In today’s world, you must have observed how even kids are fascinated by and driven toward using Alexa to play their favorite music or TV shows. It is astonishing to see those little humans working with one of the most recent technologies without knowing how it works. That is the specialty of this sub-type of artificial intelligence—conversational artificial intelligence. Conversational AI has enabled computers and software applications to listen, comprehend, and respond like humans. Try using Microsoft’s Cortana, Apple’s Siri, and Google’s Bard to understand what we’re saying. Or head over to OpenAI’s ChatGPT, the most recent and sensational conversational AI that knows it all (until 2021).

Before that, let’s get you brushed up on how these conversational AI models work. Furthermore, we will discuss what makes them talk and how they understand your responses.

What is Conversational AI?

Fundamentally, conversational AI is a kind of artificial intelligence (AI) technology that simulates human conversations. It enables computers and software applications to collaborate with humans in a human-like demeanor using spoken/written language. These systems can be implemented in various forms, such as chatbots, virtual assistants, voice-activated intelligent devices, and customer support systems.

How Does Conversational AI Work?

A conversational AI workflow is a collection of various processes. A typical conversation AI works in the following manner.

• Interactive User Interface: It has an interface using which the user inputs text. Alternatively, an ASR (Automatic Speech Recognition) system could record the user’s voice and convert it into text.
• Natural Language Processing: NLP technology is then used to extract the intent from the user input and transform it into structured data to be analyzed.
• Natural Language Understanding (NLU): NLU focuses on extracting the intent and context from the user’s input. It involves analyzing the information to determine the user’s goal or desired action.
• Natural Language Generation (NLG): Response generation using natural language generation (NLG). NLG is used to infer from the above process and generates responses to converse with humans.

Natural Language Understanding (NLU)

As the name suggests, natural language understanding (NLU) is a branch of AI that understands user input using computer software. It helps bridge the gap between the user’s language and the system’s ability to process and respond appropriately.

Importance of Accurate and Context-Aware Language Comprehension

As artificial intelligence advances, more and more companies are adopting AI-based technologies in their operations. Customer services and management is one area where AI adoption is increasing daily. Consequently, AI that can accurately analyze customers’ sentiments and language is facing an upward trend. This reduces the need for human professionals to interact with customers and spend numerous human hours trying to understand them.

NLU Techniques in Conversational AI Systems

NLU is a vital component of all conversational AI systems. To classify intent, extract entities, and understand contexts, NLU techniques often work in conjunction with machine learning. It uses supervised learning, named entity recognition, and deep learning.

• Supervised Learning: Generally, NLU models are trained using supervised machine learning with labeled training data. The training data consists of examples of user inputs and their corresponding intents and entities. Using this data, the NLU model learns to identify patterns and relationships between the input and desired output.
• Named Entity Recognition (NER): NER is a specific NLU technique to identify and classify named entities in text. It extracts entities like names, dates, organizations, or predefined categories.
• Deep Learning: Various NLU tasks utilize recurrent neural networks (RNNs) and transformers to capture more complex patterns in the input data. It helps in understanding intents and extracting entities effectively.

Intelligent Virtual Assistants (IVAs)

Have you interacted with Siri, Cortana, or Alexa? If yes, then you must be familiar with what virtual assistants are. Even if you haven’t, you must have at least heard about them. They are advanced conversational AI systems that simulate human-like interactions to assist users in various tasks and provide personalized assistance.

Role of Virtual Assistants in Providing Human-Like Interactions

Virtual assistants serve many purposes in today’s real world. Some of them are mentioned below.

• Context Awareness: These assistants maintain contextual understanding by considering user history, preferences, and other relevant information from prior interactions.
• Emotional Intelligence: Some advanced IVAs with emotional intelligence capabilities are being developed. You must have seen the famous movie “Her.” The film showcased how an AI can talk and respond to a human’s emotional needs.

Personalization and Customization Capabilities of Conversation AI

IVAs have opened more doors to personalized experiences. They can remember user preferences, adapt to user behavior, and provide tailored recommendations. The most widely used personal virtual assistant is Apple’s Siri. Apple’s direct consumer-facing virtual assistant can be personalized to user preferences regarding voice, accent, etc.

Omnichannel Integration

Another differentiator of conversational AI is omnichannel integration. Etymologically, an omnichannel approach seamlessly continues an ongoing conversation from one channel to another. And guess which technology has made it possible? It’s none other than Conversational AI.

Seamless Integration Across Multiple Channels

The conversational AI system maintains consistent behavior and responses across different channels with omnichannel integration. The context of ongoing conversations, user preferences, and previous interactions is shared seamlessly, allowing users to switch between channels.

Consistent User Experience and Data Synchronization

To offer an omnichannel experience, you must track all channels where customer interactions occur. This could be your website, application, Whatsapp, Facebook, or other platform. Integrating an AI-powered omnichannel chatbot can help connect all these channels. This will significantly enhance your brand presence on all digital media and enable large-scale data synchronization.

Contextual Understanding and Memory

Conversational AI systems offer highly accurate contextual understanding and retention. This allows them to maintain coherent responses for users.

Ability to Retain and Recall Previous Interactions

Conversational AI systems monitor the progress of going-on interactions while recalling data and context from prior interactions. The system can reference the stored information when a user refers to a previously mentioned entity or asks follow-up questions.

Contextual Awareness for Personalized Conversations

This is done by considering various factors like history, user queries, the context of ongoing conversations, and other related factors to solve disambiguate doubts. For example, if you ask a conversational AI, “Is it going to rain today?” the AI system understands that by “today,” you’re referring to the current date and are seeking weather information.

Intent Recognition and Dialogue Management

Another key differentiator of conversational AI is intent recognition and dialogue management.

Techniques for Accurately Identifying User Intent

The most prominently used technique for identifying user intent in NLU. As you must have read above, NLU enables these systems to analyze and identify more complex patterns and contexts in user input data. Supervised learning, recurrent neural networks, and NERs are used in NLU processes for the same.

Adaptive Dialogue Management for Dynamic Conversations

After determining the intent and context, the dialogue management component selects how the conversational AI system should respond. This entails choosing the best course of action in light of the conversation’s current state, the user’s intention, and the system’s capabilities. This is accomplished via predefined rules, state machines, and other techniques like reinforcement learning.

Machine Learning and AI Algorithms

Machine learning and artificial intelligence—are the two recent developments where algorithms have awakened and brought machines and computers to life. As key differentiators of conversational AI, both of them have contributed to computer-aided human interactions.
