For various reasons, Vent Haven has never done much outreach in Greater Cincinnati — either to attract greater attendance or to promote ventriloquism as a still-vital art form. But that is changing. This Saturday, at 2 p.m. and 7:30 p.m., it is presenting its first-ever family-friendly ventriloquism show, “Double Talk 2012,” in which four seasoned performers will present their live ventriloquism acts. $20. Notre Dame Academy Performing Arts Center, 1699 Hilton Drive, Park Hills, Ky. 859-341-0461, www.ventshow.com. The performance will serve as a fundraiser for the museum.
