API Overview

  • Provides text-to-speech capabilities using the system’s speech synthesis engine. Converts text into speech using the specified language and optional gender preferences.

    This class leverages the AVSpeechSynthesizer to convert text messages into spoken voice. It allows customization of the voice’s language and gender. It supports various message formats, including plain text and Speech Synthesis Markup Language (SSML).

    You could use the following code to check if the specific voice for the given language is present on your device or not.

    import AVFoundation

let languageCode = "en-US" // you can change this to the desired language code
if SystemTextToSpeechEngine.isVoiceAvailable(for: languageCode) {
    // Creates an instance of ``SystemTextToSpeechEngine``
} else {
    // Guide the user to download the voice or use a fallback
}
