无法将字符串从 Speech to Text 传递到 Google 的 Text To Speech 服务。需要帮助

Question

我正在制作一个应用程序，它可以获取我讲话的上下文并通过语音回复相同的内容。就像我说 "Hello my name is John"，它应该回复我说 "Hello my name is John"。我在 Android Studio 中使用 Google 的 STT 和 TTS 服务编写了一个程序。我遇到的问题是，只有 STT 运行良好，但 TTS 似乎无法获取从 STT 接收到的字符串。

请看一下代码。

private TextToSpeech tts;

@Override

    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    txtSpeechInput = (TextView) findViewById(R.id.txtSpeechInput);
    btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);

    // hide the action bar
    getActionBar().hide();

    btnSpeak.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            promptSpeechInput();
        }
    });

    tts = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
        @Override
        public void onInit(int status) {
            if (status == TextToSpeech.SUCCESS) {
                int result = tts.setLanguage(Locale.US);
                if (result == TextToSpeech.LANG_MISSING_DATA || result == TextToSpeech.LANG_NOT_SUPPORTED) {
                    Log.e("TTS", "This Language is not supported");
                }
