  • Contains an array of language options with codes, names, and native names.
  • languages: An array of objects representing different languages.

The web page uses HTML for structure, CSS for styling, and JavaScript for functionality. It incorporates the Web Speech API to convert spoken language to text. Users can choose a language, start/stop speech recognition, and perform actions like copying, downloading, and clearing the resulting text. The language options are stored in a separate JavaScript file for modularity.

In summary, the code integrates web technologies to create a user-friendly Speech To Text converter with a clean and visually appealing interface.
