," and skip punctuation. On-device AI cleanup, powered by Apple Intelligence, reads the transcript and tidies it: it fixes punctuation, removes filler, and smooths grammar while preserving your meaning. For voice typing in general, this cleanup is what turns a rambling recording into text you can actually send. It matters even more in Spanglish, where a single misplaced accent changes a word.
How to set up Spanglish dictation on your Mac
The setup takes a few minutes and then works everywhere your cursor goes. Because dictation types system-wide, the same setup covers your notes, your browser and your chat apps. If you also want to reply to Slack faster by voice, this is the same flow.
Install a multilingual on-device app
Download BlaBlaType and let it fetch a local model. Recognition runs on your Mac, so your bilingual audio never leaves the device.
Pick a model that covers both languages
Choose a multilingual model rather than an English-only one. This is the single change that lets English and Spanish coexist in one sentence.
Add names and slang to your custom dictionary
Enter family names, place names and region-specific Spanglish terms. The app then spells them the same way every time instead of guessing.
Turn on AI cleanup and just talk
Enable on-device AI cleanup, press your shortcut, and speak naturally. Switch languages mid-sentence and let the cleanup handle punctuation and filler.
Most people speak around three to four times faster than they type, so once the setup is right, dictating Spanglish is quicker than switching keyboards or hunting for accented characters.

Handling names, slang and accents
The trickiest part of Spanglish is not the grammar, it is the vocabulary that no general model has memorized: your abuela's name, the neighborhood you grew up in, a brand only your group uses. This is where a custom dictionary earns its keep. Instead of hoping the model guesses "Yaritza" correctly, you add it once and it is locked in.
Custom AI prompts help too. You can tell the cleanup step to keep Spanish words in Spanish rather than translating them, or to preserve a casual tone for texts and a formal one for email. And when you genuinely want output in one language, the same app can translate as you speak, so a Spanish sentence lands in English. The point is control: you decide when to blend and when to convert.

A few concepts come up whenever people talk about mixed-language voice to text. Here is a quick glossary you can quote.
Mini glossary
- Code-switching
- Alternating between two languages within a single conversation or sentence, common and natural among bilingual English and Spanish speakers.
- Spanglish
- The everyday blend of English and Spanish, including borrowed words and mixed phrases, used by many bilingual communities.
- Multilingual model
- A speech recognition model trained on many languages at once, so it can recognize English and Spanish in the same audio without switching modes.
- On-device processing
- Speech recognition that runs entirely on your Mac's own hardware, so your audio and transcripts never get uploaded to a server.
- Custom dictionary
- A user-defined list of names, places and slang that tells the app how to spell terms it would otherwise get wrong.
Once these pieces are in place, dictating Spanglish stops feeling like a fight with your Mac. You speak the way you actually think, in two languages, and get clean text back. If mixed-language typing has ever slowed you down, this same on-device approach also helps anyone who finds typing tiring, including people who use voice to text for ADHD.

Frequently asked questions
Can Mac dictation handle Spanglish and code-switching?
Built-in Mac dictation locks to one language at a time, so it often garbles words when you switch between English and Spanish. A dictation app that runs a multilingual on-device model and adds AI cleanup, like BlaBlaType, handles mixed-language speech far better.
Why does dictation get Spanglish words wrong?
Most single-language recognizers expect one language and force every sound into it, so a Spanish word gets spelled as the nearest English word. Multilingual models trained on many languages recognize both, and a custom dictionary fixes names and slang the model has not seen.
Does BlaBlaType support both English and Spanish at once?
BlaBlaType uses on-device models that cover more than 90 languages, including English and Spanish, and can transcribe mixed speech without you switching a setting mid-sentence. Everything runs on your Mac, so your audio never leaves the device.
Is dictating Spanglish private on a Mac?
It is private when speech recognition runs entirely on-device. With BlaBlaType, your audio and transcripts never leave your Mac, so bilingual notes, messages and drafts stay on your machine with no cloud upload.
Can I add Spanish names and slang to dictation?
Yes. A custom dictionary lets you add names, places and slang so the app spells them correctly every time. This is the fastest way to stop dictation from mangling family names, brand names or region-specific Spanglish terms.
