一、业务场景

最近笔者在业务中涉及到语音告警的模块，需要讲告警内容以文件或流形式返回给前端进行语音播报，具体的分析与处理如下

二、业务分析

首先告警内容提示信息这里做的处理是通过专门字段去存储、编辑，根据拟定好的代码逻辑判断是否触发语音告警操作，比较重要的是考虑用那种api实现文字转语音功能，这里笔者选用的是阿里云的nls语音服务。

三、解决方案

1、pom文件引入

<dependency><groupId>com.alibaba.nls</groupId><artifactId>nls-sdk-tts</artifactId><version>2.2.1</version>
</dependency>

2、yml文件配置添加

#  nls语音配置
ali:nls:##产品相关信息app-key: access-key-id: access-key-secret: ##语音信息（声音类型、语速）voice: sijiapitch-rate: -68speech-rate: 0

3、实体类构建

import lombok.Data;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.stereotype.Component;@Data
@Component
@ConfigurationProperties(prefix = "ali.nls")
public class NlsProperties {private String appKey;private String accessKeyId;private String accessKeySecret;private String url;//发音人private String voice;//语调，范围是-500~500，可选，默认是0private Integer pitchRate;//语速，范围是-500~500，默认是0private Integer speechRate;}

4、config类构建

import com.demo.NlsProperties;
import com.demo.NlsTemplate;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.core.StringRedisTemplate;@Configuration
public class NlsAutoConfiguration {@Beanpublic NlsTemplate nlsTemplate(NlsProperties nlsProperties, StringRedisTemplate stringRedisTemplate){return new NlsTemplate(nlsProperties,stringRedisTemplate);}}

5、服务类构建

import cn.hutool.json.JSONObject;
import cn.hutool.json.JSONUtil;
import com.alibaba.nls.client.AccessToken;
import com.alibaba.nls.client.protocol.OutputFormatEnum;
import com.alibaba.nls.client.protocol.SampleRateEnum;
import com.demo.NlsProperties;
import lombok.RequiredArgsConstructor;
import lombok.SneakyThrows;
import lombok.extern.slf4j.Slf4j;
import okhttp3.*;
import org.springframework.data.redis.core.StringRedisTemplate;
import java.io.*;
import java.util.Date;@Slf4j
@RequiredArgsConstructor
