功能要求:使用java 调用科大讯飞 实现会议录音,语音转写会议既要功能。 科大讯飞官网有api,还有具体的实例,可以实现关于语音需求的大部分功能。先注册,注册后会生成appid和SECRET_KEY 。
根据我的个人需求:我调用的是这个api方法即可。

**
这里涉及一个科大讯飞的sdk包,需要下载,并配置maven。**

具体代码如下,根据提供的实例改写:涉及到了5个方法类第一、LfasrSDKDemo,主函数入口,功能包括一个录音界面方法,以及语音转写方法调用。

    }

    /**

    private static List<OgMeet> getMeets(Integer pageSize,Integer pageNum) throws IOException {
          List<OgMeet> ogMeets=new ArrayList<>();
          JSONObject jsonObject= (JSONObject) JSONObject.parse(getDangjianLogin());
          System.out.println("jsonObject=================="+jsonObject);
          if(jsonObject.get("code").equals(200)){

                 OgMeet ogMeet=new OgMeet();
                 ogMeet.setMeetId(js.get("meetId").toString());
                 ogMeet.setMeetName((String)js.get("meetName"));
                 ogMeet.setStartTime((String)js.get("startTime"));
                 ogMeet.setEndsTime((String)js.get("endsTime"));
                 ogMeets.add(ogMeet);
             }
          }
          return  ogMeets;
    }


    //调用党建接口 上传
    public static String upload(String filepath) throws IOException {
        HttpClient client = HttpClients.createDefault();
        HttpPost request = new HttpPost(fileUploadPath);
        // 设置文件类型:

        File file = new File(filepath);
        MultipartEntityBuilder multipartEntityBuilder = MultipartEntityBuilder.create();

        // 示例-2:使用扩展业务参数

        // 示例-3:使用网络代理
        //netProxy();

        // 示例-4:使用性能调优参数
        //performance();
    }

}

第二、OgMeet,自定义的会议对象实体类,没什么好说的

package com.jsbs.fxffjcpt.utils.LuyinHy.sdkTurn;


import com.fasterxml.jackson.annotation.JsonFormat;
import com.ruoyi.common.annotation.Excel;
import com.ruoyi.common.core.domain.BaseEntity;
import org.apache.commons.lang3.builder.ToStringBuilder;
import org.apache.commons.lang3.builder.ToStringStyle;

import java.util.Date;

/**
 * 组织生活-会议对象 og_meet
 * 
 * @author Donfei
 * @date 2021-04-23
 */
public class OgMeet extends BaseEntity
{
    private static final long serialVersionUID = 1L;

    /** 会议id */
    private String meetId;

    /** 会议名称 */
    private String meetName;

    /** 会议开始时间 */
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private String startTime;

    /** 会议结束时间 */
    @JsonFormat(pattern = "yyyy-MM-dd HH:mm:ss")
    private String endsTime;

    public String getMeetId() {
        return meetId;
    }

    public void setMeetId(String meetId) {
        this.meetId = meetId;
    }

    public String getMeetName() {
        return meetName;
    }

    public void setMeetName(String meetName) {
        this.meetName = meetName;
    }

    public String getStartTime() {
        return startTime;
    }

    public void setStartTime(String startTime) {
        this.startTime = startTime;
    }

    public String getEndsTime() {
        return endsTime;
    }

    public void setEndsTime(String endsTime) {
        this.endsTime = endsTime;
    }
}

第三、自定义的ResDemo 科大讯飞实体类,没什么好说的。

package com.jsbs.fxffjcpt.utils.LuyinHy.sdkTurn;


/***
 * 构造科大讯飞接口返回的实体类
 *
 * */
public class ResDemo {
 private String bg;
 private String ed;
 private String onebest;
 private String speaker;

    public String getBg() {
        return bg;
    }

    public void setBg(String bg) {
        this.bg = bg;
    }

    public String getEd() {
        return ed;
    }

    public void setEd(String ed) {
        this.ed = ed;
    }

    public String getOnebest() {
        return onebest;
    }

    public void setOnebest(String onebest) {
        this.onebest = onebest;
    }

    public String getSpeaker() {
        return speaker;
    }

    public void setSpeaker(String speaker) {
        this.speaker = speaker;
    }
}

第四、Luyin,关键的录音方法,调用本地电脑的麦克风,保存录音文件功能

package com.jsbs.fxffjcpt.utils.LuyinHy;

import org.springframework.stereotype.Component;

import javax.sound.sampled.*;
import java.io.File;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.HashMap;
import java.util.Map;

/**
 *
 * @author admin_70
 */
@Component
public class Luyin {
    private static final long serialVersionUID = 1L;
    private static AudioFormat audioFormat;
    private static TargetDataLine targetDataLine;
    private static long starttime;
    private static String filepath= "C:\\Users\\chenjiaxing\\Desktop\\bs\\save\\";


    public static void main(String args[]) {
       // new Luyin();
    }


    /***停止录音*/
    public void stopLuyin(){
    	targetDataLine.stop();
    	targetDataLine.close();
    	System.out.println("---------停止录音----------录音了"+(System.currentTimeMillis()-starttime)/1000+"秒!");
	}


    /***开启录音线程*/
    public Map captureAudio(String hyid){
		Map<String,String> resultMap=new HashMap<>();
    	//随机文件名
		Date date = new Date(System.currentTimeMillis());
		SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyyMMddHHmmss");
		String fileName = simpleDateFormat.format(date);
	   try {
			System.out.println("---------------开启录音线程--------------------");
			starttime = System.currentTimeMillis();
			audioFormat = getAudioFormat();//构造具有线性 PCM 编码和给定参数的 AudioFormat。
			DataLine.Info dataLineInfo = new DataLine.Info(TargetDataLine.class, audioFormat);
					//根据指定信息构造数据行的信息对象,这些信息包括单个音频格式。此构造方法通常由应用程序用于描述所需的行。
					//lineClass - 该信息对象所描述的数据行的类
					//format - 所需的格式
			targetDataLine = (TargetDataLine) AudioSystem.getLine(dataLineInfo);
					//如果请求 DataLine,且 info 是 DataLine.Info 的实例(至少指定一种完全限定的音频格式),
					//上一个数据行将用作返回的 DataLine 的默认格式。

			//开启线程
			new CaptureThread(hyid,fileName).start();
			resultMap.put("code","200");
			resultMap.put("result",fileName);
		} catch (Exception e){
			e.printStackTrace();
			resultMap.put("code","400");
			resultMap.put("result",e.getMessage());
		}
		return resultMap;
    }

    private AudioFormat getAudioFormat() {
		float sampleRate = 8000F;
		// 8000,11025,16000,22050,44100 采样率
		int sampleSizeInBits = 16;
		// 8,16 每个样本中的位数
		int channels = 2;
		// 1,2 信道数(单声道为 1,立体声为 2,等等)
		boolean signed = true;
		// true,false
		boolean bigEndian = false;
		// true,false 指示是以 big-endian 顺序还是以 little-endian 顺序存储音频数据。
		return new AudioFormat(sampleRate, sampleSizeInBits, channels, signed,
				bigEndian);//构造具有线性 PCM 编码和给定参数的 AudioFormat。
	}

    public class CaptureThread extends Thread {

    	private String hyid;

    	private String fileName;

    	public CaptureThread(String hyid,String fileName)
		{
			this.hyid = hyid;
			this.fileName=fileName;
		}

		public void run() {
			//指定的文件类型
			AudioFileFormat.Type  fileType = AudioFileFormat.Type.WAVE;

			 //设置文件夹扩展名
			String fName = filepath+hyid;
			 // 输出的文件流
			File sf=new File(fName);
			if(!sf.exists()){
				sf.mkdirs();
			}

			File audioFile=new File(sf.getPath()+"\\"+fileName+".wav");

			//根据选择的单选按钮。
			try {
				targetDataLine.open(audioFormat);
				//format - 所需音频格式
				targetDataLine.start();
				//当开始音频捕获或回放时,生成 START 事件。
				AudioSystem.write(new AudioInputStream(targetDataLine),fileType, audioFile);
				//new AudioInputStream(TargetDataLine line):构造从指示的目标数据行读取数据的音频输入流。该流的格式与目标数据行的格式相同,line - 此流从中获得数据的目标数据行。
				//stream - 包含要写入文件的音频数据的音频输入流
				//fileType - 要写入的音频文件的种类
				//out - 应将文件数据写入其中的外部文件
			} catch (Exception e) {
				e.printStackTrace();
			}
		}
	}
}

第五、TxtWriteUtil,txt文件流保存,用于保存语音转写后的会议纪要。

package com.jsbs.fxffjcpt.utils.LuyinHy;

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileWriter;
import java.io.IOException;

public class TxtWriteUtil {

    public static void main(String[] args) {
        String content="哎哎哎111222";
        //write(content);
    }


    public static void write(String path,String content){
        //替换全路径
        String filepath="";
        if(path.contains(".wav")){
           filepath= path.replace("wav","txt");
        }else if(path.contains(".pcm")){
           filepath= path.replace("pcm","txt");
        }else if(path.contains(".mp3")){
           filepath= path.replace("mp3","txt");
        }
        //*************************写入************
        try {
             // 输出的文件流
            File sf=new File(filepath);
            if(!sf.exists()){
                sf.createNewFile();
            }
            FileWriter fw = new FileWriter(sf);
            BufferedWriter bw = new BufferedWriter(fw);
            bw.write(content);

            System.out.println("写入---------"+content);
            bw.flush();
            bw.close();
            fw.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }

}

第六、语音转写sdk,maven配置,这里的sdk需要放到resources目录下,自定义配置

<!--语音转写 SDK-->
    <dependency>
        <groupId>com.iflytek.msp.lfasr</groupId>
        <artifactId>lfasr-sdk</artifactId>
        <version>3.0.1</version>
        <scope>system</scope>
        <systemPath>${project.basedir}/src/main/resources/lib/lfasr-sdk-3.0.1.jar</systemPath>
    </dependency>
     <!--第三方依赖包-->
    <dependency>
        <groupId>com.alibaba</groupId>
        <artifactId>fastjson</artifactId>
        <version>1.2.67</version>
        <scope>compile</scope>
    </dependency>
    <dependency>
        <groupId>log4j</groupId>
        <artifactId>log4j</artifactId>
        <version>1.2.17</version>
    </dependency>
    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpmime</artifactId>
        <version>4.5</version>
    </dependency>`

如此便可实现录音以及会议既要功能,代码中有些是用于调用别人接口联调的,可能会出现异常,仅供参考。
