Agents

An agent is the brain of your experience.
It listens, understands, and responds—just like a human conversation partner.
Agents may also be referred to as “AI Agents”, “Intelligent Agents”, “Voice Agents”, or “Voice Bots”.
In practice, an agent is made up of different AI components:
  • STT (Speech-to-Text) – converts your voice into text.
  • LLM (Large Language Model) – understands the text, reasons, and generates a reply.
  • TTS (Text-to-Speech) – transforms the reply into natural-sounding audio.
  • VAD (Voice Activity Detection) – detects when you’re speaking so the agent knows when to listen.
Alternatively, you can use S2S (speech-to-speech) real-time models like Google Gemini or OpenAI Realtime, which combine these steps into a single, ultra-fast pipeline.

​
Behavior & Persona

An agent’s behavior is shaped by the prompts (or instructions) you give it. This includes defining its tone (friendly, professional, playful), its identity (name, role, background), and its scope (what it can and cannot talk about).
You can make an agent act like a customer support representative, a language tutor, a virtual coach, or any persona you want.
We invite you to read our stories on how companies leverage agents to create unique experiences.

​
Avatars

An avatar is the face of your agent.
It gives a visual identity to your agent, making interactions more engaging and human-like. Avatars can be hyper-realistic humans, semi-realistic (video game characters), or animated cartoons that lip-syncs to the agent’s voice.
Equos avatars need only a single picture to perfectly match identity. It can come from a photo, a painting, an illustration, or even an AI-generated image.

​
Sessions

A session is a conversation with an avatar (and its agent).
Every time a user starts talking to an avatar, a session begins.
This allows you to track, manage, and analyze conversations in a structured way. Why sessions matter:
  • Keep conversations organized (per user, per time).
  • Store chat history for continuity.
  • Measure performance (length, satisfaction, conversion).
  • Build personalized experiences (remember user preferences across sessions).
What’s a session?
Imagine a “session” like opening a support chat window or starting a Zoom call.
It begins when you connect and ends when the conversation finishes.

​
How it all fits together

  • An agent powers the conversation (the brain).
  • An avatar gives it a presence (the face).
  • A session brings them together during each interaction (the container).
With Equos, you can connect all these pieces in just a few steps—whether you want a simple voice bot, or a fully animated avatar that speaks dozens of languages.
