# Playground

The **Playground** is your live testing environment for Voice AI Agents. It lets you simulate real user interactions — **by chat, browser call, or phone call** — so you can validate and refine your setup before going live.

### Three Ways to Test Your Voice AI Agent

#### 1. Simulate Chat (Text Mode)

* **How it works**: Use the message box to type user queries and see how the agent responds in real time.
* **Advantages**:
  * Quick way to test logic and conversational flow.
  * Works even if voice settings or telephony aren’t configured yet.
* **Best for**:
  * Early testing of prompt, knowledge base, and decision logic.
  * Validating fallback or error handling.

***

#### 2. Test via Web Call (Browser Mode)

* **How it works**: Click **Test via web call** to initiate a voice interaction right in your browser using your mic and speakers.
* **Advantages**:
  * Zero setup — no phone number needed.
  * Fastest way to test the full voice pipeline: STT → LLM → TTS.
* **Best for**:
  * Tuning voice tone, pronunciation, pacing, and latency.
  * Debugging voice interruptions (barge-in), silence detection, etc.

***

#### 3. Get Call from Agent (Phone Mode)

* **How it works**: Input your phone number and receive a real incoming call from your Voice Agent.
* **Advantages**:
  * Full end-to-end telephony test, including call routing and quality over cellular networks.
  * Best simulates how customers will interact in production.
* **Usage Note**:
  * You’ll see a notice like:\
    *“4 credits per minute will be charged if using Chatzy’s number.”*
  * This makes it easy to estimate call testing cost.

### Conversation Panel

* **Transcript View**: Shows real-time logs of both user and agent messages (voice or text).
* **Reset Chat**: Clears the session so you can restart instantly.
* **Manual Input**: Type messages directly or speak via mic depending on the test mode.
