Recently, human computer interaction system which involves speech recognition, synthesis etc. experiences tremendous growth, resulting in many applications being developed and commercialized. For instance, Microsoft recently launched the Microsoft Office that process the capability to pronounce (or read aloud)the input text using the speech synthesis engine. Indeed, speech synthesis is of important assisting human in various areas such as telephone speech, application in cars, public information systems, education assistance tools, email reading etc. Text to Speech (TTS) system is speech...

Image segmentation is one of the significant techniques in image processing to distinguish desired parts from its background for further analysis. It provides visual means for inspection of anatomical structure of human body, identification of disease, tracking of its development and input for surgical planning and simulation. Active contour models are regarded as promising and vigorously research model-based approach to computer assisted medical image analysis. However, it is not trivial to assess whether one segmentation algorithm performs more superior than the other. Therefore, a...

Unit selection speech synthesis creates speech by re-sequencing pre-recorded speech units selected from a speech database. The selection of the best unit sequence from the database is treated as a search problem in this book. The unit selection process is based on minimization of target cost and joins cost.This book introduces Simulated Annealing (SA) algorithm to solve unit selection problem in speech synthesis.Viterbi algorithm is commonly used to solve unit selection problem.However, viterbi algorithm consume large amount of computation when speech database is large.The advantage of using...
