基於android的語音識別

1.注冊賬戶，添加應用

 

2.針對android平台的選擇應用，下載SDK

 

3.將SDK的libs下文件拷貝到工程的libs目錄下

4.添加用戶權限

    <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.初始化語音配置對象

        //初始化語音配置對象，必須，這樣才能使用MSC語音服務
        SpeechUtility.createUtility(this, SpeechConstant.APPID+"=59454d78");

6.拷貝assets目錄下資源文件到android工程的assets目錄

 

7.識別代碼

       //創建語音識別對話框
        RecognizerDialog rd = new RecognizerDialog(this,null);
        //設置參數accent,language等參數
        rd.setParameter(SpeechConstant.LANGUAGE,"zh_cn");//中文
        rd.setParameter(SpeechConstant.ACCENT,"mandarin");//普通話
        //設置回調接口
        rd.setListener(new RecognizerDialogListener() {
            @Override
            public void onResult(RecognizerResult recognizerResult, boolean b) {
                //獲取返回結果
                String  result = recognizerResult.getResultString();
                Log.e("result",result);
                Log.e("b",b+"");
            }

            @Override
            public void onError(SpeechError speechError) {

            }
        });
        //顯示對話框
        rd.show();

8.由於返回的是json字符串所以還得解析出來才能使用

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來解析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();
    }
