Java语音转文字及文字转语音教学 （离线版）

1. 语音转文字

        1.1 maven导入以下包

<!-- 获取音频信息 --><dependency> <groupId>org</groupId> <artifactId>jaudiotagger</artifactId> <version>2.0.3</version></dependency><!-- 语音识别 --><dependency> <groupId>net.java.dev.jna</groupId> <artifactId>jna</artifactId> <version>5.7.0</version></dependency><dependency> <groupId>com.alphacephei</groupId> <artifactId>vosk</artifactId> <version>0.3.32</version></dependency>

        1.2 编写代码

import java.io.FileInputStream;import java.io.BufferedInputStream;import java.io.IOException;import java.io.InputStream;import javax.sound.sampled.AudioSystem;import javax.sound.sampled.UnsupportedAudioFileException;import org.vosk.LogLevel;import org.vosk.Recognizer;import org.vosk.LibVosk;import org.vosk.Model;public class DecoderDemo {    public static void main(String[] argv) throws IOException, UnsupportedAudioFileException {        LibVosk.setLogLevel(LogLevel.DEBUG);        try (Model model = new Model("D:\\model\\vosk-model-small-cn-0.22");                    InputStream ais = AudioSystem.getAudioInputStream(new BufferedInputStream(new FileInputStream("D:\\File\\badao.wav")));                    Recognizer recognizer = new Recognizer(model, 16000)) {            int bytes;            byte[] b = new byte[4096];            while ((bytes = ais.read(b)) >= 0) {                recognizer.acceptWaveForm(b, bytes);            }            System.out.println(recognizer.getFinalResult() + System.lineSeparator());        }    }}

注意new Model("模型路径")是你下载的模型解压后的地址

InputStream ais = AudioSystem.getAudioInputStream(new BufferedInputStream(new FileInputStream("音频路径"))); 这个是你要识别的音频地址，我用的音频格式是 wav 其他格式还没试。

没有模型可以去网址： https://alphacephei.com/vosk/models 下载

选择 Chinese 下载这两个模型 （建议都下载 small模型识别快一点）

下载后记得解压在使用

2. 文字转语音

        2.1 Maven导入以下包

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

        2.2 编写代码

import com.jacob.activeX.ActiveXComponent;import com.jacob.com.Dispatch;import com.jacob.com.Variant;public class TxtToSoundUtils {    public static void main(String[] args) {        textToSpeech("打开卧室灯泡");        System.out.println("生成成功！");    }    /**     * 语音转文字并播放     *     * @param text     */    public static void textToSpeech(String text) {        ActiveXComponent ax;        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("D:\\File\\TestFile.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();        }    }}

到此就完成了 语音转文字 文字转语音的功能了，希望能帮到你。有疑问评论
