1.实现效果如下：

输入文字（支持中英文），点击转换生成***.wav文件，点击下载到本地就可。

生成后的音频文件播放,时长1分8秒

2.实现代码：

这次采用jacob实现，相比百度AI需要联网，本项目定位内网环境实现。所以最终采jacob。

1.环境配置：

本次采用版本jacob-1.19，我们需要下载jacob.jar和dll

下载地址：jacob语音生成文件，jacobx64.dll和jacob.jar为1.9-Java文档类资源-CSDN下载

官网地址：JACOB - Java COM Bridge download |

下载后得到两个文件：

jacob.dll：配置到jdk环境中

jacob.jar：放入到项目中并配置下pox和Idea 的dependencies下

第一步：

jacob.dll放入：C:\Program Files\Java\jdk1.8.0_121\jre\bin

第二步：

1.首先有一个spring boot项目，没有就搭建一个

2.把jacob放到项目resources>lib目录下

3.在pom.xml文件添加依赖：

<!--添加本地的jacob.jar包--><dependency><groupId>com.jacob</groupId><artifactId>jacob</artifactId><version>1.19</version><!--system使用本地jar包--><scope>system</scope><systemPath>${basedir}/src/main/resources/lib/jacob.jar</systemPath></dependency>

4.在idea下的项目中添加依赖包，

5.这样环境就搭建完成。

2.编码：

核心代码，这样就可以输入文字，生成音频文件保存到本地目录中，然后下载音频文件就只需要读取文件就可以。

//输入文本内容，生成文件地址 text为输入的文本信息public void audioFile(String text){try {//jacob.dll没成功安装，执行这一步会出错//构建音频格式 调用注册表应用Dispatch spAudioFormat = new ActiveXComponent("Sapi.SpAudioFormat").getObject();//音频文件输出流Dispatch spFileStream = new ActiveXComponent("Sapi.SpFileStream").getObject();//构建音频对象Dispatch spVoice = new ActiveXComponent("Sapi.SpVoice").getObject();//设置spAudioFormat音频流格式类型22Dispatch.put(spAudioFormat, "Type", new Variant(22));//设置spFileStream文件输出流的音频格式Dispatch.putRef(spFileStream, "Format", spAudioFormat);//设置spFileStream文件输出流参数地址等 Dispatch.call(spFileStream, "Open", new Variant("D:\speech\48641486.wav"), new Variant(3), new Variant(true));//设置spVoice声音对象的音频输出流为输出文件对象Dispatch.putRef(spVoice, "AudioOutputStream", spFileStream);//设置spVoice声音对象的音量大小100Dispatch.put(spVoice, "Volume", new Variant(100));//设置spVoice声音对象的速度 0为正常速度，范围【..-2 -1 0 1 2..】Dispatch.put(spVoice, "Rate", new Variant(0));//设置spVoice声音对象中的文本内容Dispatch.call(spVoice, "Speak", new Variant(text));//关闭spFileStream输出文件Dispatch.call(spFileStream, "Close");//释放资源spVoice.safeRelease();spAudioFormat.safeRelease();spFileStream.safeRelease();}catch (Exception e){System.out.println(e.getMessage());}}

3.其他业务代码：非核心

下面就贴上完整的项目代码和配置文件

1.项目结构：

主要就几个文件：HomeController、TextToSpeechFileService、index.html、pom.xml

2.pom.xml文件

通过上面的几个文件代码，就可以实现文章前面web页面的效果了。

本文章只是一个demo演示。应用到具体业务中还需要做一些修改。
