Conversational AI & Voice Assistants – Building Natural and Intelligent Dialog Systems
Conversational AI & Voice Assistants is an advanced course that teaches how to design, develop, and deploy intelligent conversational systems that understand and respond to human language. The course combines principles of Natural Language Processing (NLP), speech recognition, and dialog management to create interactive AI experiences for both text and voice channels.
From virtual assistants like Siri, Alexa, and Google Assistant to enterprise-grade chatbots and voice-based customer support, conversational AI is reshaping how humans interact with technology. In this course, learners will explore frameworks such as Dialogflow, Rasa, IBM Watson Assistant, and Amazon Lex, along with speech-to-text and text-to-speech integration using APIs.
Through practical projects, you’ll gain end-to-end experience—building, training, and deploying conversational agents that can handle real-world conversations with naturalness and efficiency.

- What is Conversational AI?
It refers to AI systems that simulate human-like dialogue using NLP and speech recognition technologies. - What’s the difference between chatbots and voice assistants?
Chatbots interact through text, while voice assistants use both speech recognition and natural language understanding for verbal interaction. - What are intents and entities in NLP?
Intents represent user goals, and entities are key pieces of information extracted from input. - Which frameworks are commonly used for building chatbots?
Dialogflow, Rasa, Amazon Lex, and IBM Watson Assistant. - What is ASR and TTS in voice assistants?
ASR (Automatic Speech Recognition) converts speech to text; TTS (Text-to-Speech) converts text into spoken audio. - How do you handle context in conversational systems?
By storing session information, user states, and previous interactions to maintain continuity. - What is a fallback intent?
A predefined response triggered when the system cannot match user input to a known intent. - What are some evaluation metrics for chatbots?
Accuracy, intent recognition rate, F1 score, conversation completion, and user satisfaction. - What challenges exist in multilingual voice assistants?
Language nuances, pronunciation variations, translation accuracy, and maintaining contextual consistency. - Name real-world applications of Conversational AI.
Virtual assistants, customer support bots, healthcare triage systems, voice-controlled devices, and retail automation.
