Working of Open Assistant

Open Assistant mainly consists of three parts boot mind, root mind, and user minds. The boot mind and root mind are hardcoded with retrieval-based natural language processing to enable offline operations with high accuracy and increased speed.

Boot mind gets activated when you press the power button and it initializes the root mind when the trigger word is spoken. The root mind helps the system to respond to a basic set of voice commands. The user mind is the most advanced component which has the ability to learn and behave in a specific way.
