Editing Voder (section)

== Key Innovations ==
The Voder was among the first devices to allow manual control of speech synthesis. It was a pioneer in electronic sound generation, breaking down human speech into its fundamental acoustic components and reproducing these patterns electronically. This was a significant advancement in the early stages of electronic speech synthesis. Moreover, Voder was the first successful attempt at recreating an important physiological characteristic of the human voice – the ability to create voiced and unvoiced sounds<ref>Dudley, H., Riesz, R. R., & Watkins, S. S. (1939). A synthetic speaker. ''Journal of the Franklin Institute'', ''227''(6), 739-764.</ref>.

To improve the operator's performance, the Voder had a recording and playback feature that allowed operators to objectively analyze their areas of improvement. This feature is similar to modern-day contact centers that use call recording and analysis to improve agent performance.

As a matter of fact, the abilities of Voder went beyond human voice, as it could also produce non-speech sounds such as musical tones and sound effects<ref>Diesterhöft, S. (2003).
