Android Text-to-Speech: Complete Guide

In Android, the TextToSpeech class can be used to convert text to speech. This class allows for converting text into speech and playing it out loud.

Here is a basic usage example of the TextToSpeech class:

1. Instantiate a TextToSpeech object:

TextToSpeech tts = new TextToSpeech(context, new TextToSpeech.OnInitListener() {
    @Override
    public void onInit(int status) {
        if (status != TextToSpeech.ERROR) {
            // TextToSpeech初始化成功
        }
    }
});

1. Convert the text into speech and play it.

String text = "Hello, how are you?";
tts.speak(text, TextToSpeech.QUEUE_FLUSH, null, null);

In the example above, create a TextToSpeech object and initialize it first, then convert the text to speech and play it using the speak method.

It is important to note that when using the TextToSpeech class, you need to make sure that the device has the appropriate speech engine and speech data. You can ensure the TextToSpeech class works properly by checking if the corresponding speech engine is installed.
