Critical reception
Joe Tangari of Pitchfork gave the album an 8.3 out of 10, writing, "What might make In What Language? truly important ... is that it's focused intently on probing social issues in meaningful ways." Chris Nickson of AllMusic gave the album 4 out of 5 stars, commenting that "Written originally to be performed on-stage in a theatrical setting, it transfers well to a purely recorded medium, dense and demanding, but ultimately satisfying, inasmuch as it leaves the listener full of questions and less certain about the world." Lyn Horton of All About Jazz stated that "These composers have instituted a new paradigm for 21st century opera." Anastasia Tsioulcas of Billboard wrote, "With Iyer working as composer and Ladd as librettist, the two weave together elements of jazz, hip-hop and spoken-word art into a new, subversive kind of song cycle."
