Enable Mic: Slide the switch to turn the microphone ON. (Grant audio recording permissions if prompted).
Speak: Begin your speech using your phone's microphone.
Disable Mic: When finished, slide the switch back to turn the microphone OFF.
2. Android Phone + Earpiece (with Mic) + Bluetooth Speaker
Connect Input: Plug in or connect your earpiece (ensure it has a built-in mic) to your phone first.

⚙️ Background Usage & Interruptions
Background Play: You can press the Home button to use other applications while the microphone is active. You can easily pause or resume the app using the notification panel.

The app is not performing anything more than extending your voice to an extended speaker. No data microphone is stored shared with others users. The use of the app to extend people's voices without their knowledge is at the user's risk.
The app access audio input only when requested and provides a notification showing that the microphone is on. All input from the mic will be sent to the current output device(speaker) connected.
We are not responsible for the abuse of the app.
