Question

我使用SpeechRecognizer类实现语音识别的代码似乎是正确的......但它无论如何都不起作用。任何RecognitionListener方法中的日志语句都没有被记录。

我非常仔细地遵循Android参考文档，我没有看到我错过的内容。

我已添加了录音音频权限。

package com.example.voicetest;

import java.util.ArrayList;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.speech.RecognitionListener;
import android.speech.RecognizerIntent;
import android.speech.SpeechRecognizer;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class VoiceActivity extends Activity {


SpeechRecognizer recognizer;
TextView display;
private boolean listening;
private Button button1;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_voice);

    listening=false;
    display=(TextView)findViewById(R.id.textView1);
    button1=(Button)findViewById(R.id.button1);





    recognizer=SpeechRecognizer.createSpeechRecognizer(this);

    recognizer.setRecognitionListener(
                new RecognitionListener()
                {

                    @Override
                    public void onBeginningOfSpeech() {
                        // TODO Auto-generated method stub

                        display.setText("Ready and waiting..");
                        Log.i("test","onReady");
                    }

                    @Override

                        display.setText(result);

Answer 1

您还需要

intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE,
                                     this.getPackageName());

Answer 2

尝试以下方法：

注销错误代码。如果它提供服务器错误，那么您没有连接到互联网。
如果要使用离线语音识别，则需要下载语言模型。只需验证语音输入是否适用于您的键盘（按下麦克风按钮，说出一些内容并查看它是否正在转换）。如果没有得到识别，那么您的代码就没有错误，您只需要下载语音模型。

Android SpeechRecognizer服务不会调用侦听器
