Voice recognition is a technique that facilitates a natural and convenient human-machine interface using the voice recognition module. It extracts and analyses voice features of humans delivered to a machine or computer through the mic. The Voice recognition technique is classified into many types based on different criteria such as the scope of the users, the number of words used for recognition, and the naturalness of speaking. If the voice recognition level is more than 95%, then only voice recognition is practically used.
