How to recognize voice commands in Swift

The following tutorial builds off our Speech Recognition tutorial which can be accessed using the link below.

We recommend that you clone our Open Source Swift Starter Project, checking out the tutorial/voice-loop branch and carrying out the steps below. The changes can be found on the tutorial/voice-commands branch.

Please note that if you do this you can jump to Step Three.

Setup Speech Recognition by following Apple's tutorial or following the tutorial below.

Follow the tutorial to make the Speech Recognition Algorithm endlessly loop.

Please note that we have updated the restartTimeInterval to 60 seconds.

Under the Models folder, create a new folder called Speech.

Within the Speech folder, create a new file called VoiceCommands.swift and paste in the code below.

Under the SpeechCoordinator folder, create a new file called SpeechCoordinator+Commands.swift and paste in the code below.

In SpeechCoordinator+Transcription.swift, update the recognition task closure to process the transcription that is received using the functionality created in Step Four.

Run your app and confirm that the commands are processed as expected, by checking the logs in the console.
