android之文本转语音

发表于 更新于 分类于 Waline：

android 系统自带了文本转语音的功能

一般手机都有Pico TTS功能，但是没有中文语言包
解决方案： 安装google 语音装文本tts服务或者讯飞tts等兼容系统接口的TTs

文字转语音的代码比较少

          @Override
          public void onInit(int status) {

                      Log.e(TAG, "Language is not available.");
                      Intent installIntent = new Intent();
                      installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
                      startActivity(installIntent);
                  } else {
                      // Check the documentation for other possible result codes.
                      // For example, the language may be available for the locale,
                      // but not for the specified country and variant.
                      // The TTS engine has been successfully initialized.
                      // Allow the user to press the button for the app to speak again.
                      Log.i(TAG,"初始化成功");
                      mTts.speak("初始化成功",TextToSpeech.QUEUE_FLUSH,null);
                  }
              } else {
                  // Initialization failed.
                  Log.e(TAG, "Could not initialize TextToSpeech.");
              }
          }
      });

注意销毁 TextToSpeech

}

问题

在使用nubia手机时，发现手机没有这项（TTs）设置,安装了其它TTs却不能开启。
解决：打算用第三方sdk,但是查了一下讯飞的离线文字转语音却发现是收费的，只能说nubia的系统太坑了。
