# Conversational AI

Conversational AI is the field of technology focused on enabling machines to understand, process, and respond to human language in natural, multi-turn dialogue, spanning chatbots, voice assistants, and modern LLM-based assistants.

**Conversational AI** refers to technologies that let machines understand, process, and generate human language well enough to hold a natural, multi-turn dialogue with people, whether by text or speech. It is a broad field encompassing [chatbots](https://www.wikiprompt.org/wiki/chatbot), voice assistants, interactive voice response systems, and the dialogue capabilities of general-purpose [large language models](https://www.wikiprompt.org/wiki/large-language-model). Conversational AI sits at the intersection of [natural language processing](https://www.wikiprompt.org/wiki/natural-language-processing), [speech recognition](https://www.wikiprompt.org/wiki/speech-recognition), and, for spoken systems, [text-to-speech](https://www.wikiprompt.org/wiki/text-to-speech) synthesis.

## Components
A conversational AI system typically combines several subsystems: input understanding, which converts speech to text or parses typed text; dialogue management, which tracks conversation state, intent, and context across turns; response generation, which produces the reply, historically via templates or retrieval and increasingly via a generative language model; and, for voice interfaces, speech synthesis to convert the reply back to audio. Systems that maintain context across a multi-turn exchange rely on a model's context window to remember earlier turns, and many production systems use a [system prompt](https://www.wikiprompt.org/wiki/system-prompt) to fix persona, tone, and behavioral constraints.

## Evolution
Early conversational systems were narrow and rule-based, matching user intents to a limited menu of scripted responses, exemplified by interactive phone trees and early chatbots like [ELIZA](https://www.wikiprompt.org/wiki/eliza). The 2010s saw the rise of intent-classification-based virtual assistants, such as Siri and Alexa, that handled a fixed set of tasks such as setting timers or checking weather, typically without genuine open-domain understanding. The shift to deep learning and later [transformer](https://www.wikiprompt.org/wiki/transformer)-based language models enabled open-domain conversational ability: models could hold a coherent dialogue on almost any topic without being explicitly programmed for it, a change most visibly demonstrated by [ChatGPT](https://www.wikiprompt.org/wiki/chatgpt) and refined through [reinforcement learning from human feedback](https://www.wikiprompt.org/wiki/rlhf) to keep responses aligned with what users actually want. Later systems added [retrieval-augmented generation](https://www.wikiprompt.org/wiki/retrieval-augmented-generation) to ground answers in current or proprietary information and [tool use](https://www.wikiprompt.org/wiki/tool-use) to let the system take actions, such as searching the web or querying a database, mid-conversation.

## Applications and criticism
Conversational AI is widely deployed in customer support, healthcare triage, education, accessibility tools, and personal assistants, and is a foundation for the [AI agents](https://www.wikiprompt.org/wiki/ai-agent) that extend dialogue into autonomous task completion. Criticisms echo those of chatbots generally: hallucination of incorrect information delivered in a confident, conversational tone; the risk of users over-trusting or emotionally over-relying on systems that do not understand them; and, for voice interfaces, privacy concerns about always-listening microphones. Researchers continue to debate how much conversational fluency reflects genuine understanding versus fluent pattern completion, a question closely tied to critiques such as the [stochastic parrot](https://www.wikiprompt.org/wiki/stochastic-parrot) argument.
