如何整合文本到语音功能?

以下是我的代码: -

public class TtsActivity extends Activity implements OnInitListener {

    private int MY_DATA_CHECK_CODE = 0;

    private TextToSpeech tts;

    private EditText inputText;
    private Button speakButton;

    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        inputText = (EditText) findViewById(R.id.input_text);
        speakButton = (Button) findViewById(R.id.speak_button);

        speakButton.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                String text = inputText.getText().toString();
                if (text != null && text.length() > 0) {
                    Toast.makeText(TtsActivity.this, "Saying: " + text,
                            Toast.LENGTH_LONG).show();
                    tts.speak(text, TextToSpeech.QUEUE_ADD, null);
                }
            }
        });

        Intent checkIntent = new Intent();
        checkIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
        startActivityForResult(checkIntent, MY_DATA_CHECK_CODE);

    }

    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == MY_DATA_CHECK_CODE) {
            System.out.println("Code is:- " + requestCode);
            System.out.println("Code is:- " + resultCode);
            if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
                System.out.println("Code is:- " + resultCode);
                // success, create the TTS instance
                tts = new TextToSpeech(this, this);
            } else {
                System.out.println("Code is:- " + resultCode);
                // missing data, install it
                Intent installIntent = new Intent();
                installIntent
                        .setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
                startActivity(installIntent);
            }
        }

    }

    @Override
    public void onInit(int status) {
        if (status == TextToSpeech.SUCCESS) {
            Toast.makeText(TtsActivity.this,
                    "Text-To-Speech engine is initialized", Toast.LENGTH_LONG)
                    .show();
        } else if (status == TextToSpeech.ERROR) {
            Toast.makeText(TtsActivity.this,
                    "Error occurred while initializing Text-To-Speech engine",
                    Toast.LENGTH_LONG).show();
        }
    }
}

如果我运行上面的代码,谷歌Android市场是开放的,如果我安装应用程序然后文本到语音是完成工作,但如果我没有安装应用程序错误发生。

所以,请帮助我。

这是因为Text To Speech在您的设备上需要TTS引擎。如果您的设备上没有安装TTS引擎,它会将您重定向到市场并允许您下载相同的内容。所以在您安装该引擎后,您的应用会找到TTS引擎并在您的设备上正常工作。

TextToSpeech mTts;
mTts = new TextToSpeech(this,
            this  // TextToSpeech.OnInitListener
            );
...
mTts.setPitch(2.3); //change it as per your need
...
mTts.speak(s,TextToSpeech.QUEUE_FLUSH,null);
