Hello,

 it seems that something is missing to get it working in "SpeecToTextButton". 

how to reproduce:

• tested in different browser(edge,vivaldi,ff), even in private mode https://www.telerik.com/blazor-ui/documentation/components/speechtotextbutton/integration
• load the page

1. click start recording
2. allow microphone access for the first time
3. nothing recorded(it stays max at 2secs in recording state), goto 1

it flickers for a while(at system taskbar, there is also indication of recording) but nothing is "recorded/transcribed".

Is there any additional setup at clientside?
