One Voice is Boston University's multicultural, multi-genre a cappella group, originally founded as Kol Echad in 1995. As their name implies, they aim to deliver a musical experience that embraces a mix of styles and cultures within the ever-popular collegiate a cappella sound.

The group is a mainstay throughout the Northeast and often sings at cultural centers and universities, including Harvard, Brandeis, Rutgers, and Tufts. In 2022 and 2024, the group had the opportunity to compete at the ICCA Northeast Quarterfinals.
