CHAPTER I 1.0 INTRODUCTION Speech synthesis is the artificial production of human speech. A computer system used for this purpose is called a speech synthesizer‚ and can be implemented in software or hardware. A text-to-speech (TTS) system converts normal language text into speech; other systems render symbolic linguistic representations like phonetic transcriptions into speech. The ultimate goal of text-to-speech synthesis is to convert ordinary orthographic text into an acoustic signal that

Microcontroller and Sensors Based Gesture Vocalizer Abstract: - Gesture Vocalizer is a large scale multi-microcontroller based system being designed to facilitate the Communication among the dumb‚ deaf and blind communities and their communication with the normal people. This system can be dynamically reconfigured to work as a “smart device”. In this paper‚ microcontroller and sensors based gesture vocalizer is presented. Gesture vocalizer discussed is basically a data glove and a microcontroller

Introduction Methyl Salicylate has been used for a long time for its pleasant odour and flavour. The objective of this experiment was to carry an organic synthesis; the preparation of salicylic acid from methyl salicylate. To do an organic synthesis‚ it is needed to chemically modify the molecules of another compound to end up with the desire compound. Methyl salicylate is the major constituent of wintergreen oil‚ which is why it was used in this experiment as the starting material. The new technique

algorithm is proposed for removing large objects from digital images. The challenge is to fill in the hole that is left behind in a visually plausible way. In the past‚ this problem has been addressed by two classes of algorithms: (i) “texture synthesis” algorithms for generating large image regions from sample textures‚ and (ii) “inpainting” techniques for filling in small image gaps. The former work well for “textures” – repeating twodimensional patterns with some stochasticity; the latter focus

I. INTRODUCTION Synthesis Acetylsalicylic acid is an acetyl derivative of salicylic acid which appears as a white and crystalline and a weakly acidic substance with a melting point of 135°C and is also known to be aspirin. It is one of the most widely used drugs that can lower fever and is used as a painkiller. According to (Escobel‚ 2011)‚ Aspirin is synthesized through the reaction of salicylic acid with acetyl anhydride that causes a chemical reaction that turns salicylic acid’s hydroxyl group

II. Synthesis This activity helps me to understand myself better by knowing what people think of me. It aims to foster self-awareness and self-improvement. I found out that my family thinks that I am a responsible person in terms of sense of responsibility. But my brother thinks I’m immature. In terms of duties at home‚ my mother and father understand that I don’t perform my duties because I’m busy with my studies. My sister thinks it too but she justified that I perform when I’m not busy. When
