SV111 (alternately pronounced one-one-one or one-eleven) was a Super-Voc programmed with all supervisory functions in industrial, commercial and civil functions. As part of the newer generation of Vocs, it had Tula Chenka's voice.
SV111 was used as a demonstration model. It was summoned by Tula as a demonstration for the Eighth Doctor and assisted Galla Posca during the robot attacks, sending out a self-destruct command to all of the robots in the complex. (AUDIO: Escape from Kaldor)
