Disguised Voice

Check Modifier Voice is not your own, but is not that of a +5 distinct individual Voice is that of a different gender –2 Voice is that of a different race –2 Voice is that of a different age category –2 Voice is that of a different size category –5 Also, the creature making the Perception check gains a bonus based on its familiarity with specific voices, just as if it were confronted with a normal disguise (Core Rulebook 95). This ability is a language-dependent effect, meaning that if a creature cannot hear or understand what the infiltrator is saying, the ruse fails. Magic items, feats, and traits that affect disguises do not affect this special Disguise check.
At 8th level, the infiltrator gains the effects of his master of disguise class feature on this special use of the Disguise skill (no penalty for a voice of a different gender, race, or age category, and only a –3 penalty for a different size category). This ability replaces poison lore.
