无法在 Android 语音识别中使用长输入，初始化时出错？

Question

我正在尝试在我的应用程序（启动器）中使用 Google 语音识别。当我尝试将它用于 Call to X 之类的短命令或说出 123456789 之类的短号时，一切正常，但是一旦我尝试提供更长的输入（这需要更多时间说）语音识别活动挂在屏幕上，它没有做任何事情。

我在日志中找不到任何有用的东西，我不知道在初始化语音识别时我是否做错了。

这是我初始化它的时间：

var intent = new Intent(RecognizerIntent.ActionRecognizeSpeech);

intent.PutExtra(RecognizerIntent.ExtraLanguageModel, RecognizerIntent.LanguageModelFreeForm);
StartActivityForResult(intent, SpeechResult);

这是我使用结果的地方

protected override void OnActivityResult(int requestCode, Result resultCode, Intent data)
        {
            base.OnActivityResult(requestCode, resultCode, data);


            if (requestCode == SpeechResult && data != null)
            {

                var text = data.GetStringArrayListExtra(RecognizerIntent.ExtraResults);


                getterForNumber = text[0];
                getterForNumber = getterForNumber.Replace(" ", String.Empty);

                bool inInt = getterForNumber.All(char.IsDigit);

                if (!inInt)
                {
                    var activity2 = new Intent(this, typeof(fittizioAct));
                    activity2.PutExtra("fittizioData", "Cannot Recognise the Number");
                    activity2.PutExtra("direzione", "vocale");
                    StartActivity(activity2);
                    Finish();
                }
                else
                {
                    var passNameAndNumberRubr = new Intent(this, typeof(VocalSavedAct));
                    passNameAndNumberRubr.PutExtra("saveNumberRubr", getterForNumber);
                    passNameAndNumberRubr.PutExtra("saveNameRubr", getterForName);

                    //sqldbRubrica.AddRecord(getterForName, getterForNumber);

                    StartActivity(passNameAndNumberRubr);
                    Finish();
                }




            }
            else if (requestCode == SpeechResult && data == null)
            {
                AudioManager vol = (AudioManager)this.GetSystemService(Context.AudioService);
                int volume = vol.GetStreamVolume(Android.Media.Stream.Music);
                CrossTextToSpeech.Current.Speak("Voice Command Canceled",
                pitch: 1,
                speakRate: speed,
                volume: (float)volume,
                crossLocale: locale);
            }
}

附：代码在 C# 中，因为我使用的是 Xamarin。

尝试像这样修改初始化

var voiceIntent = new Intent(RecognizerIntent.ActionRecognizeSpeech);
            voiceIntent.PutExtra(RecognizerIntent.ExtraLanguageModel, RecognizerIntent.LanguageModelFreeForm);


            voiceIntent.PutExtra(RecognizerIntent.ExtraPrompt, "Speak now");

            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.Default);
