SCP-XXX: The Phantom Vocalist
Object Class: Euclid
Special Containment Procedures: SCP-XXX is to be contained within a standard humanoid containment cell, with additional measures put in place to prevent any instances of invisibility. The cell is to be equipped with a motion sensor and a sound detector, which will alert security personnel if SCP-XXX becomes invisible or mimics a voice.
SCP-XXX is to be fed three meals a day, consisting of non-perishable food items. All personnel are advised to avoid engaging in conversation with SCP-XXX, as it has been known to mimic voices and may attempt to deceive or manipulate individuals.
Description: SCP-XXX is a humanoid entity, standing at approximately 1.8 meters tall. SCP-XXX is able to turn invisible at will, and has shown the ability to mimic voices with uncanny accuracy. SCP-XXX's vocal mimicry is not limited to human voices, and it has been known to mimic the sounds of animals, machines, and even inanimate objects.
SCP-XXX's invisibility appears to be limited to its physical body, as it still casts a shadow and can be detected by motion sensors and other electronic devices. However, SCP-XXX is able to move silently and quickly, making it difficult to track and contain.
Addendum: SCP-XXX was discovered in [REDACTED], after reports of a "ghost" mimicking the voices of local residents and causing disturbances in the area. SCP-XXX was contained without incident, and has since been studied extensively by Foundation researchers.
