However, the first machine to actually produce words and short sentences was the “acoustic-mechanical speech machine” invented by Wolfgang von Kempelen. Kratzenstein’s background in physiology greatly helped with his understanding of how the movement of air through the vocal folds produce sound which made him successful in producing a speech synthesis.
DID YOU KNOW?ĭid you know that the first machine to produce a human sound was created in 1779? Christian Gottlieb Kratzenstein made a model of the human vocal tract named “vowel organ." He used resonance tubes connected to organ pipes with free reeds to produce five long vowel sounds. Conversely, a speech-to-text system does the opposite, with speech recognition as its main function.
It is part of natural language generation in natural language processing, wherein a machine is programmed to synthesize speech that is similar to the natural voices of humans in pitch, tone, and duration. Text-to-Speech systems, often abbreviated as TTS, is a system that converts phonetic and orthographic transcriptions into artificial speech.
