Latest Patents

Hetherington holds a patent for "Concatenative speech synthesis using a finite-state transducer." This method involves a processing stage that selects segments based on their symbolic labeling through an efficient graph-based search. The search utilizes a finite-state transducer formalism, which incorporates a representation of concatenation constraints and costs. This approach limits the increase in computation required as the size of the source corpus grows. In practical applications, multiple alternative segment sequences are generated, and the best sequence is selected based on specific signal characteristics of the segments. He has 1 patent to his name.
