One of the changes in macOS Catalina was the removal of the “Enhanced Dictation” feature which allowed you to dictate offline in macOS Mojave.

This means that by default in Big Sur and Catalina, anything you dictate is sent to Apple for online translation by the Siri engine – which isn’t ideal if you’re dictating confidential documents or want to protect your privacy.

The good news is that you can still dictate offline in both Big Sur and Catalina but Apple has changed the way you activate it.

In macOS Catalina and Big Sur, the Dictation preferences look like the panel below – the Use Enhanced Dictation option has been removed.

In the latest versions of macOS, there’s also no apparent way of configuring useful formatting commands such as “new paragraph” and “left indent”.

Dictation in Big Sur and Catalina will also turn itself off after a few seconds of no voice input whereas in Mojave, it stays active until you turn it off yourself.

However the good news is that you can activate offline dictation in both Big Sur and Catalina yet still have formatting commands by going to System Preferences > Accessibility > Voice Control and checking the box Enable Voice Control.

This will then automatically download the language packs you need to dictate offline in Big Sur and Catalina.

The English language pack is around 422MB in size so you’ll need to make sure you have enough space on your mac hard drive first.

If you click on the Commands… button, you’ll also see all the different formatting voice commands possible too that used to be available in Enhanced Dictation in Mojave.

You can also activate and deactivate Voice Control by clicking on the floating Voice Control Microphone window or saying “Wake up” or “Go to sleep”.

What’s Voice Recognition Like in macOS Big Sur & Catalina?

The voice recognition feature in macOS has never been brilliant, although it’s not terrible either. The main problem is that it never learns to adapt or recognize your voice or vocabulary like professional dictation software.

The other issue is that whilst it uses Siri for US English which does a pretty good job of transcribing, it still uses the same inferior Enhanced Dictation engine for other languages (such as UK English) for which the results are much poorer.

One of the main problems is there’s quite a delay in non US English languages between the time you speak and the time it takes to transcribe.

The recognition accuracy is also far worse and our advice to users in the UK is to select US English as your language of choice as you’ll get far better results than selecting UK English.

In fact the US English dictation accuracy in the latest versions of macOS gives Dragon Dictate a run for it’s money although it’s not quite on the same level yet.

Voice Control of your Mac meanwhile works much better in both Big Sur and Catalina than dictating a document and if you just need Voice Recognition for this purpose, it’s faster and more accurate at controlling your Mac than previous versions of macOS.

Our advice is, if you haven’t upgraded to either macOS Big Sur or Catalina yet and rely on dictation for transcribing documents, it’s worth upgrading if you just need it for US English.

For all other languages, it’s best to hold off until Apple has Enabled Enhanced Dictation in the latest versions of macOS.

    Thanks for this mate, weird how Apple profess to protect users privacy but want access not only to what you dictate, but also your contacts and location in order ‘to provide a more accurate service’.

    If it looks like a duck, walks like a duck and sounds like a duck then it must be a duck.
