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).
• Hidden Markov Models in Speech Synthesis (1980s-Now) Application of Hidden Markov Models in Multilingual Speech Synthesis： A Breakthrough in Text-to-Speech Systems.
• Advancements in Neural Network-Based TTS (2000s)
