# Audio nodes

> Generate and enhance speech in Creative Studio — text-to-speech with ElevenLabs or Gemini voices, dialogue generation, voice cloning, and audio enhancement.

Audio nodes produce speech and audio assets for ads, Hyperframes voiceovers, URL-to-video handoffs, and standalone Studio video pipelines. Add an audio node to any canvas, choose a mode, and connect the output to downstream video or export nodes.

## What audio modes are available?

<Tabs>
  <Tab title="TTS (text-to-speech)">
    Convert a script to natural-sounding speech. Paste or type your text, choose a voice, and generate.

    **Default engine:** ElevenLabs V3. Gemini TTS is also available as an alternative.

    **Best for:** voiceovers, ad narration, product explainers, Hyperframes scripts.
  </Tab>

  <Tab title="Dialogue">
    Generate multi-turn or conversational speech — two or more distinct speakers in sequence, useful for interview-style or call-and-response content.

    **Best for:** podcast-style ads, scripted conversations, multi-character scenes.
  </Tab>

  <Tab title="Voice selector">
    Browse and preview available voices before committing to a full generation run. Sample any voice with a short test phrase.

    **Best for:** finding the right voice tone and accent for your brand or campaign.
  </Tab>

  <Tab title="Voice clone">
    Upload a reference audio sample to create a custom voice that sounds like a specific person or persona. Credits apply for clone creation.

    **Best for:** consistent brand voice, spokesperson content, localized campaigns with a familiar voice.
  </Tab>

  <Tab title="Enhance">
    Clean up existing audio — reduce noise, normalize levels, and improve clarity. Feed any uploaded audio file or upstream audio node output.

    **Best for:** improving recorded VO, cleaning location audio, prepping assets for lip sync.
  </Tab>
</Tabs>

## How do you use audio in a video pipeline?

<Steps>
  <Step title="Add an audio node">
    Open the toolbar and add an Audio node. Choose TTS or Dialogue mode.
  </Step>

  <Step title="Write your script">
    Type or paste the script into the text field. For Dialogue mode, label each speaker turn.
  </Step>

  <Step title="Select a voice">
    Use the Voice selector mode to preview options, then switch back to TTS and apply your chosen voice.
  </Step>

  <Step title="Generate">
    Click **Run**. The audio renders as a waveform output on the node.
  </Step>

  <Step title="Connect to video or export">
    Drag the audio output to a lip sync node, a Hyperframes voiceover slot, or an export/merge node.
  </Step>
</Steps>

<Tip>
  For Hyperframes, generate voiceover at the **Voiceover** stage rather than attaching a separate audio node — Hyperframes handles timing alignment automatically when you use the built-in voiceover step.
</Tip>
