Text To Speech (TTS)

Setup a speaker

var tts by remember { mutableStateOf<TextToSpeech?>(null) }
var ttsReady by remember { mutableStateOf(false) }

LaunchedEffect(Unit) {
    tts = TextToSpeech(context) { status ->
        if (status == TextToSpeech.SUCCESS) {
            tts?.language = Locale.US
            ttsReady = true
        }
    }
}

DisposableEffect(Unit) {
    onDispose {
        tts?.stop()
        tts?.shutdown()
    }
}

Speak the text

tts?.speak(text, TextToSpeech.QUEUE_FLUSH, null, null)

Queue Options

The second parameter decides the TTS engine behavior when there’s new text to speak:
