You can replace phrases by name, so you might say: “Replace 'I will be late' with 'I’m not going to make it.'" You can use this to uncheck a command you don’t want Voice Control to understand. Recognized Open Siri-related commands include Open Siri, Show Siri, Launch Siri and Switch to Siri, for example. You will also see that in each case there’s a checkbox beside each command.

Here you will see all the commands for different functions and can click on each one to see options for what it does. You should review all of Apple’s available commands in System Preferences>Accessibility>Voice Control – tap the Commands button.

You do not need to be online for Voice Control to work. Once you have enabled Voice Control, your Mac will listen for your commands. The icon shows you the current language and instructions to Wake Up or Sleep. Once you’ve set up Voice Control, you’ll find a new microphone icon on the lower right of your Desktop, just above the Trash. Click it to wake Voice Control, click again to put it back to sleep. (You may also need to select a microphone the internal one will be chosen by default.) How to reach Voice Control Voice Control will use the language you've configured for your Mac by default, but you can select another language if you are dictating in a different tongue. To turn it on, go to System Preferences>Accessibility>Voice Control and click the Enable Voice Control checkbox.

This makes Voice Control a much better dictation system than the Enhanced Dictation Apple provided in previous editions of Mac OS/macOS.
