if already transcribing, stop speech recognizer

I cloned the code and adapted the Xaml and CS for the MainPage slightly, as shown below, to stop the speech recognition service once a certain voice command is triggered and then activate a phrase to be spoken via the Text-To-Speech service. I tried to produce a working example by adapting the sample code for Azure Cognitive Speech Service. 'Secret command') via Speech-To-Text, the user can hear the secret phrase back at full/normal volume through Text-To-Speech in a Xamarin Forms application. I'm ideally looking for a way to revert this so that once the appropriate voice command is recognised (i.e. The issue is that when you start recording audio for the Speech-To-Text service, the device's audio is set to recording mode (not sure what the technical term for this is called) and playback audio is set to a very low volume (as described in this SO question and here) and here. I am trying to create an app that takes user input in the form of a voice command (using Speech-To-Text) and outputs an audio announcement from the application (using Text-To-Speech).
