Emerging growth of information and communication technologies has influenced the research trends to focus on speech technologies. Pre-processing of speech signal serves various purposes in any speech processing application. It includes noise removal, endpoint detection, pre-emphasis, framing, windowing, echo canceling etc. Out of these, automatic(More)
This paper addresses the problem of improving the intelligibility of the synthesized speech in Tamil TTS synthesis system. The human speech is artificially generated by Speech synthesis. The normal language text will be automatically converted into speech using Text-to-speech (TTS) system. This paper deals with a corpus-driven Tamil TTS system based on the(More)
In recent years, speech processing has become an active research area in the field of signal processing due to the usage of automated systems for spoken language interface. In developed countries, the customer service with automated system in speech synthesis has been the recent trend. The existing automated speech synthesis systems have certain problems(More)
Image segmentation is rapidly applied in the field of image processing. In this paper a new method is suggested for implementing image segmentation. To overcome the problems of conventional threshold segmentation technique, an adaptive local threshold procedure is suggested. This method works well with images having non uniform intensity. The challenge of(More)
In this paper, we propose the development strategy of message transaction system in electronic business to business system with consideration of security. B2B must be designed to transfer electronic data between business and business in completely secured and reliable form. For the purpose of secured and reliable transaction of electronic data, we propose(More)
Ebstein's anomaly is a rare congenital heart disease characterized by downward displacement of the tricuspid valve, atrialization of right ventricle, enlarged right atrium with tricuspid regurgitation, or stenosis. It is often associated with atrial septal defect (ASD) or patent foramen ovale with right to left shunt. It has a varied clinical presentation(More)
Several prototypes and fully operational systems have been built based on different synthesis techniques. This paper describes the Text to Speech Synthesizer with prosody feature for generating natural human conversation. It also deals with forward parsing technique for sentiment analysis of the TTS system in an efficient way. The prosody features plays an(More)
