    1.1 What is Text-to-Speech?

    Text-to-Speech (TTS) is a technology that converts written text into spoken words. TTS has various applications, including accessibility features, voice assistants, and entertainment services.

    1.2 Why use ElevenLabs API?

    ElevenLabs provides a robust and developer-friendly TTS API. Using their API simplifies the integration process, allowing you to focus on building the application’s features rather than dealing with the complexities of speech synthesis.

    Before starting, ensure that you have the following:

    • Basic knowledge of PHP and Laravel
    • Composer installed
    • An account on ElevenLabs to obtain an API key
    • Text editor or integrated development environment (IDE)
  • 2: Set Up Laravel Project

    2.1 Installing Laravel

    If you don’t have a Laravel project yet, use the Laravel installer to make a new project or start working in one that already exists.
