## 场景 ##

在服务端根据执行的中文文字内容合成相应的音频文件。

这里推荐一种在Windows下调用jacob.dll文件实现语音合成。

## 实现 ##

首先需要下载jacob的dll文件和jar包。

下载之后将其解压

然后这里面就会有需要的dll文件和jar包。

首先找到JAVA环境变量配置的JAVA\_HOME下的bin目录,这里是

C:\\Program Files\\Java\\jdk1.8.0\_241\\bin

然后将上面的两个dll复制到此路径下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 1][]

然后打开Eclipse，新建一个Java Project

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 2][]

然后新建lib文件夹，将上面的jar包复制到lib下，然后在src下新建包，包下新建main方法

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 3][]

然后在项目上右键-Build Path -Config Build Path

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 4][]

然后在Libraries中Add JARs 将lib下的jar包添加进来，点击Apply and Close

然后修改main方法如下

package com.badao.jacob;
    
    import com.jacob.activeX.ActiveXComponent;
    import com.jacob.com.Dispatch;
    import com.jacob.com.Variant;
    
    public class TTSMain {
    
     public static void main(String[] args) {
      ActiveXComponent ax = null;
          String str="公众号:霸道的程序猿";
          try { ax = new ActiveXComponent("Sapi.SpVoice");
    
              //运行时输出语音内容
              Dispatch spVoice = ax.getObject();
              // 音量 0-100
              ax.setProperty("Volume", new Variant(100));
              // 语音朗读速度 -10 到 +10
              ax.setProperty("Rate", new Variant(-2));
              // 执行朗读
              Dispatch.call(spVoice, "Speak", new Variant(str));
    
              //下面是构建文件流把生成语音文件
    
              ax = new ActiveXComponent("Sapi.SpFileStream");
              Dispatch spFileStream = ax.getObject();
    
              ax = new ActiveXComponent("Sapi.SpAudioFormat");
              Dispatch spAudioFormat = ax.getObject();
    
              //设置音频流格式
              Dispatch.put(spAudioFormat, "Type", new Variant(22));
              //设置文件输出流格式
              Dispatch.putRef(spFileStream, "Format", spAudioFormat);
              //调用输出 文件流打开方法，创建一个.wav文件
              Dispatch.call(spFileStream, "Open", new Variant("D:\\badao.wav"), new Variant(3), new Variant(true));
              //设置声音对象的音频输出流为输出文件对象
              Dispatch.putRef(spVoice, "AudioOutputStream", spFileStream);
              //设置音量 0到100
              Dispatch.put(spVoice, "Volume", new Variant(100));
              //设置朗读速度
              Dispatch.put(spVoice, "Rate", new Variant(-2));
              //开始朗读
              Dispatch.call(spVoice, "Speak", new Variant(str));
    
              //关闭输出文件
              Dispatch.call(spFileStream, "Close");
              Dispatch.putRef(spVoice, "AudioOutputStream", null);
    
              spAudioFormat.safeRelease();
              spFileStream.safeRelease();
              spVoice.safeRelease();
              ax.safeRelease();
              System.out.println("语音合成成功");
    
          } catch (Exception e) { e.printStackTrace();
          }
     }
    
    }

这里指定生成的音频文件的路径为

D:\\\\badao.wav

确保此路径存在，然后在此右键Run AS-Java Application

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0JBREFPX0xJVU1BTkdfUUlaSEk_size_16_color_FFFFFF_t_70 5][]

没有报错并输出成功信息则会在指定路径下生成音频文件。
