Thai dictation on a Mac: how to set it up, and where your voice is processed

By Ryleigh Newman · Published October 11, 2026

To dictate in Thai on a Mac, add Thai to Apple Dictation in System Settings, Keyboard, Dictation, by clicking Edit next to Languages. Or choose Thai in the Language picker on YapToText's AI Models page. Either way you speak Thai and Thai text lands at your cursor, in any app. The two differ in where the speech is processed, and for Thai Apple's own lists make that easy to check.

I built YapToText, a free dictation app that runs Whisper on your Mac, because my hands make typing difficult. I have not tested Thai dictation myself, so this page sticks to what each setting does and what Apple's own pages list, and makes no accuracy claims.

This app is completely free. You don't have to make an account. There are no subscriptions, no difficult downloads, and nothing is locked. Made for Apple silicon Macs. Source on GitHub.

What Apple lists for Thai

Apple's columns are from its macOS Feature Availability page, read October 11, 2026. Apple says Dictation is not available in all languages or regions and that features vary. YapToText from its own settings.

Set Apple Dictation to Thai

1. Choose Apple menu, System Settings, then Keyboard.
2. Go to Dictation and turn it on if it is off.
3. Click Edit next to Languages and select Thai, with your region where Apple offers more than one.
4. Start dictating. With more than one language set up, macOS shows the current language next to the cursor.
5. If another language is showing, click it, or press the Globe key, to switch to Thai.

Apple lists these for Dictation: Thai (Thailand).

Where Apple processes it

Apple's On-Device and Modeless Dictation list includes Thai (Thailand), with a note that it requires a download of speech models. So on a Mac with Apple silicon, Thai dictation can be processed on the Mac once that download is done. Keyboard settings says, under Dictation, whether your Mac is doing it on the device.

Punctuation

Apple's Auto-Punctuation list includes Thai (Thailand), so commas, periods and question marks can be added for you.

The auto punctuation page explains the setting.

Set YapToText to Thai

1. Open YapToText's AI Models page.
2. In Your defaults, open the Language picker and choose Thai.
3. Click into any text field, tap Right Command, speak Thai, and tap again.

Out of the box YapToText uses your Mac's system language, not Auto-detect, so if your Mac runs in English this is the step that makes it listen for Thai. The default model, Whisper Large v3 Turbo, is multilingual and is inside the App Store build. A model with (English) in its name hears English only. Everything runs on the Mac, so nothing you say in Thai is sent anywhere.

Two things that stay in English

YapToText's own screens are in English only, and its default spoken commands are English phrases such as question mark. You can add your own Thai phrases to any command on the Commands page, and keep the English ones beside them. The spoken punctuation help page shows how.

If Thai comes out wrong

• Check the picker. It starts on your Mac's system language, not Thai.
• Check the mode. A mode with its own language overrides the picker.
• Check the model. A model with (English) in its name hears English only.
• Read the raw transcript. History shows what Whisper heard before any cleanup.
• Two languages in one day. The bilingual dictation guide covers switching.

The language guide lists all 29 languages YapToText offers. Guides for other languages include Turkish, Vietnamese and Spanish.
