This book embodies the different fundamental issues and concerns associated with Speech science and technology. In Unit -1 ,an elaborate description on the different mechanisms associated with the speech production process of human being is given made. The parameterization of the different speech related entities and attributes are described in Unit -2 through unit-5. The different fundamental cues associated with Intonation and Annotation of speech sounds are brought to the readers through Unit-6. Through Unit -7, the different prosodic features associated with a language and finally displayed through speech are explained. Word boundary determination is another a global issue .Some of the frequently referred models in the texts and journals have been quoted and described in Unit-8. All the constraints in the design of any speech recognition and synthesis system , both in terms of mathematical modeling and hardware realization are broadly discussed in Unit -9 through Unit-12 . The different coding standards are put and discussed in Unit-12 so as to enable the readers to have an idea on the global trend ,twist and applicability of the speech technology , vis-à-vis speech sounds.
