Show A Machine That Talks I B . . m A talking machlno that has created no llttlo sensation Is that Just produced pro-duced by Dr. II. Marago, a well known member of tho French academy of medicine. It Is an Interesting device, which reproduces with perfect accuracy accur-acy tho sounds of tho human voice, not. as In the case of tho phonograph, by merely repeating words spoken by a person, but by. a process which Is purely mechanical from start to finish, fin-ish, and In which no word Is spoken by any humnn being. Tho sounds aro produedd by a system of vibration. Attached to tho machlno aro n series of plaster heads, flvo In all, representing repre-senting tho flvo vowels, a, o, I, o, u. Thoy aro each a porfect modol of a person's mouth, fitted with pllnblo lips and perfect teeth. Air curronts set In motion by tho mnchluo aro mado to pass through tho dummy mouths, which are fitted with sirens. Through his invention, Dr. Marago has discovered that tho steam sirens used on board ships can be so con- H structed as to lmttato certain sounds. I Thus different phonetic syllables may B bo obtained which could bo tiRed to I form an International alphabet. By fl this ingenious contrivance attached to B this wonderful instrument it Is possl- I bio to see reflected in n tiny mirror I tho vocal chords of a singer. I By tho same device, ono can also I traco their action, nnd sco how, as I the noto gets higher, tho apertuVo between be-tween thorn becomes less and less, until whon tho top note Is reached It Is almost closed. As the force of air current expelled becomes stronger tho opening decreases In size. It increases as tho forco becomes less. Tho small-or small-or tho aperture tho groator tho' vibration.' vi-bration.' This is how human beings got tholr singing voices. "Thero Is no mystery about it," declares Dr. Marago. "It Is a purely mechanical process, based pn known laws of higher high-er mechnnlcs." Sketch. |
