The opening line "Speak low when you speak love" is based on a line in William Shakespeare's comedy Much Ado About Nothing (1600), in which Don Pedro says "Speak low if you speak love."
"Speak Low" is featured in the 2014 German film Phoenix.
"Speak Low" is featured in the 1975 episode of Columbo, "Forgotten Lady", sung by John Payne, who calls it "a number from our new show".
In 1993, American singer, songwriter, actress and director Barbra Streisand released a cover of "Speak Low", taken from her twenty-sixth studio album, Back to Broadway (1993).
Critical reception
Larry Flick from Billboard wrote, "Tune from One Touch of Venus has a seductive, shuffling rhythm that blends well with Johnny Mandel's lush orchestration. As always, Streisand is in exemplary vocal form, and this track will prove a total joy to her devoted legion of fans."[2] Sam Wood from Philadelphia Inquirer complimented it as a "lusciously arranged ballad", and "a sinuous rhythm-and-blues reinterpretation" that's "probably Streisand's best chance for a radio hit" since "Memory".[3] Richard Harrington from The Washington Post felt that with Streisand singing low over Mandell's "supple orchestrations, it feels more like a pop song than a show standard."[4]
