# Text to Speech

Trusys provides a built-in **Text-to-Audio** utility that allows you to convert text prompts from a spreadsheet into high-quality, natural-sounding audio files at scale.\
This tool is especially useful for generating synthetic audio datasets, voice AI testing, localization, and conversational simulations.

***

## Overview

The **Text-to-Audio** tool enables you to:

* Upload a file containing text prompts
* Customize voice delivery using emotions, accents, and filler words
* Convert each row into an individual audio file
* Download all generated audio files as a single ZIP archive

Each row in the uploaded file is processed independently and converted into a separate audio output.

***

## Upload csv File

Each row in the upoaded csv file should contain a single text prompt that will be converted into audio.

> Ensure the text is clean and well-formatted for best audio quality.

***

## Audio Customization Options

### Text-to-Audio

Convert your text into natural-sounding speech with fine-grained control over delivery and tone.

***

### Add Filler Words?

Choose whether the generated audio should include natural conversational fillers (e.g., “um”, “uh”, “you know”).

* **Yes** – Adds filler words for a more conversational and human-like tone
* **No** – Produces clean, direct speech without fillers

***

### Select Emotion(s) \*

Add emotional delivery to your audio using emotion tags.\
These emotions influence tone, pitch, and pacing.

**Examples:**

* `[happy]`
* `[sad]`
* `[angry]`
* `[whispering]`
* `[excited]`

You may select one or multiple emotions depending on the desired output style.

***

### Select Accent

Choose the accent for the voice to match your target audience or use case.

**Examples:** American, Welsh, Bengali and many more
Accent selection impacts pronunciation, intonation, and speech rhythm.

Once all options are configured:

1. Click **Convert to Audio**
2. Trusys processes each row in the uploaded file
3. An audio file is generated for every text prompt

***

## Download Output

After conversion:

* All generated audio files are bundled into a single **ZIP file**
* Each file is named based on its corresponding row or identifier
* Download the ZIP file to access and use the audio outputs locally
