Turn Text into MP3 Using macOS Voices + PHP + FFmpeg No AI API Needed

Описание: In this video I show how to build a **local Text-to-Speech engine using macOS voices**, PHP, and FFmpeg.

Instead of using paid AI APIs, macOS already includes a powerful speech synthesis engine through the `say` command.

By downloading additional voices from **Accessibility → Live Speech → Manage Voices**, you can generate high-quality speech in multiple languages.

In this tutorial we will:

• Install additional macOS voice packs
• Use the `say` terminal command to generate speech
• Build a PHP script to automate text-to-speech
• Generate `.m4a` audio files
• Convert them to `.mp3` using FFmpeg

This approach is useful for:

• Podcast automation
• Radio automation systems
• AI narration tools
• Voice announcements
• Audio generation pipelines

Tools used in this tutorial:

macOS Speech Engine
PHP
FFmpeg

Example command used:

```
say -v "Jaya (Enhanced)" "Hello world" -o speech.m4a
```

Then convert to MP3:

```
ffmpeg -i speech.m4a -codec:a libmp3lame speech.mp3
```

This allows you to build your own *text-to-speech production pipeline locally* without relying on external services.
