The natural‚ intelligible synthetic voices in the expanding field of speech technology had a lot of demand [4]. Speech was the natural form of human communication. Automatic speech signal generation on computers is commonly called speech synthesis. Speech synthesis was the artificial production of human speech [2]. Speech

October 17 & October 24‚ 2012 How is Aspirin Made? This lab is about synthesizing aspirin using a hotplate to heat the reaction. It involved vacuum filtration‚ recrystallization‚ and comparing the properties of aspirin with salicylic aspirin. The first thing we did in this lab was make a hot-water bath by putting a beaker with water on a hot plate. After measuring out 2.1 grams of salicylic acid and 3 ml of acetic anhydride‚ we mixed the two together‚ along with 3 drops of sulfuric acid. We

Synthesis and Isolation of Expectorant Guaifenesin By: Ben DuBose Dr. Cossey 3361L Abstract The purpose of this experiment was to isolate and synthesize Guaifenesin. Isolation was performed with the use of two Guai-Aid Tablets‚ each of which contained 400mg of pure Guaifenesin. Reflux‚ a technique used to heat a mixture without evaporating the solution‚ was used to synthesize Guaifenesin through a Williamson Ether Synthesis reaction with an SN2 mechanism. Introduction

ABSTRACT In this paper we address the issue of pronunciation model- ing for conversational speech synthesis. We experiment with two different HMM topologies (fully connected state model and forward connected state model) for sub-phonetic model- ing to capture the deletion and insertion of sub-phonetic states during speech production process. We show that the experi- mented HMM topologies have higher log likelihood than the traditional 5-state sequential model. We also study the first and

Voice browsers allow people to access the Web using speech synthesis‚ pre-recorded audio‚ and speech recognition. This can be supplemented by keypads and small displays. Voice may also be offered as an adjunct to conventional desktop browsers with high resolution graphical displays‚ providing an accessible alternative

specific enantiomers of molecules. If the chirality of the molecules is incorrect‚ they may not be utilized or may even hurt the organism. For this reason a method to create chiral molecules is very important and for this reason we study asymmetric synthesis. One method in which a chiral epoxide can be synthesized is through the use of a Jacobsen-type catalyst. In order to synthesize Jacobsen’s catalyst‚ Jacobsen’s ligand must be created first which requires the use of 3‚5-di-tert-butyl-salicylaldehyde

IS AN ORGANIC COMPOUND? An organic compound is any member of a large class of gaseous‚ liquid‚ or solid chemical compounds whose molecules contain carbon. Organic chemistry is the science concerned with all aspects of organic compounds. Organic synthesis is the methodology of their preparation.

The study process: The study process is initialized by going through different web sites and blogs in order to know about the Text-To-Speech methodology. We have tried to understand the purpose of voice synthesis. Whatever we have discovered from the Internet is described below.
