Your voice, their command: The rise of AI-powered digital assistants

What is a digital assistant?

A digital assistant is a software-based application designed to help users perform tasks or services using natural language processing (NLP), speech recognition and often artificial intelligence (AI). It can interpret voice or text inputs, process them and respond accordingly — either by answering queries, automating routine tasks or providing personalised recommendations.

Does it work on artificial intelligence framework?

Yes, most modern digital assistants operate on an AI framework, particularly involving:

• Natural Language Processing (NLP) – to understand human language
• Machine Learning (ML) – to improve performance over time based on user interactions
• Voice recognition – to identify and process spoken commands
• Contextual awareness – to understand user preferences, past behaviours and situational context.

AI allows digital assistants to offer personalised, interactive and adaptive experiences.
