Speech and Language Processing: An Introduction to Natural Language Processing, Computational Linguistics, and Speech RecognitionFor undergraduate or advanced undergraduate courses in Classical Natural Language Processing, Statistical Natural Language Processing, Speech Recognition, Computational Linguistics, and Human Language Processing.
An explosion of Web-based language techniques, merging of distinct fields, availability of phone-based dialogue systems, and much more make this an exciting time in speech and language processing. The first of its kind to thoroughly cover language technology - at all levels and with all modern technologies - this text takes an empirical approach to the subject, based on applying statistical and other machine-learning algorithms to large corporations. The authors cover areas that traditionally are taught in different courses, to describe a unified vision of speech and language processing. Emphasis is on practical applications and scientific evaluation. An accompanying Website contains teaching materials for instructors, with pointers to language processing resources on the Web. The Second Edition offers a significant amount of new and extended material.

... unit selection synthesis . Like diphone synthesis , unit selec- tion synthesis is a kind of concatenative synthesis algorithm . The word unit means any stored piece of speech that is concatenated together to form an output . The intuition ...
... unit concatenates smoothly with its neighboring units , with no perceptible break Of course , in practice , we can't guarantee that there will be a unit that exactly meets our specifications , and we are unlikely to find a sequence of ...
... units ut and u1 + 1 to be concatenated were consecutive di- phones in the unit database ( i.e. , they followed each other in the original utterance ) , then we set the join cost to 0 : J ( ut , Ut + 1 ) = 0. This is an important feature of ...
