Java实现文字转语音播报

一、pom.xml引入jar包依赖

<!-- https://mvnrepository.com/artifact/com.jacob/jacob 文字转语音 -->
<dependency>
 <groupId>com.hynnet</groupId>
 <artifactId>jacob</artifactId>
 <version>1.18</version>
</dependency>

二、把jacob-1.18-x64.dll文件复制到jdk安装位置的bin目录下。

三、工具类

package com.jykj.demo.utils;

import com.jacob.activeX.ActiveXComponent;
import com.jacob.com.Dispatch;
import com.jacob.com.Variant;

public class TextToSpeechUtil {
    
    

    public static void main(String[] args) {
    
    
        textToSpeech("你好呀！小爱同学");
    }

        /**

         *
         * @param txt
         */
        public static void textToSpeech(String text) {
    
    
            ActiveXComponent ax = null;
            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(text));

                // 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("./text.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(text));

                // 关闭输出文件
                Dispatch.call(spFileStream, "Close");
                Dispatch.putRef(spVoice, "AudioOutputStream", null);

                spAudioFormat.safeRelease();
                spFileStream.safeRelease();
                spVoice.safeRelease();
                ax.safeRelease();

            } catch (Exception e) {
    
    
                e.printStackTrace();
            }
