java - 如果我运行一次语音到文本，那么文本到语音不起作用，只显示吐司

Question

代码很好，但是当我点击语音到文本时，文本到语音不起作用

这是java文件

public class icanhearandspeak extends Activity {
TextToSpeech t2;
EditText ed2;
Button b2;
protected static final int RESULT_SPEECH = 1;
private ImageButton btnSpeak1;
private TextView txtText1;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.xyxyxyxyxyx);
    ed2 = (EditText) findViewById(R.id.editText1);
    b2 = (Button) findViewById(R.id.button5);
    txtText1 = (TextView) findViewById(R.id.txtText1);
    btnSpeak1 = (ImageButton) findViewById(R.id.btnSpeak1);
    t2 = new TextToSpeech(getApplicationContext(), new TextToSpeech.OnInitListener() {
        @Override
        public void onInit(int status) {
            if (status != TextToSpeech.SUCCESS) {
                t2.setLanguage(Locale.UK);
            }
        }
    });
    b2.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            String toSpeak = ed2.getText().toString();
            Toast.makeText(getApplicationContext(), toSpeak, Toast.LENGTH_SHORT).show();
            t2.speak(toSpeak, TextToSpeech.QUEUE_FLUSH, null);
        }
    });
    btnSpeak1.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(
                    RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
            intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en-US");
            try {
                startActivityForResult(intent, RESULT_SPEECH);
                txtText1.setText("");
            } catch (ActivityNotFoundException a) {
                Toast t = Toast.makeText(getApplicationContext(),
                        "Opps! Your device doesn't support Speech to Text",
                        Toast.LENGTH_SHORT);
                t.show();
            }
        }
    });
}
public void onPause() {
    if (t2 != null) {
        t2.stop();
        t2.shutdown();
    }
    super.onPause();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.menu_main, menu);
    return true;
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    switch (requestCode) {
        case RESULT_SPEECH: {
            if (resultCode == RESULT_OK && null != data) {
                ArrayList<String> text = data
                        .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);

                txtText1.setText(text.get(0));
            }
            break;
        }

    }
}

}

这是我的 xml 文件，它有一个按钮，可以收听音频并将其转换为文本和编辑文本，无论用户写什么都将转换为语音

代码运行流畅，但是一旦我将语音转换为文本并尝试将文本转换为语音，它将无法正常工作，它只会显示吐司，但文本不会转换为语音
