Voice Command without Pressing a Button on iOS

Question

Currently, I am working on developing the iOS App that triggers an event upon voice command.

I saw a camera app, where a user says "start recording," then the camera starts to the recording mode.

This is an in-app voice control capability, so I am thinking it is different from SiriKit or SpeechRecognizer, which I have already implemented.

How would I achieve it?

My question is NOT the voice dictation where a user has to press a button to start dictation.

App needs to passively wait for a keyword, or intent, which is something like "myApp, start recording" or "myApp, stop recording", then the app starts/stop that event function accordingly.

Thanks.

There's an iOS 13 new feature called Voice Control that will allow you to reach your goal.

You can find useful information in the Customize Commands section where all the vocal commands are available (you can create a custom one as well):

For the example of the camera you mentioned, everything can be done vocally as follows: I showed the items names to understand the vocal commands I used but they can be hidden if you prefer (hide names).

Voice Control is a built-in feature you can use inside your apps as well.

The only thing to do as a developer is eventually adapting the accessibilityUserInputLabels properties if you need specific names to be displayed for some items in your apps.

If you're looking for a voice command without pressing a button on iOS, the Voice Control is THE perfect candidate.
