基於android的語音辨識

標籤：com   iter   選擇   image   tor   set   基於   bsp   源檔案   

1.註冊賬戶，添加應用

 

2.針對android平台的選擇應用，下載SDK

 

3.將SDK的libs下檔案拷貝到工程的libs目錄下

4.添加使用者權限

    <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.初始化語音設定物件

        //初始化語音設定物件，必須，這樣才能使用MSCVoice Messaging Service        SpeechUtility.createUtility(this, SpeechConstant.APPID+"=59454d78");

6.拷貝assets目錄下資源檔到android工程的assets目錄

 

7.識別代碼

       //建立語音辨識對話方塊        RecognizerDialog rd = new RecognizerDialog(this,null);        //設定參數accent,language等參數        rd.setParameter(SpeechConstant.LANGUAGE,"zh_cn");//中文        rd.setParameter(SpeechConstant.ACCENT,"mandarin");//普通話        //設定回調介面        rd.setListener(new RecognizerDialogListener() {            @Override            public void onResult(RecognizerResult recognizerResult, boolean b) {                //擷取返回結果                String  result = recognizerResult.getResultString();                Log.e("result",result);                Log.e("b",b+"");            }            @Override            public void onError(SpeechError speechError) {            }        });        //顯示對話方塊        rd.show();

8.由於返回的是json字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();    }
