# 语音评测模块接口文档
|
||
|
||
## 概述
|
||
语音评测模块用于语文课程的语音跟读和自动评测功能，支持学生录制语音、上传音频、自动评测并记录评测结果。
|
||
|
||
## 数据库表
|
||
|
||
### voice_evaluation（语音评测表）
|
||
```sql
|
||
CREATE TABLE `voice_evaluation` (
|
||
`id` bigint NOT NULL AUTO_INCREMENT COMMENT '评测ID',
|
||
`student_id` bigint NOT NULL COMMENT '学员ID',
|
||

## 第三方语音服务集成
|
||
|
||
### 语音服务接口
|
||
|
||
系统提供了 `IVoiceEvaluationService` 接口，用于集成第三方语音评测服务。
|
||
|
||
**接口定义**:
|
||
```java
|
||
public interface IVoiceEvaluationService {
|
||
/**
|
||
* 语音评测
|
||
* @param audioPath 音频文件路径
|
||
* @param content 评测内容
|
||
* @param language 语言类型
|
||
* @return 评测结果
|
||
*/
|
||
Map<String, Object> evaluateVoice(String audioPath, String content, String language);
|
||
|
||
/**
|
||
* 检查服务是否可用
|
||
* @return true-可用，false-不可用
|
||
*/
|
||
boolean isAvailable();
|
||
}
|
||
```
|
||
|
||

|
||
5. **替换实现**：将 `VoiceEvaluationServiceImpl` 中的模拟实现替换为真实API调用
|
||
|
||
### 示例代码（科大讯飞）
|
||
|
||
```java
|
||
@Service
|
||
public class XfyunVoiceEvaluationServiceImpl implements IVoiceEvaluationService {
|
||
|
||
@Value("${voice.xfyun.appid}")
|
||
private String appId;
|
||
|
||
@Value("${voice.xfyun.apikey}")
|
||
private String apiKey;
|
||
|
||
@Value("${voice.xfyun.apisecret}")
|
||
private String apiSecret;
|
||
|
||
@Override
|
||
public Map<String, Object> evaluateVoice(String audioPath, String content, String language) {
|
||
// 1. 读取音频文件
|
||
File audioFile = new File(audioPath);
|
||
byte[] audioData = FileUtils.readFileToByteArray(audioFile);
|
||
|
||
// 2. 调用科大讯飞API
|
||
XfyunClient client = new XfyunClient(appId, apiKey, apiSecret);
|
||
EvaluationResult result = client.evaluate(audioData, content, language);
|
||
|
||
// 3. 解析返回结果
|
||
Map<String, Object> evaluationResult = new HashMap<>();
|
||
evaluationResult.put("score", result.getTotalScore());
|
||
evaluationResult.put("accuracy", result.getAccuracy());
|
||
evaluationResult.put("fluency", result.getFluency());
|
||
evaluationResult.put("completeness", result.getCompleteness());
|
||
evaluationResult.put("pronunciation", result.getPronunciation());
|
||
evaluationResult.put("resultDetail", result.getDetailJson());
|
||
|
||
return evaluationResult;
|
||
}
|
||
|
||
@Override
|
||
public boolean isAvailable() {
|
||
// 检查API密钥是否配置
|
||
return StringUtils.isNotEmpty(appId) &&
|
||
StringUtils.isNotEmpty(apiKey) &&
|
||
StringUtils.isNotEmpty(apiSecret);
|
||
}
|
||
}
|
||
```
|
||
|

|
||
|
||
## 前端页面
|
||
|
||
### UniApp端
|
||
|
||
**页面路径**: `frontend-uniapp/src/pages/voice/evaluation.vue`
|
||
|
||
**功能**:
|
||
- 设置评测内容
|
||
- 语音录制（开始/停止）
|
||
- 播放录音
|
||
- 上传音频并评测
|
||
- 查看评测结果
|
||
- 查看历史记录
|
||
|
||
**使用方式**:
|
||
```javascript
|
||
// 跳转到语音评测页面
|
||
uni.navigateTo({
|
||
url: '/pages/voice/evaluation?courseId=1&courseName=语文课程&content=评测内容'
|
||
})
|
||
```
|
||
|
||
### 管理后台
|
||
|
||
**页面路径**: `ruoyi-ui/src/views/study/voiceEvaluation/index.vue`
|
||
|
||
**功能**:
|
||
- 查询语音评测列表
|
||
- 查看评测详情
|
||
- 删除评测记录
|
||
- 导出评测数据
|
||
|
||
---
|
||
|
||
## 使用说明
|
||
|
||
### 1. 数据库初始化
|
||
|
||
执行SQL脚本创建表：
|
||
```bash
|
||
mysql -u root -p ry_study < log/Sql/voice_evaluation_table.sql
|
||
```
|
||
|
||
### 2. 配置第三方服务（可选）
|
||
|
||
如果需要使用真实的语音评测服务，需要：
|
||
|
||
1. 在 `application.yml` 中配置API密钥：
|
||
```yaml
|
||
voice:
|
||
xfyun:
|
||
appid: your_app_id
|
||
apikey: your_api_key
|
||
apisecret: your_api_secret
|
||
```
|
||
|
||
2. 实现 `IVoiceEvaluationService` 接口
|
||
3. 替换 `VoiceEvaluationServiceImpl` 中的实现
|
||
|
||
### 3. 测试
|
||
|
||
1. **UniApp端测试**：
|
||
- 打开语音评测页面
|
||
- 输入评测内容
|
||
- 录制语音
|
||
- 上传并评测
|
||
- 查看评测结果
|
||
|
||
2. **管理后台测试**：
|
||
- 登录管理后台
|
||
- 进入"学习系统" -> "语音评测"
|
||
- 查看评测列表
|
||
- 查看评测详情
|
||
|
||

|
||
|
||
## 注意事项
|
||
|
||
1. **音频格式**：支持mp3、wav等常见音频格式
|
||
2. **文件大小**：建议音频文件不超过10MB
|
||
3. **录音时长**：建议录音时长不超过60秒
|
||
4. **第三方服务**：当前使用模拟实现，实际使用时需要接入真实的第三方服务
|
||
5. **权限控制**：教师只能查看自己班级学员的评测记录（通过数据权限控制）
