[en] Web Accessibility Perspectives: Explore the Impact and Benefits for Everyone

hello,
I am developing a barrier-free progressive web app with HTML, CSS and Javascript. 
For this PWA I am looking for a way to program speech recognition that works on all operating systems. 

Can you help me?

accessible greetings

Markus Lemcke
