基于百度AI的人脸识别及语音合成课题
课题需求
（1）人脸识别
在Web界面上传人的照片，后台使用Java技术接收图片，然后对图片进行解码，调用云平台接口识别人脸特征，接收平台返回的人员年龄、性别、颜值等信息，将信息返回到Web界面进行显示。
（2）人脸比对
在Web界面上传两张人的照片，后台使用Java技术接收图片，然后对图片进行解码，调用云平台接口比对照片信息，返回相似度。
（3）语音识别
在Web页面上传语音文件，判断语音文件格式，如果不是wav格式进行转码处理，然后调用平台接口进行识别，最后将识别的文本内容返回到Web界面进行显示。
（4）语音合成
在Web界面上传文本内容和语音类型，后台接收文本内容和语音类型后，调用平台接口生成语音数据，最后将数据转码成mp3格式文件，Web界面可以下载到本地。
课题设计
课题基于客户端—服务端-平台端构架，客户端主要实现功能界面展示、数据上传和处理结果展示；服务器端接收客户端数据、数据转码处理、平台接口调用、请求结果相应；平台端介绍服务端数据、人脸识别、人脸比对、语音识别、语音合成等。

接口规范
数据交互类型：JSON
请求数据：请求数据除了请求参数以外，还需另外发送以下参数：(否则会返回403状态码)
返回数据格式：
{"status": "200","msg":"","data": {"namename":"user","password":"password"}}
（1）人脸识别
接口名：FaceDetect
请求参数：
返回参数：
（2）人脸比对
接口名：FaceMatch
请求参数：
返回参数：
（3）语音识别
接口名：VoiceRecognize
请求参数：
返回参数：
（4）语音生成
接口名：VoiceGen
返回参数：
Mp3音频格式文件
请求注意事项
请求体格式化：Content-Type为application/json，通过json格式化请求体。
Base64编码：请求的图片需经过Base64编码，图片的base64编码指将图片数据编码成一串字符串，使用该字符串代替图像地址。您可以首先得到图片的二进制，然后用Base64格式编码即可。需要注意的是，图片的base64编码是不包含图片头的，如data:image/jpg;base64,
图片格式：现支持PNG、JPG、JPEG、BMP，不支持GIF图片
实例代码
1. 人脸识别实例代码
// 配置请求参数
HashMap<String, String> options = new HashMap<String, String>();
options.put("face_field", "age,gender,glasses,beauty,expression");
options.put("max_face_num", "2");
options.put("face_type", "LIVE");
// 转换成base64
String image = Base64Util.part2Base64(imagePart);
String imageType = "BASE64";
// 接口调用，并返回JSON数据
JSONObject json = client.detect(image, imageType, options);
// 响应数据处理
Map<String, Object> map = new HashMap<>();
// 获取人脸信息列表
JSONObject result = json.getJSONObject("result").getJSONArray("face_list").getJSONObject(0);
// 响应数据：性别
JSONObject genderObj = result.getJSONObject("gender");
String genderStr = genderObj.getString("type");
if(genderObj.getDouble("probability") >= 0.6) {//概率并转换
if("female".equals(genderStr)) {
genderStr = "女";
}else if("male".equals(genderStr)) {
genderStr = "男";
}
}
map.put("gender", genderStr);
// 返回接口数据
return ResponseData.success(map);
2. 人脸对比实例代码
// 转换成base64
String image1 = Base64Util.part2Base64(imagePart1);
String image2 = Base64Util.part2Base64(imagePart2);
// 封装平台接口请求对象
MatchRequest req1 = new MatchRequest(image1, "BASE64");
MatchRequest req2 = new MatchRequest(image2, "BASE64");
ArrayList<MatchRequest> requests = new ArrayList<MatchRequest>();
requests.add(req1);
requests.add(req2);
// 人脸匹配
JSONObject json = client.match(requests);
// 响应数据处理
Map<String, Object> map = new HashMap<>();
// 匹配分值
double score = json.getJSONObject("result").getDouble("score");
return ResponseData.success(map);
3. 语音识别实例代码
// 文件类型
String fileType = voicePart.getContentType();
if(fileType.endsWith("mp3")) {
fileType = MP3;
}else if(fileType.endsWith("wav")) {
fileType = WAV;
}else {
return ResponseData.fail("请上传mp3、wav音频");
}
try {
// 获取音频字符流
InputStream is = voicePart.getInputStream();
// 保存临时音频文件
String filename = new SimpleDateFormat("yyyyMMddHHmmssSSS").format(Calendar.getInstance().getTime());
File tmpVoice = new File(workspace + File.separator + filename+fileType);
VoiceUtil.saveVoiceFile(is, tmpVoice);
if(fileType.equals(MP3)) {
File mp3File = tmpVoice;
tmpVoice = new File(tmpVoice.getPath().replace(MP3, WAV));
if(!VoiceUtil.mp3ToWav(mp3File, tmpVoice)) {
return ResponseData.fail("mp3音频文件错误，请用wav音频。");
}
mp3File.delete();
}
// 调用百度接口
JSONObject json = client.asr(tmpVoice.getPath(), "wav", 16000, null);
tmpVoice.delete();
Integer status = json.getInt("err_no"); //状态码
if(status != 0) {
// 异常响应处理
String msg = json.getString("err_msg");
log.warn("百度接口调用响应异常,error_code:"+status + " error_msg:"+msg);
return ResponseData.fail(msg);
}
// 响应数据处理
Map<String, Object> map = new HashMap<>();
// 获取结果
JSONArray jsonArray = json.getJSONArray("result");
// 识别文本
String text = jsonArray.getString(0);
map.put("text", text);
return ResponseData.success(map);
} catch (Exception e) {
log.warn("识别音频文件错误：", e);;
}
4. 语音合成实例代码
// 请求参数
HashMap<String, Object> options = new HashMap<String, Object>();
// 语速，取值0-9，默认为5中语速
options.put("spd", "5");
// 音调，取值0-9，默认为5中语调
options.put("pit", "5");
// 发音人选择, 0为女声，1为男声， 3为情感合成-度逍遥，4为情感合成-度丫丫，默认为普通女
options.put("per", voiceType);
// 调用百度api接口
TtsResponse res = client.synthesis(text, "zh", 1, options);
byte[] data = res.getData();
return data;

PS：欢迎大家给予评论、建议和下载学习，下面为源码的一些说明
- AIProject.zip 为后端代码，为eclipse项目，app.properties文件需要自己配置百度云开发平台的AppID、APIKey、SecretKey。
- Web.zip 为前端代码，前后端分离，可直接运行使用 。
- 运行环境，对版本没太大要求，但jdk和tomcat要对应 JDK：我使用的版本为JDK1.8，官方下载地址
Tomcat：，我使用的版本为tomcat 9，官方下载地址；- 注意需要百度云开放平台的AppID、APIKey、SecretKey，百度云AI开放平台：http://ai.baidu.com/
