A conversational agent, or better , a conversational system, is a computer system intended to converse with a human in a natural langue.

Let's see what wikipedia states for conversational agent:

A dialogue system, or conversational agent (CA), is a computer system intended to converse with a human. Dialogue systems employed one or more of text, speech, graphics, haptics, gestures, and other modes for communication on both the input and output channel.[1].

In common practice, conversational agent in an umbrella term generally used as synonym of chatbot, even if a chatbot is a conversational agent that communicate just via texts, on chat-based platforms (as instant-messaging mobile apps).

Especially in academic parlance, the term conversational agent was synonym of chatbot, and the reason emphasis on the "agent" was maybe because conversational agents was considered a special application in intelligent systems[2] or Multi-agent systems[3] research.

The term "agent" is probably misleading, because assimilating any conversational system as an agent that mediate between an end-user (e.g. a consumer of a business platform) and a business human operator. That's in general not true. Instead the agentive role is commonly related to a special case of conversational system that act as intermediator, requiring a final conversation with a human operator (that's commonly called, in customer service realms: human-in-the-loop).

But there are many cases where the conversational system is not properly an agent, by example in pure command-and-control conversational systems that just execute automation commands to action (electro-mechanical) actuators, by example in home-automation or industrial automation realms.

Nevertheless the concept of "conversational agent", even if ambiguous, is currently an active area of research of virtual assistants, in the sense of a real agentive/automation technology that assists humans to solve real-life problems, in real-time in a reactive and proactive way (co called mixed-initiative). Voice assistants are a special case of virtual assistants[4], where the human-computer interaction is mainly done via voice (voicefirst). Smartspeakers are HW device terminals that enable humans to interact with a (voice) assistant.
