# macOS Text-to-Speech

## Overview

The macOS Text-to-Speech (TTS) service uses the macOS "say" command for producing spoken text.

Obviously, this service only works on a host that is running macOS.

## Configuration

There is no need to configure anything for this service.

## Voices

It automatically scans all available voices and registers them, see e.g.

```
