Android Dev网站提供了使用内置Google语音输入活动进行语音输入的示例.该活动显示带麦克风的预配置弹出窗口并使用其传递结果onActivityResult()
我的问题:有没有办法SpeechRecognizer直接使用该类进行语音输入而不显示固定活动？这将让我构建自己的语音输入活动.
我的应用程序使用AsyncTask中的MediaRecorder类记录音频,并使用Google API转换语音到文本 - Recognizer Intent - 使用此问题的代码:如何在没有Android手机烦人的对话框的情况下使用语音识别
我也试过在Thread中录制音频,但这是更糟糕的解决方案.它会导致更多问题.我的问题是我的应用程序在模拟器上正常工作.但是由于缺乏语音识别服务,模拟器不支持语音重新识别.在我的设备上,当我开始录制音频和语音识别时,我的应用程序崩溃了 - "已意外停止".但是当我关闭wifi时,应用程序就像在模拟器上一样正常工作.
在AndroidManifest中录制音频需要:
<uses-permission android:name="android.permission.RECORD_AUDIO" />
和语音识别要求:
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.INTERNET" />
我想这是单音频输入的问题？我该如何解决这个问题？Google Speech Recognizer需要在主UI线程中工作,因此我无法在Async Task中执行此操作.所以我在Async Task中录音.我不知道为什么会导致问题.
我已将设备连接到Eclipse,并且我已使用USB调试.这是我在LogCat中的执行:

08-23 14:50:03.528: ERROR/ActivityThread(12403): …编辑:我应该已经提到过这个,但我在服务中运行此代码.整个应用程序由小部件按钮打开/关闭,没有任何活动.
更新:我尝试将SDK源附加到项目中,这样我就可以更准确地了解发生故障的位置,但从外观来看,只包含公共API,这似乎使它们的用处更少.任何人都可以建议至少一种调试方法来解决这个问题吗？我有点卡住了.
我正在尝试使用Android的语音识别软件包来记录用户语音并将其翻译成文本.不幸的是,当我尝试启动监听时,我收到的ANR错误并未指出任何具体内容.
正如SpeechRecognizer API指示的那样,如果您尝试从主线程调用它,则抛出RuntimeException.这会让我想知道处理是否过于苛刻......但我知道其他应用程序使用Android API就可以实现这一目的,而且它通常非常活泼.
java.lang.RuntimeException: SpeechRecognizer should be used only from the application's main thread
这是我试图从我的服务中调用的代码的一个(修剪过的)示例.这是正确的方法吗？
感谢您抽出宝贵时间提供帮助.这是一个我无法克服的障碍.

我将尝试在没有带有RecognitionListener的Google对话框的情况下使用语音识别,但在启动应用程序时只能发出蜂鸣声.我已将权限音频记录和互联网添加到清单文件中.我希望你告诉我并帮我找错...我在Log cat上没有错误...我想在用户说出问候时向一个循环显示一个消息进行循环Regognition OK并且列表视图显示结果.
public class MainActivity extends Activity implements RecognitionListener

Toast.makeText(getBaseContext(), …这就是我启动我的RecogniseListener意图的方法:

intent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true);
intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS,1);
sr.startListening(intent);
但是,我得到一个奇怪的行为.它适用于某些手机(三星galaxy S5,在这种情况下),但我在联想K50-T5上收到以下错误:
E/SpeechRecognizer: no selected voice recognition service
这是我的AndroidManifest.xml:

如果由于用户不说话而在RecognizerIntent完成的情况下如何处理图像(ImageView)的可见性
if (RecognizerIntent.EXTRA_RESULTS == null){
image1.setVisibility(View.VISIBLE);///microphone icon
}
要么
if (RecognizerIntent.ACTION_RECOGNIZE_SPEECH == null){
image1.setVisibility(View.INVISIBLE);///microphone
}
