工作：我想要一个类似的应用程序“当我调用该方法时，它将启动语音识别器并提供语音识别结果
问题：语音识别器在我调用方法时启动，但它没有立即给出语音识别的结果。它给出了第二次呼叫时第一次呼叫的结果。
我的代码： 语音识别类：
package com.ooo.voicerecog;
import java.util.ArrayList;
import android.Manifest;
import android.content.pm.PackageManager;
import android.os.Build;

speech.startListening(recognizerIntent);

speech.stopListening();
return text;

你可以这样做。它不会打开谷歌提示并开始收听。下面的行就是诀窍
speechIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
代码：
speechIntent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
speechIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
speechIntent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, context.getPackageName());
// for more: https://stackoverflow.com/questions/7973023/what-is-the-list-of-supported-languages-locales-on-android
/*intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "en_IN"); */
speechIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.getDefault());
speechIntent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 1);
speechIntent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_MINIMUM_LENGTH_MILLIS, 10000);
speechIntent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_COMPLETE_SILENCE_LENGTH_MILLIS, new Long(5000));
speechIntent.putExtra(RecognizerIntent.EXTRA_SPEECH_INPUT_POSSIBLY_COMPLETE_SILENCE_LENGTH_MILLIS, new Long(5000));
speechIntent.putExtra("android.speech.extra.DICTATION_MODE", false);
speechIntent.putExtra(RecognizerIntent.EXTRA_PARTIAL_RESULTS, true);
/*
intent.putExtra("android.speech.extra.GET_AUDIO_FORMAT", "audio/AMR");
intent.putExtra("android.speech.extra.GET_AUDIO", true);
*/
isRecognizerRunning = true;
sr.startListening(speechIntent);
并使用自定义类
监听它class listener implements RecognitionListener {
public void onReadyForSpeech(Bundle params) {
CommonUtilities._Log(CommonUtilities.logs.e, TAG, "onReadyForSpeech");
}
public void onBeginningOfSpeech() {
CommonUtilities._Log(CommonUtilities.logs.e, TAG, "onBeginningOfSpeech");
}
public void onRmsChanged(float rmsdB) {
}
public void onBufferReceived(byte[] buffer) {
CommonUtilities._Log(CommonUtilities.logs.e, TAG, "onBufferReceived");
}
public void onEndOfSpeech() {
CommonUtilities._Log(CommonUtilities.logs.e, TAG, "onEndofSpeech");
isRecognizerRunning = false;
}
public void onError(int error) {
String message;
switch (error) {
case SpeechRecognizer.ERROR_AUDIO:
message = "Audio recording error";
break;
case SpeechRecognizer.ERROR_CLIENT:
message = "Client side error";
break;
case SpeechRecognizer.ERROR_INSUFFICIENT_PERMISSIONS:
message = "Insufficient permissions";
break;
case SpeechRecognizer.ERROR_NETWORK:
message = "Network error";
break;
case SpeechRecognizer.ERROR_NETWORK_TIMEOUT:
message = "Network timeout";
break;
case SpeechRecognizer.ERROR_NO_MATCH:
message = "No match";
break;
case SpeechRecognizer.ERROR_RECOGNIZER_BUSY:
message = "RecognitionService busy";
break;
case SpeechRecognizer.ERROR_SERVER:
message = "error from server";
break;
case SpeechRecognizer.ERROR_SPEECH_TIMEOUT:
message = "No speech input";
break;
default:
message = "Didn't understand, please try again.";
break;
}
}
public void onResults(Bundle results) {
String str = "";
ArrayList data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
for (int i = 0; i < data.size(); i++) {
CommonUtilities._Log(CommonUtilities.logs.e, TAG, "onResults result " + data.get(i) + " size " + data.size());
str += data.get(i);
}
if (!data.get(0).toString().trim().isEmpty()) {
checkAndPerformAction(data.get(0).toString()); // best match
}
}
public void onPartialResults(Bundle partialResults) {
String str = "";
ArrayList data = partialResults.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
CommonUtilities._Log(CommonUtilities.logs.e, TAG, "onPartialResults " + data.get(0).toString());
String[] partial = data.get(0).toString().split(" ");
if (partial.length > previousPartialResults.length) {
