我有一个需求，我想在我的音乐播放器想加入一个百度语音识别功能。在搜索页加了一个按钮，跳转到百度识别界面，返回识别结果，调用搜索歌曲功能。
自建SpeechRecognitionActivity.java
public class SpeechRecognitionActivity extends AppCompatActivity implements EventListener {
protected SearchEditText etSearch;
protected Button startBtn; //
protected Button stopBtn; //
private EventManager asr;//语音识别核心库
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_recording);
ImageView asr_gif = (ImageView) findViewById(R.id.img_gif);
Glide.with(this).load(R.drawable.asr).into(asr_gif);
initPermission();
initView();
// 初始化EventEventManager对象
asr = EventManagerFactory.create(this, "asr");
// 注册自己的输出事件类
asr.registerListener(this);
}
/**
* android 6.0 以上需要动态申请权限
*/
private void initPermission() {
String permissions[] = {Manifest.permission.RECORD_AUDIO,
Manifest.permission.ACCESS_NETWORK_STATE,
Manifest.permission.INTERNET,
Manifest.permission.WRITE_EXTERNAL_STORAGE
};
ArrayList<String> toApplyList = new ArrayList<String>();
for (String perm : permissions) {
if (PackageManager.PERMISSION_GRANTED != ContextCompat.checkSelfPermission(this, perm)) {
toApplyList.add(perm);
}
}
String tmpList[] = new String[toApplyList.size()];
if (!toApplyList.isEmpty()) {
ActivityCompat.requestPermissions(this, toApplyList.toArray(tmpList), 123);
}
}
/**
* 权限申请回调，可以作进一步处理
* @param requestCode
* @param permissions
* @param grantResults
*/
@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
// 此处为android 6.0以上动态授权的回调，用户自行实现。
super.onRequestPermissionsResult(requestCode, permissions, grantResults);
}
/**
* 初始化控件
*/
private void initView() {
etSearch = (SearchEditText) findViewById(R.id.et_search);
startBtn = (Button) findViewById(R.id.btn_start);
stopBtn = (Button) findViewById(R.id.btn_stop);
startBtn.setOnClickListener(new View.OnClickListener() {//开始
@Override
public void onClick(View v) {
asr.send(SpeechConstant.ASR_START, "{}", null, 0, 0);
}
});
stopBtn.setOnClickListener(new View.OnClickListener() {//停止
@Override
public void onClick(View v) {
asr.send(SpeechConstant.ASR_STOP, "{}", null, 0, 0);
}
});
}
/**
* 自定义输出事件类 EventListener 回调方法
*/
@Override
public void onEvent(String name, String params, byte[] data, int offset, int length) {
if (name.equals(SpeechConstant.CALLBACK_EVENT_ASR_PARTIAL)) {
// 识别相关的结果都在这里
if (params == null || params.isEmpty()) {
return;
}
if (params.contains("\"final_result\"")) {
// 一句话的最终识别结果
Log.i("asr.event", params);
Gson gson = new Gson();
AsrResponseBean asRresponse = gson.fromJson(params, AsrResponseBean.class);//数据解析转实体bean
if(asRresponse == null) return;
//从日志中，得出Best_result的值才是需要的，但是后面跟了一个中文输入法下的逗号，
if(asRresponse.getBest_result().contains("，")){//包含逗号 则将逗号替换为空格
etSearch.setText(asRresponse.getBest_result().replace('，',' ').trim());//替换为空格之后，通过trim去掉字符串的首尾空格
}else {//不包含
etSearch.setText(asRresponse.getBest_result().trim());
}
}
}
}
@Override
protected void onDestroy() {
super.onDestroy();
//发送取消事件
asr.send(SpeechConstant.ASR_CANCEL, "{}", null, 0, 0);
//退出事件管理器
// 必须与registerListener成对出现，否则可能造成内存泄露
asr.unregisterListener(this);
}
