基于android的语音识别

1.注册账户，添加应用

2.针对android平台的选择应用，下载SDK

3.将SDK的libs下文件拷贝到工程的libs目录下

4.添加用户权限

    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.RECORD_AUDIO"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/>
    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
    <uses-permission android:name="android.permission.READ_CONTACTS"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.WRITE_SETTINGS"/>
    <uses-permission android:name="android.permission.CAMERA"/>

5.初始化语音配置对象

        //初始化语音配置对象，必须，这样才能使用MSC语音服务
        SpeechUtility.createUtility(this, SpeechConstant.APPID+"=59454d78");

6.拷贝assets目录下资源文件到android工程的assets目录

7.识别代码

       //创建语音识别对话框
        RecognizerDialog rd = new RecognizerDialog(this,null);
        //设置参数accent,language等参数
        rd.setParameter(SpeechConstant.LANGUAGE,"zh_cn");//中文
        rd.setParameter(SpeechConstant.ACCENT,"mandarin");//普通话
        //设置回调接口
        rd.setListener(new RecognizerDialogListener() {
            @Override
            public void onResult(RecognizerResult recognizerResult, boolean b) {
                //获取返回结果
                String  result = recognizerResult.getResultString();
                Log.e("result",result);
                Log.e("b",b+"");
            }

            @Override
            public void onError(SpeechError speechError) {

            }
        });
        //显示对话框
        rd.show();

8.由于返回的是json字符串所以还得解析出来才能使用

result:{"sn":2,"ls":true,"bg":0,"ed":0,"ws":[{"bg":0,"cw":[{"sc":0.00,"w":"？"}]}]}

9.解析Json字符串

        /**
         * 解析json串
         * @param result
         */
        protected String parseJsonData(String json) {
        // 使用Gson来解析Json串
            Gson gson = new Gson();
            VoiceBean bean = gson.fromJson(json, VoiceBean.class);
            ArrayList<WS> ws = bean.ws;
            StringBuffer sb = new StringBuffer();
            for (WS ws2 : ws) {
                String info = ws2.cw.get(0).w;
                sb.append(info);
            }
            return sb.toString();
    }
