public final class TextToSpeech

  1. Object
  2. TextToSpeech

Speaks text aloud using the platform’s built-in synthesizer.

  • iOS – AVSpeechSynthesizer.
  • Android – android.speech.tts.TextToSpeech.
  • JavaSE simulator – best-effort: say on macOS, espeak on Linux, SAPI via PowerShell on Windows. When none of those tools are present, isSupported returns false and speak silently no-ops so simulator code paths keep working.

No permissions or Info.plist entries are required.

TextToSpeech.speak("Welcome to the demo");
