Understanding Virtual Assistant (AI Assistant)

A virtual assistant or AI assistant is an intelligent computer system that is always available to perform a task or do a service for a person, and the interaction process is carried out through text or voice. These tasks involve responding to questions, coordinating the calendar, smart control of home devices, or web searches to perform a specific task online. Virtual assistants are AI-based systems that decipher and answer the inputs, usually in the users’ natural language, and may adapt to the task through enhanced performances based on new information gathered in the process.

Examples include Siri available on Apple iOS devices, Google Assistant on Android devices, Alexa by Amazon, and Cortana by Microsoft, among others.

Key Functionalities of Virtual Assistants
