source Wikipedia :Édouard-Léon Scott de Martinville is a French inventor born in 1817 in Paris where he died in 1879.Typographer and proofreader, he learned shorthand and, criticizing all existing methods, sought a mechanical means of recording speech. He invented the phonautograph, drawing curves on the paper representing sound waves; but one could not extract from these plots a text, as he had hoped, nor listen to the sound. In 2008, a team using the image from one of their recordings, made on April 9, 1860, could hear a voice singing In the moonlight. It is the earliest surviving trace of the sound of a human voice, seventeen years before Edison’s phonograph.
