A character can disguise his/her voice so that it sounds like that of another person if he/she makes a dice roll using his/her Acting (including mimicry specialism) + PE.
The difficulty depends on the nature of the mimicry being attempted, as follows:
| Nature of disguise | Difficulty |
| A type of voice (i.e. sounding the type rather than impersonating) | 3 |
| A specific individual's voice (i.e. impersonating) | 8 |
| The voice is quite different from the mimic's natural voice (e.g. very different accent, different gender) | +2 |
| There has been only limited time for the mimic to study the voice being imitated | +2 |
Successful mimicry gives a bonus of +2 on the mimicking character's dice rolls to pretend to be a different person. However, if the character fails the dice roll, there will be a penalty of -1 on the mimicking character's dice rolls to pretend to be a different person, per point by which the dice roll is failed.
A character can also use his vocal skills to throw his/her voice or speak without moving his/her lips so that the sounds appear to come from somewhere other than the character. To do this, the character must make a dice roll using his/her Acting (including mimicry specialism) + PE. There is a penalty of -3 on the dice roll per metre away the character is trying to throw his/her voice, and a penalty of -2 if the character is trying to speak in more than a muttering/whispering voice.
The dice roll result determines how hard it is for an onlooker to spot that the character is throwing his/her voice. The onlooker must make a dice roll using his/her Acting (including mimicry specialism) + PE, and obtain a result greater than or equal to that obtained by the ventriloquist to spot the ventriloquism.
