Android TextToSpeech 总是无法运行

Question

出于某种原因，尽管我已验证所需的数据文件可用，但总是调用 onInit() 并显示错误代码。

我试过启动 TTS（文本到语音）代码，该代码是从教程中完整复制的，但也不起作用

以下是我的初始化代码：

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == DATA_CHECK_SUCCESS) {

            if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
                textToSpeech = new TextToSpeech(this, this);
            }

            else {

                Intent installTTSIntent = new Intent();
                installTTSIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
                startActivity(installTTSIntent);

            }

        }

    }

    @Override
    public void onInit(int initStatus) {

        if (initStatus == TextToSpeech.SUCCESS) {
            if(textToSpeech.isLanguageAvailable(Locale.US)==TextToSpeech.LANG_AVAILABLE)
                textToSpeech.setLanguage(Locale.US);
        }
        else if (initStatus == TextToSpeech.ERROR) {
            Toast.makeText(this, "Sorry! Text To Speech failed...", Toast.LENGTH_LONG).show();
        }

    }

   

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        Intent TTSIntent = new Intent();
        TTSIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
        startActivityForResult(TTSIntent, DATA_CHECK_SUCCESS);

    }

提前致谢

Answer 1

我之前在使用 Speech to Text 时遇到过类似的问题，问题是设备上安装的 Google 应用程序被禁用或没有麦克风权限。

检查这是否有助于解决您的问题。

事实证明这是 Android 模拟器随 Android studio 提供的问题，因为它不提供 TTS
