# TTS Playground

> Explore TTS models and test voices

The TTS Playground makes it easy to try out Inworld's TTS capabilities through an interactive playground. It can be used to find the perfect voice for your project, test different text inputs, adjust voice settings, and experiment with audio markup tags.

## Get Started

<Steps titleSize="h3">
  <Step title="Go to Inworld Portal" iconType="light">
    In [Portal](https://platform.inworld.ai/), select **TTS Playground** from the left-hand side panel.
  </Step>

  <Step title="Enter text">
    Enter the text you want to convert to speech. If you need some ideas, you can select one of the suggestion chips at the bottom of the screen. Note that character limits in TTS playground depend on your plan, see the [Pricing page](https://inworld.ai/pricing) for details. You can also use our API to generate longer content, see [Long Text Input](/tts/capabilities/long-text-input).
  </Step>

  <Step title="Select a voice">
    On the right-hand side, click on the voice dropdown to browse available voices. You can filter by language or search by name, and click the play button next to each voice to hear how the voice sounds. Select a voice.
  </Step>

  <Step title="Generate speech">
    Click the "Generate" button on the bottom right. The audio will automatically start playing once it's been generated. You can also download the clip to save it.
  </Step>
</Steps>

## Advanced Features

For greater control over the generated audio, you can try out the following:

1. **Try a different model** - Select a different model from the right-hand side panel to see how it compares. See [Models](/tts/tts-models) for more information about each model.
2. **Adjust configurations** - Use the sliders on the right-hand side panel to adjust Temperature and Talking Speed. See [here](/tts/capabilities/generating-audio#additional-configurations) for more information.
3. **Add pauses** - Try adding SSML break tags like `<break time="1s" />` to insert pauses in your speech. See [Pause Controls](/tts/capabilities/pause-controls) for more information.

## Create a Voice

In the TTS Playground, click **+ Create a Voice** to design a new voice from a text description or clone one from audio:

* **[Voice Design](/tts/voice-design)** — Describe the voice you want in text (age, accent, tone, etc.) and get AI-generated voice candidates
* **[Voice Cloning](/tts/voice-cloning)** — Clone a voice from as little as 3 seconds of audio (up to 15 seconds — longer samples improve similarity)

## Audio Generation History

Open the History panel using the button next to **Generate** at the bottom of the playground. Every clip you generate is automatically saved there, capturing the voice, model, and text used. From the History panel you can:

* **Replay any past generation instantly** — cached audio plays without re-running the model
* **Reload settings into the playground** — send a past entry back to populate the text, voice, model, and all generation parameters in one click
* **Search and filter** by text content, voice, model, or date
* **Bulk manage entries** — enter Manage mode to multi-select for download or deletion
* **Download individual takes** as MP3 with one click

History is stored locally per device and per workspace — it isn't synced across browsers or shared between teammates. Clearing browser storage will reset it.
