COMPRESIóN DE VOZ MEDIANTE TéCNICAS DIGITALES PARA EL PROCESAMIENTO DE SE？ALES Y APLICACIóN DE FORMATOS DE COMPRESIóN DE IMáGENES

the present work shows the implementation of a model for compression of voice through the use of digital techniques for the signal processing and application of formats of compression of images. this work is based on the hypothesis that the compression of the voice under this scheme obtains a significant reduction of the amount of bytes and the consequent reduction of the necessary speed in bit/s for voice transmission. the philosophy of the model is centered in the conversion of frames of voice in compressed images, that later are transmitted through the channel, for later recovery, the frame of voice in the receiver, through a synthesis process. in order to obtain this, techniques in the dominion of time like in the frequency, are used by means of the application of iir digital filters (infinite impulse response), of fft (fast fourier transform), and of varied formats of image compression.
