If you ask me which is my current favorite device then I can say its Amazon Echo. Alexa is our best entertainer and infotainer at my home. From my mom to sister everyone using it for a heterogeneous purpose.Like playing Songs to booking UBER ride. I feel this bi-directional audio technology really creating an impact on our daily lifestyle in a positive way. In 90’s radio was popular but it was replaced with video because of its unidirectional nature. Voice is really getting mature using AI assistant like Amazon echo & Google home. I love the way Amazon created its Amazon echo skills [especially flash briefing skills ]marketplace for a developer to build some amazing voice-based applications.
