1. 语音转文字

        1.1 maven导入以下包

<code><!-- 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

<code><!-- 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
