Ventriloquism

This spell enables the magic-user to make it sound as if his or her voice — or someone's voice or similar sound—is issuing from someplace else, such as from another creature, a statue, from behind a door, down a passage, etc. 

The spell caster is able to make his or her voice sound as if a different creature were speaking or making the noise; of course, in a language known by him or her, or a sound which the caster can normally make. 

With respect to such voices and sounds, there is a 10% chance per point of Intelligence above 12 of the hearer that the ruse will be recognized. 

The material component of the spell is a small cone of parchment

Except as noted above, this spell is the same as the first level magic-user spell, ventriloquism (q.v.).
