Speech Synthesis
- Early attempts at mechanical synthesis: Christian Kratzenstein (1779), Wolfgang van Kempelen ('Acoustic-Mechanical Speech Machine', 1791), Charles Wheatstone (1840s).
- The Bell Telephone Laboratory's Voder (1930s).
- Neural network-based models(1795-20s)
- Hidden Markov Models in Speech Synthesis (1980s-Now) Application of Hidden Markov Models in Multilingual Speech Synthesis: A Breakthrough in Text-to-Speech Systems.
