Short answer

How can I change my voice assistant's settings?

You use your agent to send commands that trigger Vapi tools. Your agent can list existing personas, create new ones, or tweak the prompts and voices of current assistants. You get full control over the persona's behavior and sound.

The outcomes

What you can control

Your agent handles the technical adjustments to your voice personas.

PERSONA

New voice personas

Your agent builds entirely new assistants from scratch. You define the initial personality and voice settings immediately.

UPDATES

Refine existing voices

Change how an assistant behaves by updating its system prompt or model. This lets you fix awkward phrasing or change the tone on the fly.

INVENTORY

View all assistants

Your agent pulls a full list of your configured personas. This helps you keep track of every voice you've deployed.

HUMAN

Manual voice selection

The AI manages the configuration, but you decide which specific voice models to use. You maintain final say over the auditory identity.

The workflow

What your AI does when you request a change.

The agent translates your natural language requests into specific API calls to Vapi.

  1. Audit current setup

    The agent checks your Vapi account to see which assistants are already active.

    list_assistants

  2. Build a persona

    When you want a new voice, the agent sets up the initial configuration and parameters.

    create_assistant

  3. Modify behavior

    The agent rewrites system prompts or switches models to change how an assistant responds.

    update_assistant

  4. Verify changes

    The agent confirms the new settings are applied so you know the persona is ready.

    Can I change the actual audio files used for voices?

    No. The agent can update settings and model parameters, but it cannot upload or manage custom audio files.

  • 03

    How do I see which assistants I have?

    Just ask your agent to list your assistants, and it will pull the current inventory from Vapi.

  • 04

    Yes. You can tell your agent to create a new assistant with specific instructions and settings.

  • 05

    Will the AI change my settings without asking?
