Automating spoken dialogue management design using machine learning: An industry perspective

Tim Paek, Roberto Pieraccini
2008 Speech Communication  
In designing a spoken dialogue system, developers need to specify the actions a system should take in response to user speech input and the state of the environment based on observed or inferred events  ...  Researchers have recently pursued methods for automating the design of spoken dialogue management using machine learning techniques such as reinforcement learning.  ...  Commercial development and deployment The development of a commercial spoken dialogue system (SDS) is a complex process. Dialogue management is only a part of it, though arguably the most expensive.  ...
