We all use our personal voice assistant which is pre-installed on our device when we are lazy, or sometimes when our hands pain. The personal voice assistant is an great example of hands free mode. Here is an review of one of the best personal voice assistant, Cortana. Cortana is a one of a kind personal voice assistant, which learns about you instead of the user learning about Cortana. Cortana learns about you while you interact with it. My experience with Cortana was an amazing experience. Cortana gives you suggestions based on your personal interest. Cortana is like an Virtual human who lives in an digital world. She even comes handy when you are bored. It was a great experience with Cortana and to be honest, Cortana will be your first virtual friend.
