實現步驟：

1. 建立TextToSpeech物件，建立時傳入OnInitListener監聽器
2. 設定TextToSpeech所使用的語言、國家選項
3. 呼叫speak()或synthesizeToFile方法
4. 關閉TTS，回收資源

• 在佈局中加入EditText用於獲取文字，加入Button用於控制播放或儲存合成的聲音檔案
• 程式碼：
  
  • 初始化

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
 
, "暫不支援該語言", Toast.LENGTH_SHORT).show();
                    }
                }
            }
        });

• 播放或儲存為檔案

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, "是否儲存該聲音檔案", Snackbar.LENGTH_LONG)
                        .setAction("儲存", new View.OnClickListener() {
                            @Override
                            public void onClick(View v) {
                                textToSpeech.synthesizeToFile(editText.getText().toString(), null, new File("/mnt/sdcard/sound.mp3"), "record");
                                Toast.makeText(MainActivity.this, "儲存成功", Toast.LENGTH_SHORT).show();
                            }
                        }).show();
            }
        });

• 回收資源

protected void onDestroy() {
        super.onDestroy();
        if (textToSpeech != null) {
            textToSpeech.shutdown();
        }
    }
