What is intenisty in praat9/20/2023 To conclude, more studies could be done to speech watermarking so as to make it more robust and more resistance to unauthorized detection. The method that uses intensity to determine the step size could have a different step size selection so as to improve the randomness of the step size selected. Instead of modifying the pitches itself, the intensity of the speech could be modified. Though the proposed methodologies were not as ideal as expected, further work and studies can be done on these techniques. With each method having its pros and cons, they can be further improved or part of the methodologies could be implemented in other techniques. The results of the proposed methodologies were not as ideal as expected. The proposed methodologies includes modifying pitches with step sizes based on intensity, using 4 step sizes and to allow user to enter the step size is based on mean of intensity. ![]() PRAAT is a free program that allows manipulation of pitches and intensity of speech file. They are also tested in additive noise environment for robustness. Peaks in intensity (dB) that are preceded and followed by dips in intensity are. The proposed methodologies implemented aims to achieve higher resistance to unauthorizedÄetection. A script written in the software program Praat (Boersma & Weenink. After which, methodologies were proposed and implemented. Put ProsodyPro.praat in the folder containing the sound files to be analyzed, and launch Praat Select Open Praat. Studies were also done on Quantization Index Modulation, as this was the technique employed in the paper. The algorithm was tested in additive noise environment. The paper by Coumou and Sharma was studied and implemented. Additionally, a minimal intensity (by default 40dB, c.f. (Report mean intensity of intervals): The intensity mean of the analysed intervals can be reported in the result file. Existing watermarking techniques are studied. averaging) the value from the neighbouring frames. The purpose of this project is to seek a methodology for speech watermarking that is more Which require authentication from clients, can increase their security to client by applying speech watermarking. Such as banks, telecommunications companies and hotels allow clients to apply and change their services over the phone. Industries, therefore, expand their servicing mode to include phones as a servicing method. In this digital age, mobile phones these days include more functions and have become a commonly used device for communication. ![]() Watermarking techniques have been widely employed in digital media, such as documents, Speech watermarking for mobile communicationsÄRNTU::Engineering::Computer science and engineering::Hardware::Input/output and data communications
