AB  - To achieve recognition of silent speech, especially of the non-audible murmur this development raises
as a first step, the acquisition and transmission of vibration data from the sub vocal speech. Because of the
stochastic characteristics of an audio signal in the time domain this is treated and analyzed in the complex
frequency domain. To achieve the frequency analysis is implemented in this development a Fast Fourier
Transform (FFT). The data acquired and transformed with FFT are transmitted via a Wi-Fi network to a computer
for further analysis of signal and image processing through an application developed in C # language.
