Use a voice changer app that supports live call audio
Install the app on your phone
Grant the required microphone and call permissions
Open the app before placing or answering the call
Select the voice effect you want
Make the call through the app if required
Use a Bluetooth headset or speaker if the app needs external audio routing
Test the voice effect with a short call first
Adjust pitch, tone, or speed settings if available
Use a VoIP app with built-in voice effects if your phone’s dialer does not support voice changing
Check local laws and consent rules before using voice-changing features
