Which musical instrument sound most like a human voice?

double reed instruments, the Oboe, cor anglais, or the bassoon, because the reed acts most like the vocal chords. air pushes/rushes past the two parts and they vibrate creating the sound. then your mouth creates the Words, or in this case the keys create the different tones and notes. so out of all the instruments i'd say one of the double reed instruments because of the way they work and if they are played with Excelent tone quality they even sound like someone is singing through them.
