Comparative Analysis of Speech Recognition based on Artificial Neural Network
People feels very comfortable with the speech so they want to interact with computers via their voice rather than hardware interfaces devices like keyboards and pointing devices. Speech is the easy and common medium to communicate with real system but unwanted voice signal comes during communication. In this paper, presents comparative analyses of the different methods used for better recognition. There are three types of categories of speech enhancement algorithms filtering based noise reduction, beam forming and Active Noise Cancellation (A.N.C) techniques.
