# What is On-device STT?

> On-device Speech-to-Text

It is a technology that converts audio into text directly on the device, without the need for internet.

## Overview
On-device voice-to-text conversion runs on the device's own processor without the need for cloud servers. In this way, privacy is protected and it is not affected by internet outages.

*Analogy: It's like being in the same room with a translator who carries the entire dictionary in his head, instead of a translator going to another room and looking up a dictionary.*

## How it works
Voice data is received by the microphone and instantly processed by the local artificial intelligence model in the device and transcribed into text.

## Where it is used
It is used in voice memo applications on smartphones and voice command systems that require privacy.

## Commonly confused with
The difference from cloud-based voice processing systems is that your data does not leave the device.

## Frequently asked questions
**Why should I choose this over the cloud?**
It does not require an internet connection and is safer because your data remains on your device.
