# Text-to-Speech

### 🔊 Text-to-Speech (TTS)

Docufi3d supports AI-powered text-to-speech synthesis for accessibility, compliance, and user convenience. This feature allows users to **listen** to document content directly in the browser as a streamed MP3.

***

#### 🎯 Use Cases

* Improve accessibility for visually impaired users
* Enable document review while multitasking or on the go
* Assist users in understanding complex legal language by hearing it aloud

***

#### 🔧 How It Works

1. **Text Extraction**
   * Extracted from uploaded document (via OCR or PDF parser)
   * Header/footer content removed before synthesis (optional)
2. **Synthesis Engine**
   * Uses AI-based TTS engine 
3. **Audio File Generation**
   * Output is saved or streamed as `.mp3`
   * Cached for repeat playback

***

#### 🔐 Privacy & Consent

* TTS files are generated securely

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docufi3d.gitbook.io/docufi3d/ai-tools/text-to-speech.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
