Active Voice Building, Commercial building in downtown Seattle, United States.

The Active Voice Building is a reinforced concrete and steel-frame office building on the southwest corner of 6th Avenue and Lenora Street in Seattle. Its exterior is clad in solar bronze window panels, and it abuts the Westin Building to the south, connecting directly to the Westin's meet-me rooms and colocation facilities.

Built in 1962 for the Internal Revenue Service, the building was long known as the United Airlines Building. It was renamed the Active Voice Building in 2005 after Active Voice, LLC, a subsidiary of NEC Unified Solutions, became the anchor tenant with 42,600 square feet on three floors. Renovations took place in 1975 and 2001.

The ground floor houses Dimitriou's Jazz Alley, a jazz club, and a day spa. The club occupies the base of the office tower at 6th Avenue and Lenora Street, so live jazz and spa treatments sit directly beneath the building's office floors.
