Agent: Building an Intelligent Voice Experience

An Agent is the core entity in Fluents.ai that combines voice, behavior, and context—powering smooth, dynamic, and personalized AI conversations.

​
Basic Settings

Start by configuring your agent’s core identity and behavior.

  • Agent Name
    Give your agent a recognizable name.

    Select the voice gender (male or female) for the agent’s tone.

  • Agent Description
    Add a short internal description to help identify this agent’s purpose or use case.

  • Voicemail Message
    Define what the agent should say if it reaches voicemail.

  • Predefined Prompt
    Choose from saved prompts in your Prompt Library.

  • Custom Prompt
    Alternatively, add or edit a custom prompt directly.

​
Advanced Settings

Fine-tune the agent’s intelligence, responsiveness, and integrations.

  • Select a Voice
    Choose a specific voice from your created voice assets.

  • Model Language
    Define the language your agent will operate in.
