VAMP = Voice Amplification Modification and Projection
This highly sophisticated, tiny device has three functions:
[1] Modification: Allows the user to change his or her own voice into someone else’s.
[2] Amplification: Makes the user’s voice louder.
[3] Projection: Allows the user’s voice to travel greater distances and faster.
VAMP transponders can be embedded in other devices. Dash has one embedded in his Anti-Invisibility Goggles. It is manufactured by Mgadigadi Technologies.
Earring versions are available but they are expensive.
