Ventriloquism

The caster takes control of the target's body and voice, effectively turning them into a living puppet, should the target fail their wisdom saving throw. 

Whilst maintaining concentration, the caster can make the target move however they choose, and use the target's voice, in  whatever they wish. 

The caster although must be wary , for a still living target , will be somewhat aware while the spell is still in a effect, and may well know, that they were effected by the spell after it ends !!!
