Description

Introduction
As digital interactions evolve, users expect more intuitive, natural, and seamless experiences. Voicebots and multimodal interfaces combine speech, text, images, and gestures to enable smarter, more engaging human-AI communication. This course explores how to design and develop AI-powered systems that work across multiple channels, including voice, chat, visual UI, and even AR/VR interfaces. You’ll learn how to leverage NLP, speech recognition, and AI design principles to build applications that feel conversational and intelligent—on any device.

Prerequisites

• Familiarity with NLP and basic chatbot development

• Understanding of speech recognition and synthesis (e.g., Google Cloud Speech, Amazon Polly)

• Basic front-end/UI knowledge (optional but helpful)

• Python programming and REST APIs

• Interest in UX/UI and human-centered AI design
