我想禁用Google语音的弹出窗口。我希望它在后台运行,所以不应该出现弹出窗口。我正在使用c#在Visual Studio中编程,我想在Android上创建一个语音识别应用程序。
I downloaded the sample code from the Xamarin page
代码:
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// set the isRecording flag to false (not recording)
isRecording = false;
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
// get the resources from the layout
recButton = FindViewById<Button>(Resource.Id.btnRecord);
textBox = FindViewById<TextView>(Resource.Id.textYourText);
// check to see if we can actually record - if we can, assign the event to the button
string rec = Android.Content.PM.PackageManager.FeatureMicrophone;
if (rec != "android.hardware.microphone")
{
// no microphone, no recording. Disable the button and output an alert
var alert = new AlertDialog.Builder(recButton.Context);
alert.SetTitle("You don't seem to have a microphone to record with");
alert.SetPositiveButton("OK", (sender, e) =>
{
textBox.Text = "No microphone present";
recButton.Enabled = false;
return;
});
alert.Show();
}
else
{
recButton.Click += delegate
{
// change the text on the button
recButton.Text = "End Recording";
isRecording = !isRecording;
if (isRecording)
{
// create the intent and start the activity
var voiceIntent = new Intent(RecognizerIntent.ActionRecognizeSpeech);
voiceIntent.PutExtra(RecognizerIntent.ExtraLanguageModel, RecognizerIntent.LanguageModelFreeForm);
// put a message on the modal dialog
voiceIntent.PutExtra(RecognizerIntent.ExtraPrompt, Application.Context.GetString(Resource.String.messageSpeakNow));
// if there is more then 1.5s of silence, consider the speech over
voiceIntent.PutExtra(RecognizerIntent.ExtraSpeechInputCompleteSilenceLengthMillis, 1500);
voiceIntent.PutExtra(RecognizerIntent.ExtraSpeechInputPossiblyCompleteSilenceLengthMillis, 1500);
voiceIntent.PutExtra(RecognizerIntent.ExtraSpeechInputMinimumLengthMillis, 15000);
voiceIntent.PutExtra(RecognizerIntent.ExtraMaxResults, 1);
voiceIntent.PutExtra(RecognizerIntent.ExtraLanguage, Java.Util.Locale.German);
// you can specify other languages recognised here, for example
// if you wish it to recognise the default Locale language and German
// if you do use another locale, regional dialects may not be recognised very well
voiceIntent.PutExtra(RecognizerIntent.ExtraLanguage, Java.Util.Locale.Default);
StartActivityForResult(voiceIntent, VOICE);
}
};
}
}
protected override void OnActivityResult(int requestCode, Result resultVal, Intent data)
{
if (requestCode == VOICE)
{
if (resultVal == Result.Ok)
{
var matches = data.GetStringArrayListExtra(RecognizerIntent.ExtraResults);
if (matches.Count != 0)
{
string textInput = textBox.Text + matches[0];
// limit the output to 500 characters
if (textInput.Length > 500)
textInput = textInput.Substring(0, 500);
textBox.Text = textInput;
}
else
textBox.Text = "No speech was recognised";
// change the text back on the button
recButton.Text = "Start Recording";
}
}
base.OnActivityResult(requestCode, resultVal, data);
}
有人可以帮我禁用弹出窗口吗?
答案 0 :(得分:3)
您可以为您的应用实施SpeechRecognizer
。此API的实现可能会将音频流式传输到远程服务器以执行语音识别。
您的应用需要获得RECORD_AUDIO
权限。
例如:
public class MainActivity : Activity, IRecognitionListener
{
private TextView tv;
private SpeechRecognizer sr;
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView(Resource.Layout.Main);
sr = SpeechRecognizer.CreateSpeechRecognizer(this);
sr.SetRecognitionListener(this);
Button btn = FindViewById<Button>(Resource.Id.btn);
btn.Click += (sender, e) =>
{
Intent intent = new Intent(RecognizerIntent.ActionRecognizeSpeech);
intent.PutExtra(RecognizerIntent.ExtraLanguageModel, RecognizerIntent.LanguageModelFreeForm);
intent.PutExtra(RecognizerIntent.ExtraCallingPackage, "this package");
intent.PutExtra(RecognizerIntent.ExtraMaxResults, 5);
sr.StartListening(intent);
};
tv = FindViewById<TextView>(Resource.Id.tv);
}
public void OnBeginningOfSpeech()
{
tv.Text = "Beginning";
}
public void OnBufferReceived(byte[] buffer)
{
}
public void OnEndOfSpeech()
{
}
public void OnError([GeneratedEnum] SpeechRecognizerError error)
{
tv.Text = error.ToString();
}
public void OnEvent(int eventType, Bundle @params)
{
}
public void OnPartialResults(Bundle partialResults)
{
}
public void OnReadyForSpeech(Bundle @params)
{
tv.Text = "Ready!";
}
public void OnResults(Bundle results)
{
var data = results.GetStringArrayList(SpeechRecognizer.ResultsRecognition);
StringBuilder builder = new StringBuilder();
for (int i = 0; i < data.Count; i++)
{
builder.Append(data[i]);
}
tv.Text = builder.ToString();
}
public void OnRmsChanged(float rmsdB)
{
}
}
这仍然使用谷歌的语音服务,如果您的设备/地区不支持此服务,您需要找到其他语音服务并在您的应用中使用他们的API。
