Android 에 서 는 TTS(TextToSpeech)를 사용 하여 텍스트 를 음성 으로 변환 합 니 다.

TextToSpeech textToSpeech = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
            @Override
            public void onInit(int status) {
                if (status == TextToSpeech.SUCCESS) {
                    int result = textToSpeech.setLanguage(Locale.US);
                    if (result != TextToSpeech.LANG_COUNTRY_AVAILABLE && result != TextToSpeech.LANG_AVAILABLE) {
                        Toast.makeText(MainActivity.this, "       ", Toast.LENGTH_SHORT).show();
                    }
                }
            }
        });

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @TargetApi(Build.VERSION_CODES.LOLLIPOP)
            @Override
            public void onClick(View view) {
                textToSpeech.setSpeechRate(1);
                textToSpeech.speak(editText.getText().toString(), TextToSpeech.QUEUE_ADD, null, "speech");
                Snackbar.make(view, "         ", Snackbar.LENGTH_LONG)
                        .setAction("  ", new View.OnClickListener() {
                            @Override
