What gadget in Arkham Knight can imitate other characters' voices?

The Voice Synthesizer in Batman: Arkham Knight can imitate other characters’ voices. Batman uses it to reproduce recognizable vocal patterns and deceive enemies into responding as though a trusted or important character were speaking.

The gadget expands Arkham Knight’s emphasis on investigation and manipulation. Rather than simply opening doors with a code, Batman can use a copied voice to trigger verbal security systems or lure thugs into traps. The device is especially useful because enemy behavior depends on who they believe is addressing them.

Players commonly confuse the Voice Synthesizer with Batman’s earlier cryptographic tools. The Cryptographic Sequencer hacks electronic locks and control panels, while the Remote Hacking Device manipulates machinery from a distance. The Voice Synthesizer is specifically about vocal impersonation. In the game, examples include imitating Harley Quinn and the Arkham Knight, making the tool part puzzle-solving device and part psychological weapon.
