Hello Cyber-GH-Man,
Welcome to the
AudioDirector forum
If you are recording the voice over yourself, you'd need a microphone of some description. That mgiht simply be a webcam, headset, smart phone, audio recorder or video camera if you don't have a dedicated microphone. That is the first step - to record an audio file.
The next suggestion I'd follow is to record the "anonymous" dialogue using a character voice that is distinctly different from your own, if a little character acting is within your range of skills.
Once you have the audio file saved in an appropriate format, there are a number of adjustments that can be made in ADR that will further disguise the voice. I'm not sure which version you are using. That makes a difference. Please indicate the versdion you're using.
Adjusting pitch, timbre, speed would be the basic adjustments needed. There are also VST plug-ins that would be useful for your purposes.
