If your system is not detecting any input devices for voice input, there are a few things you can check:
- Check Microphone Settings: Ensure that your microphone is enabled in the settings. Go to Settings > Privacy & security > Microphone and make sure that microphone access is turned on for the apps you want to use.
- Check Device Connections: If your device does not have a built-in microphone, you may need to connect an external microphone or a headset with a microphone. Ensure that it is properly connected.
- Audio Device Settings: If you are using a headset, make sure that the audio input is set to the correct device. You can check this in Settings > System > Sound and ensure that the correct input device is selected.
- Troubleshoot Microphone: You can also run the Microphone Setup troubleshooter. Go to Settings > Time & Language > Speech, and select "Get Started" in the "Microphone" section to ensure that your microphone is configured correctly.
If these steps do not resolve the issue, there may be a hardware problem with the microphone itself or the system's audio drivers may need to be updated.
