You can use SFSpeechRecognizer (mirror) (requires macOS 10.15+): this is made for speech recognition.

Perform speech recognition on live or prerecorded audio, receive transcriptions, alternative interpretations, and confidence levels of the results.

Whereas as you have noted in the question NSSpeechRecognizer (mirror) indeed provides a “command and control” style of voice recognition system (the command phrases must be defined prior to listening, in contrast to a dictation system where the recognized text is unconstrained).

From https://developer.apple.com/videos/play/wwdc2019/256/ (mirror):

Another way is to directly use Mac Dictation, but as far as I know the only way is to rerdirect audio feeds, which isn't very neat, e.g. see http://www.showcasemarketing.com/ideablog/transcribe-mp3-audio-to-text-mac-os/ (mirror).
