Yeah, I suppose I should have formulated that more clearly. The API offers cloud speech recognition for a set of languages, and on-device speech recognition for a subset of these.

It's not a static set, because (1) availability tends to expand over time and (2) when you start using a new language, the on-device model needs to be downloaded first.
So what you need to do is create a SFSpeechRecognizer and then test the supportsOnDeviceRecognition property. If that is set, you can set requiresOnDeviceRecognition on the SFSpeechRecognitionRequest.
