A number of factors can lead to this issue, including faulty updates, outdated/corrupt audio drivers, and applications that don’t have access to the microphone. Below, we have listed different troubleshooting methods that are likely to help you get rid of this issue for good in no time.
Run the Speech Troubleshooter
Press Win + I to open Settings.
Under System, go to Troubleshoot.

Uninstall the Recent Update
