# Inworld Node STT

[Overview](../overview) > [Inworld Node](./InworldNode) > Inworld Node STT

**Class:** `UInworldNode_STT` | **Inherits from:** `UInworldNode`

A node that converts audio input to text using Speech-to-Text functionality.

This node takes audio input and processes it through a Speech-to-Text service to generate text output. It inherits from TypedNode with Text as output and Audio as input.

**Input Types:**

* `FInworldData_Audio` OR `FInworldData_DataStream_AudioChunk` (Audio data to convert to text)

**Output Types:**

* `FInworldData_Text`

## Execution Config

The STT node exposes an `ExecutionConfig` property (`FInworldSTTNodeExecutionConfig`) that controls whether it runs in batch or streaming mode.

| Property                  | Type      | Default     | Description                                                                                                                                                                 |
| ------------------------- | --------- | ----------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `bStreamed`               | `bool`    | `false`     | When `true`, the node uses a Streaming STT primitive and processes audio incrementally in real-time. When `false`, it sends a complete audio clip to a batch STT primitive. |
| `STTComponentId`          | `FString` | `"Default"` | The **STT Creation Config** key to use. Only visible when `bStreamed` is `false`.                                                                                           |
| `StreamingSTTComponentId` | `FString` | `"Default"` | The **Streaming STT Creation Config** key to use. Only visible when `bStreamed` is `true`.                                                                                  |

Set `bStreamed = true` when the node receives a `FInworldData_DataStream_AudioChunk` input (live microphone audio). Use the default `false` for complete pre-recorded audio clips (`FInworldData_Audio`).
