Voice Controlled

Voice Command Based Robotics Workshop relates speech recognition & processing which will be actuated with the robot wirelessly for controlling its different actions. This voice recognition technology became more vital with the applications such as Siri (iPhone), Google Assistant and Amazon Echo. It is used in applications ranging from Aerospace, Home Automation and Robotics to Education, Language Translation and Care for disabled people. This workshop will let you build a Voice Controlled Robot that can be controlled through voice commands using android apps.


Can access computer system and make use of internet to perform search over Google.
