Historical Context

In 1769, Hungarian nobleman Wolfgang Ritter von Kempelen embarked on the development of a mechanical speaking machine reportedly capable of producing a diverse range of respectable speech sounds. After two decades of great efforts, Kempelen published a book in 1791 detailing his observations on human speech production and his experiments with the speaking machine.[1]


First Experiment

Kempelen's initial attempt at speaking machine involved basic components mimicking the human vocal tract. Using a kitchen bellows for airflow, a bagpipe reed as the glottis, and a clarinet bell as the mouth, he managed to produce simple vowel sounds. However, the setup lacked the necessary components for constructing most consonants, such as nasals, plosives, and fricatives. Kempelen later shifted from a single-reed design to a multiple-reed approach in his second experiment.


Second Experiment

The second design resembled a musical organ console, operated by keys representing different letters. Utilizing a common bellows and various shaped pipes, he succeeded in producing several vowels and consonants, including /p/ and /m/. However, the sounds did not blend together in a natural way and vowels in particular came on rather explosively, thus adding a k-like sound. [2] Thus, kempelen began work on his thrid design.


Third experiment

The third approach, resembling the first design, featured enhancements including a rubber mouth, a simulated "throat" with nasal cavities, and additional mechanisms for articulating specific consonants. Kempelen's machine achieved speech in multiple languages, although it struggled with pitch variation and monotone delivery. Despite certain mispronunciations, listeners often overlooked errors, viewing the machine's resonance akin to that of a young child. Nonetheless, the third design marked significant progress from Kempelen's dedicated twenty years study of the vocal tract and speech production.

Impact

Von Kempelen's travail was not for naught and his impact far from nil.[3] While before Von Kempelen the larynx was considered central to speech production, his simple and successful demonstration drew the attention of 19th-century scientists to the vocal tract, the cavity between the glottis and the lips, as the main site of acoustic articulation. In 1791, after 20 years of hard labor, Von Kempelen published a book in which he described his observations on human speech production and his experiments with his speaking machine (Von Kempelen, 1791).Unfortunately, for the ultimate fate of his speaking machine the clever count conceived and demonstrated a chess-playing machine at precisely the same time he worked on his talking contraption. But the widely exhibited chess "automaton" was anything but automatic: it concealed a midget chess-master in its innards who communicated magnetically with the above-board chessmen. While the shifty machine (actually the hidden midget) is said to have beaten even Napoleon - no slouch at chess - the uncovered deception cost Von Kempelen his hardwon credibility. People simply assumed that his speaking machine, too, was just another fraud, merely conveying the speech sounds of a hidden human. His early forays into synthetic speech stimulated much research into the physiology of speech production and experimental phonetics.
