The Vocoder


Much of today's pop music involves synthesized sounds. Many performersincluding Cher, Madonna, and the Beastie Boyshave tried to incorporate this distinct sound into their voices, by using a voice-coding device known as the Vocoder. Although the sound is very high- tech, the Vocoder was originally developed in the 1940s to improve telephone service. Inventor Homer Dudley of Bell Laboratories designed a way to break speech patterns into modules that could be transmitted over a narrow bandwidth. The Vocoder was also used during World War II to enhance poor trans-Atlantic messages between British Prime Minister Winston Churchill and U.S. President Franklin Roosevelt.

Citation styles gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).

Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.

Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, cannot guarantee each citation it generates. Therefore, it’s best to use citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
