HMM-based speech synthesis with various degrees of articulation: A perceptual study

Benjamin Picart, Thomas Drugman, Thierry Dutoit
2014 Neurocomputing  
HMM-based speech synthesis is very convenient for creating a synthesizer whose speaker characteristics and speaking styles can be easily modified.  ...  This can be obtained by adapting a source speaker's model to a target speaker's model, using intra-speaker voice adaptation techniques.  ...  Hypo/hyperarticulated speech synthesis has many applications: expressive voice conversion (e.g. for embedded systems and video games), "reading speed" control for visually impaired people (i.e. fast speech  ...

The roles of language processing in a spoken language interface

L. Hirschman
1995 Proceedings of the National Academy of Sciences of the United States of America  
This kind of interaction requires the system to have both input and output capabilities, that is, for speech, both recognition and synthesis, and for language, both understanding and generation.  ...  This is a serious problem-it is clearly desirable and useful to have a static set of data, with answers, so that experiments can be run repeatedly, either for optimization purposes or simply to experiment  ...
