Editing Wolfgang von Kempelen's Speaking Machine (1769) (section)

== Key Innovations ==
The historic invention of Kempelen's Speaking Machine represents an early attempt and starting point for speech synthesis technology. Although this technology is considered outdated by today's standards and cannot directly influence the modern field of speech synthesis, it holds significant historical importance within the context of the 18th century. It marks the early exploration of speech synthesis, providing a foundation for the field's development.

==== 1. Mechanical simulation： ====
Kempelen's Speaking Machine garnered significant attention in its time because it was a mechanical device capable of mimicking human speech, which was considered a notable technological achievement in the 18th century. Although the technical principles of this machine significantly differ from modern speech synthesis technology, it served as an inspiration for subsequent research in speech synthesis and marked the early exploration of mechanical simulation of speech.<ref>Grassegger, Hans. “Von Kempelen and the Physiology of Speech Production,” n.d.[https://unipub.uni-graz.at/gls/content/titleinfo/1896583/full.pdf]</ref>

==== 2.Artificial Vocal Organ Simulation: ====
Kempelen's Speaking Machine included the simulation of human vocal cords, tongue, lips, and other sound-producing organs with mechanical components. While Kempelen was not the pioneer in this field, his Speaking Machine incorporated a more complex mechanical structure, which allowed for more precise simulations. Additionally, Kempelen's machine had the capability to control sound through mechanical devices, rather than merely passively imitating sounds. This was a significant technological achievement given the technological standards of the time.<ref>Trouvain, Jürgen, and Fabian Brackhane. “THE RELEVANCE TODAY OF WOLFGANG VON KEMPELEN’S ‘SPEAKING MACHINE,’” n.d.

==== 3.Multilingual support： ====
Multilingual support in Kempelen's Speaking Machine was a significant innovation with important historical implications. The machine possessed the capability to simulate different languages and dialects, which meant it could produce various sounds and pronunciations, not limited to a specific language. This was considered a technological achievement in the 18th century as it aimed to replicate the production of multiple speech sounds, thereby opening possibilities for research into different language communities and dialects.<ref>Liénard, Jean-Sylvain. “FROM SPEAKING MACHINES TO SPEECH SYNTHESIS,” n.d.[https://www.coli.uni-saarland.de/groups/BM/phonetics/icphs/ICPhS1991/12_ICPhS_1991_Vol_1/p12.1_018.pdf]</ref>
