# Voice agent quick start guide
> Build and launch your first voice agent in 3 minutes or less.
Create, configure, and call your first voice agent on Voiceflow. No coding required.
**1. Create a new project**
From the [Dashboard](https://creator.voiceflow.com), go to **Projects** → **New project**. Name your project, set the type to **Voice**, and select **Start from scratch**.
This opens the global agent view, where you'll configure your agent's high-level behavior.
**2. Set up your agent's persona**
In the **Global agent** description, click **generate** and describe your agent's actions, goals, and personality. You can also customize the agent's tone, speed, and how long it waits for a user to reply. Voiceflow will automatically create a detailed prompt in seconds.
For example:
```text theme={null}
You are Alex, a calm and friendly voice support agent for AcmeCorp.
Help customers with orders, returns, billing, and product questions.
Speak naturally in short, conversational sentences — avoid long
lists or complex phrasing. Stay warm, patient, and reassuring.
If you can't resolve an issue, offer to create a support ticket.
```
**3. Add a knowledge base (optional)**
To give your agent real information to reference, click the **Knowledge Base** icon in the left sidebar. You can add context by:
* **Uploading documents** - PDFs, text files, or CSVs (e.g., your FAQ, product catalog, or return policy).
* **Pasting a URL** - Your agent will index the content directly from the page.
* **Adding text manually** - Paste in key information directly.
Your agent will use this knowledge to answer questions accurately.
**4. Publish and call your agent**
Back in the **Agent** tab, click **Publish** in the top-right corner. To receive a call from your agent, click **Call** in the top-right, enter your phone number, and start speaking with your agent!
That's it! Your agent is now deployed and available to use.
## Tips for refining your voice agent
* **Start simple.** Get a basic agent working first, then layer on complexity. You can add deterministic [Workflows](https://www.voiceflow.com/docs/documentation/build/workflows.md) and agentic [Playbooks](https://www.voiceflow.com/docs/documentation/build/playbooks.md) to get the most out of your agent.
* **Use your knowledge base.** The more relevant content you upload, the more accurate your agent's responses will be.
* **Iterate on your prompt.** Small tweaks to the system prompt can make a big difference in response quality.
* **Set up a phone number.** [Configure a dedicated number](https://www.voiceflow.com/docs/documentation/deploy/phone/connect-a-phone-number.md) so your agent can be reached by simply dialing in.
