DSP Appication: IEEE Paper and Patent reviwe

For this lab session, we were divided into groups and had to implement a practical application of signal processing.

Team : Parth Panchal,Soumyaa Passari ,Pranali Patil,Purvika Patil and Suma Salian
Individual experiment was to review one IEEE paper and one patent on Speech Recognition.
