Abstract

The lack of facilities and infrastructures for students with special needs will hamper the learning process. In fact, this has been explained in the definition of inclusive education which is to accommodate students with special needs to comprehend the material in the class. The fact is that there are only public facilities such as the guiding block for the blind, and some interpreters in the class to explain the material. This situation is exacerbated by the limitations of an interpreter to explain scientific terms. Therefore, we need a technology that can help deaf people to comprehend the material in the classroom directly. The technology is speech recognizing device. This device enables to process input signals in the form of sound and is converted into text. This technology enables deaf people to comprehend material in the classroom without an interpreter. The research method is inferential statistics and observations. Observations were made by measuring 26 respondents speaking speed to obtain data using 3 different applications namely Speech Notes, Voice Notebooks, Speech to Text. Afterthat, the words obtained in the application are compared with the actual text to see the accuracy of each application. By using inferential statistics, the correlation test values obtained in the application of Voice Notebooks, Speech Notes, Speech to Text are 0.386,0.351, and 0.152, respectively. By using 5% significance level, we found that the most accurate speech recognizing application is Voice Notebook. Due to Voice Notebook application, we can support the special students in learning process in the class.

Abstract

The implementation of Lévy path integral generated by Lévy stochastic process on fractional Schrödinger equation has been investigated in the framework of fractional quantum mechanics. As the comparison, the implementation of Feynmann path integral generated by Wiener stochastic process on Schrödinger equation also has been investigated in the framework of standard quantum mechanics. There are two stochastic processes. There are Lévy stochastic and Wiener stochastic process. Both of them are able to produce fractal. In fractal’s concept, there is a value known as fractal dimension. The implementation of fractal dimension is the diffusion equation obtained by using Fokker Planck equation. In this paper, Lévy and Wiener fractal dimension have been obtained. There are for Lévy and 2 for Wiener/Brown fractal dimension. Fractional quantum mechanics is generalization of standard quantum mechanics. A fractional quantum mechanics state is represented by wave function from fractional Schrödinger equation. Fractional Schrödinger equation is obtained by using kernel of Lévy path integral generated by Lévy stochastic process. Otherwise, standard quantum mechanics state is represented by wave function from standard Schrödinger equation. Standard Schrödinger equation is obtained by using kernel of Feynmann path integral generated by Wiener/Brown stochastic process. Both Lévy and Feynmann Kernel have been investigated and the outputs are the Fourier Integral momentum phase of those kernels. We find that the forms of those kernels have similiraty. Therefore, we obtain Schrödinger equation from Lévy and Feynmann Kernel and also the comparison of Lévy energy in fractional quantum mechanics and particle energy in standard quantum mechanics.
