java 调用科大讯飞 实现会议录音 语音转写会议既要功能

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。地址如下：

/doc/platform/quickguide.html。

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。

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 mon.annotation.Excel;import mon.core.domain.BaseEntity;import mons.lang3.builder.ToStringBuilder;import mons.lang3.builder.ToStringStyle;import java.util.Date;/*** 组织生活-会议对象 og_meet* * @author Donfei* @date -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.ponent;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*/@Componentpublic 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,falseboolean 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。资源下载：/download/weixin_43832166/19932122
