集成第三方平台科大讯飞语音功能的实现

第一步:

http://www.xfyun.cn/在官网注册,创建android应用,申请APP_key,下载SDK文件

具体开发指南官方的开发文档:http://www.xfyun.cn/doccenter/awd

第二步:

导入SDK中的资料到对应的文件中如图

第三步:

1.添加权限:

   <!--连接网络权限，用于执行云端语音能力 -->
    <uses-permission android:name="android.permission.INTERNET"/>
    <!--获取手机录音机使用权限，听写、识别、语义理解需要用到此权限 -->
    <uses-permission android:name="android.permission.RECORD_AUDIO"/>
    <!--读取网络信息状态 -->
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <!--获取当前wifi状态 -->
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
    <!--允许程序改变网络连接状态 -->
    <uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/>
    <!--读取手机信息权限 -->
    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
    <!--读取联系人权限，上传联系人需要用到此权限 -->
    <uses-permission android:name="android.permission.READ_CONTACTS"/>

 2.添加Gson依赖,在app/build.gradle中

compile 'com.google.code.gson:gson:2.8.0'

 3,代码功能实现:

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //初始化,记得替换自己的App_key
        SpeechUtility.createUtility(this, SpeechConstant.APPID + "=58bebbee");
        tv = (TextView) findViewById(R.id.tv);
        SynthesizerListener mSynListener = new SynthesizerListener() {
            //会话结束回调接口，没有错误时， error为null
            public void onCompleted(SpeechError error) {
            }
            //缓冲进度回调
            //percent为缓冲进度0~100， beginPos为缓冲音频在文本中开始位置， endPos表示缓冲音频在
            public void onBufferProgress(int percent, int beginPos, int endPos, String info) {
            }
            //开始播放
            public void onSpeakBegin() {
            }
            //暂停播放
            public void onSpeakPaused() {
            }
            //播放进度回调
            //percent为播放进度0~100,beginPos为播放音频在文本中开始位置， endPos表示播放音频在文
            public void onSpeakProgress(int percent, int beginPos, int endPos) {
            }
            //恢复播放回调接口
            public void onSpeakResumed() {
            }
            //会话事件回调接口
            public void onEvent(int arg0, int arg1, int arg2, Bundle arg3) {
            }
        };
        findViewById(R.id.btn_speak).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //1.创建SpeechRecognizer对象，第二个参数：本地听写时传InitListener
                RecognizerDialog iatDialog = new RecognizerDialog(MainActivity.this, new InitListener() {
                    @Override
                    public void onInit(int i) {
                    }
                });

                //2.设置听写参数
                iatDialog.setParameter(SpeechConstant.DOMAIN, "iat");
                iatDialog.setParameter(SpeechConstant.LANGUAGE, "zh_cn");//语言为普通话
                iatDialog.setParameter(SpeechConstant.ACCENT, "mandarin ");

                //3.设置回调接口
                iatDialog.setListener(new RecognizerDialogListener() {
                    @Override
                    public void onResult(RecognizerResult result, boolean isLast) {
                        String resultString = result.getResultString();
                        Gson gson = new Gson();
                        VoiceBean voiceBean = gson.fromJson(resultString, VoiceBean.class);
                        List<VoiceBean.WsBean> ws = voiceBean.ws;
                        for (int i = 0; i < ws.size(); i++) {

                                VoiceBean.WsBean.CwBean cwBean = cw.get(j);
                                String w = cwBean.w;
                                str += w;
                            }
                        }
                        if (isLast) {//判断是否说完

                    }
