# Generate Speech

> Convert text to speech using a speech synthesis model.

Generate Speech turns text into spoken audio using a speech synthesis model.

This node runs on a selectable model and consumes credits when it runs.

## When to use

* Voiceovers
* Narration
* Audio ads

## Inputs

<ParamField body="Text" type="text" required>
  The text to speak. Required. Supports loop mode.
</ParamField>

<Note>
  **Inline prompt.** You don't need a separate Text Prompt node for fixed text —
  type it directly on the node. The inline field appears whenever the text input is
  unconnected and disappears once you wire a text input in. Connect a Text Prompt node
  only when you want to drive the text from upstream or expose it as an app input.
  Type `@` to mention a connected input by name — text inputs insert their content into
  the text, media inputs insert their name.
</Note>

## Outputs

<ParamField body="Audio" type="audio">
  The generated speech.
</ParamField>

## Configuration

<ParamField body="voice" type="string" default="">
  The voice to use for synthesis.

<ParamField body="language" type="string" default="en">
  Language code for the spoken output.

<ParamField body="stability" type="number" default={0.5}>
  Voice stability, from 0 to 1. Higher values produce a more consistent delivery.

<ParamField body="similarity_boost" type="number" default={0.75}>
  How closely the output matches the chosen voice, from 0 to 1.
</ParamField>

<ParamField body="style" type="number" default={0}>
  Style exaggeration, from 0 to 1.
