Enable Microphone Permissions for Adobe Fill & Sign

Granting microphone access directly in your Android system settings usually resolves inactive speech-to-text icons.

Android OS restricts apps from using the device microphone by default to protect your privacy. If Adobe Fill & Sign does not have explicit permission, the dictation icon will remain greyed out or unresponsive.

1
Open Device Settings

Navigate to your Samsung device's home screen or app drawer and tap the 'Settings' gear icon.

2
Locate the App

Scroll down and tap on 'Apps' to view all installed applications. Search for 'Adobe Fill & Sign' and select it.

3
Modify Permissions

Tap on 'Permissions', then select 'Microphone'. Change the setting to 'Allow only while using the app' to grant the necessary voice access.

Enable Microphone Permissions for Adobe Fill & Sign
Restart the App: After changing the permissions, completely close Adobe Fill & Sign and reopen it to ensure the new settings take effect.

Frequently Asked Questions

Why is the microphone icon visible but greyed out in my PDF app?

A greyed-out or unresponsive microphone icon typically means the application lacks the necessary system permissions to access your device's microphone, or voice input has been disabled in your active keyboard's settings.

Can I use speech-to-text on Android without an internet connection?

Most native Android voice typing services require an internet connection to process complex speech accurately. However, keyboards like Gboard allow you to download offline language packs for basic offline dictation.

How do I change my default keyboard on a Samsung phone to one that supports voice dictation?

Go to Settings > General management > Keyboard list and default. From there, you can choose a different default keyboard (such as Gboard or Samsung Keyboard) that fully supports voice typing functionality.

Does WPS Office mobile support voice typing for PDF documents?

Yes, WPS Office fully supports your device's native keyboard inputs. This means you can use Google Voice Typing or Samsung Voice Input seamlessly when filling out PDF forms or writing documents within the app.
