# Inworld STT Module

[Overview](../overview) > Inworld STT Module

**Class:** `InworldSTTModule` | **Inherits from:** `InworldFrameworkModule`

Module for Speech-to-Text (STT) functionality within the Inworld framework. Converts audio input into text transcriptions using AI-powered speech recognition. Supports both synchronous and asynchronous speech recognition operations.

## Methods

* [RecognizeSpeech](#recognizespeech)
* [RecognizeSpeechAsync](#recognizespeechasync)

## Reference

### RecognizeSpeech

Performs synchronous speech recognition on the provided audio chunk.
Converts audio data to text using the configured speech recognition model.

#### Parameters

| Parameter  | Type         | Description                             |
| ---------- | ------------ | --------------------------------------- |
| audioChunk | `AudioChunk` | The audio data to transcribe into text. |

#### Returns

**Type:** `string`

**Description:** The transcribed text result, or empty string if recognition failed.

***

### RecognizeSpeechAsync

Performs asynchronous speech recognition on the provided audio chunk.
Converts audio data to text using the configured speech recognition model.
Provides progress notifications through task events during processing.

#### Parameters

| Parameter  | Type         | Description                             |
| ---------- | ------------ | --------------------------------------- |
| audioChunk | `AudioChunk` | The audio data to transcribe into text. |

#### Returns

**Type:** `Awaitable<string>`

**Description:** A task that completes with the transcribed text result, or empty string if recognition failed.

## Configuration Management

### Remote Configuration

When using remote STT services, the module creates an `STTRemoteConfig` with:

* API key from framework utilities (if available)

### Local Configuration

When using local STT models, the module creates an `STTLocalConfig` with:

* Model path (resolved from StreamingAssets folder)
* Device configuration from framework utilities
