讯飞SDK图文使用说明 语音听写 语音合成 声纹密码 人脸识别（适配Android7.0）

关于讯飞，他们关于语音做的AI功能SDK特别好，我经过使用有了深刻的体验，这次讲一讲语音听写、语音合成、声纹密码、人脸识别这三种的功能的体验。

1.首先到讯飞开放平台注册账号，然后到右上角点击我的应用创建应用，并给应用添加新功能

/

2.然后在我的应用界面点击对应应用的栏目的SDK下载按钮跳转页面，这里我可以看到语音听写、人脸识别、语音合成、声纹识别都是免费的，然后其他的几个有体验标识的功能，每天也也可以使用500。

3.我们点击SDK下载按钮就会下载一个压缩包，解压后我们把sample文件夹下speechDemo文件夹的代码都移植到Android Studio上，因为这些代码原本都是Android Studio上创建的，所以不用改什么。我这里是直接创建一个包名一样的project，然后把speechDemo文件夹的代码直接移植过去。移植完后，还需要将根目录的assets、libs、res文件直接复制过去，选择全部覆盖。

4.适配Android6.0权限申请

在MainActivity的onCreate函数里加入以下代码

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {requestPermissions(new String[]{Manifest.permission.READ_PHONE_STATE, Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.RECORD_AUDIO, Manifest.permission.READ_CONTACTS,Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.READ_EXTERNAL_STORAGE,Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.CAMERA}, 1001);}

5.适配Android7.0

首先在AndroidManifest里添加一个相机权限，因为有的手机调用系统相机需要这个权限

<uses-permission android:name="android.permission.CAMERA"/>

然后修改OnlineFaceDemo这个类，

public class OnlineFaceDemo extends Activity implements View.OnClickListener {private final String TAG = "OnlineFaceDemo";private final int REQUEST_PICTURE_CHOOSE = 1;private final int REQUEST_CAMERA_IMAGE = 2;private Bitmap mImage = null;private byte[] mImageData = null;// authid为6-18个字符长度，用于唯一标识用户private String mAuthid = null;private Toast mToast;// 进度对话框private ProgressDialog

其中需要我们新建一个类，为了专门完成调用系统相机和相册，也是为了替代项目中FaceUtil类，因为他不适配Android7.0

运行项目安装app，

首先是语音听写，点击开始我们就可以说话了，他也会弹出一个对话框显示正在录音，你也可以再点击一下屏幕，它会停止录音。这个听写的准确度，一般还可以，但是对于声音相似的单词就容易错。然后使用这个听写是不需要流量的。

然后是在线语音合成，其实就是把文字语音播放出来，与语音听写相对立。这个功能需要流量，然后我们可以选择发音人。

最后一个是声纹密码，首先输入authId，这个其实就是相当于用户名，你就随便输入几个字母，然后点击获取密码，然后点击声纹注册再点击开始录音，他会让你读一段数字，这个录音要进行五次。然后点击1：1验证，再点击开始录音，这个时候他会让你读一段数字，然后他判断你是否是这个authId所代表的用户。

最后是人脸识别，首先是填写authid，然后是选图（调用系统相册）或者拍照（调用系统相机），注册。注册成功后，你就可以通过再次选图或者拍照，点击1：1验证，可以通过两次图片判断是否是同一个人。他还有人脸模型删除，和1：N验证
