In a review for AllMusic, Jonathan Widran wrote: "Two realities are abundantly clear from listening to this... she swings magnificently with great jazz company... and she's far more emotionally effective singing in her native Portuguese than in her heavily accented English."[3]
Christopher Loudon of Jazz Times stated that Purim and Moreira "hit a new high with Speak No Evil, arguably their most intriguing outing since their Return to Forever days of the early '70s."[4]
Writing for The Washington Post, Mike Joyce acknowledged that Purim is "not in prime form" on the album, but noted that it "has its rewards," and praised the "colorful support from her bandmates."[5]
In an article for All About Jazz, Javier AQ Ortiz called the album "a terrific work that provides a congenial listening experience, very well recorded and mixed, smartly arranged, and produced, with lots of good musical feelings."[6]
Leila Cobo of Billboard commented: "in this collection... there's a steady and exquisite sense of style and good taste."[7]
