For a detailed understanding of the voice recognition system, consider the block diagram, shown in figure1.The voice input takes in the spoken words. The A/D converter then decodes it. The modeling can then be done in two ways, as described below. Fig. 1: General block diagram of speech recognition system Acoustic Model.

Figure 1 shows the basic block diagram of a speech recognition system. As can be seen from Figure 1 , acoustic models are required to analyze the speech feature vectors for their acoustic content.. Basic block diagram of a speech recognition system is shown in Fig. a) In speech recognition system using microphone one can input speech or voice. The analog speech signal is converted to digital speech signal by speech digitizer. Such digital signal is called digitized speech. b) The digitized speech is processed by DSP system. The.
