William Wong (@compulim) Is it possible to add a parameter for EndSilenceTimeout as well? I.e. the length of time that a SpeechRecognizer detects silence (after recognition results have been generated) and assumes speech input has ended (https://learn.microsoft.com/en-us/windows/apps/design/input/set-speech-recognition-timeouts).
