我錄了一段音存儲在這個test.m4a文件里，語音內容為"測試一下Netweaver對于并發請求的響應性能"。

使用如下Java代碼進行測試：

package com.iflytek.msp.lfasr;import java.util.HashMap; import org.apache.log4j.Logger; import com.alibaba.fastjson.JSON; import com.iflytek.msp.cpdb.lfasr.client.LfasrClientImp; import com.iflytek.msp.cpdb.lfasr.exception.LfasrException; import com.iflytek.msp.cpdb.lfasr.model.LfasrType; import com.iflytek.msp.cpdb.lfasr.model.Message; import com.iflytek.msp.cpdb.lfasr.model.ProgressStatus;// SDK document: http://www.xfyun.cn/doccenter/lfasr#go_sdk_doc_v2 public class TestLfasr {// original media pathprivate static final String local_file = "c:\\temp\\test.m4a";private static final LfasrType type = LfasrType.LFASR_STANDARD_RECORDED_AUDIO;private static int sleepSecond = 20;public static void main(String[] args) {LfasrClientImp lc = null;try {lc = LfasrClientImp.initLfasrClient();} catch (LfasrException e) {Message initMsg = JSON.parseObject(e.getMessage(), Message.class);System.out.println("ecode=" + initMsg.getErr_no());System.out.println("failed=" + initMsg.getFailed());}// get upload task idString task_id = "";HashMap<String, String> params = new HashMap<>();params.put("has_participle", "true");try {Message uploadMsg = lc.lfasrUpload(local_file, type, params);int ok = uploadMsg.getOk();if (ok == 0) {task_id = uploadMsg.getData();System.out.println("task_id=" + task_id);} else {System.out.println("ecode=" + uploadMsg.getErr_no());System.out.println("failed=" + uploadMsg.getFailed());}} catch (LfasrException e) {Message uploadMsg = JSON.parseObject(e.getMessage(), Message.class);System.out.println("ecode=" + uploadMsg.getErr_no());System.out.println("failed=" + uploadMsg.getFailed()); }while (true) {try {Thread.sleep(sleepSecond * 1000);System.out.println("waiting ...");} catch (InterruptedException e) {}try {Message progressMsg = lc.lfasrGetProgress(task_id);if (progressMsg.getOk() != 0) {System.out.println("task was fail. task_id:" + task_id);System.out.println("ecode=" + progressMsg.getErr_no());System.out.println("failed=" + progressMsg.getFailed());continue;} else {ProgressStatus progressStatus = JSON.parseObject(progressMsg.getData(), ProgressStatus.class);if (progressStatus.getStatus() == 9) {System.out.println("task was completed. task_id:" + task_id);break; } else {System.out.println("task was incomplete. task_id:" + task_id + ", status:" + progressStatus.getDesc());continue;}}} catch (LfasrException e) {Message progressMsg = JSON.parseObject(e.getMessage(), Message.class);System.out.println("ecode=" + progressMsg.getErr_no());System.out.println("failed=" + progressMsg.getFailed());}}try {Message resultMsg = lc.lfasrGetResult(task_id);System.out.println(resultMsg.getData());if (resultMsg.getOk() == 0) {System.out.println(resultMsg.getData());} else {System.out.println("ecode=" + resultMsg.getErr_no());System.out.println("failed=" + resultMsg.getFailed());}} catch (LfasrException e) {Message resultMsg = JSON.parseObject(e.getMessage(), Message.class);System.out.println("ecode=" + resultMsg.getErr_no());System.out.println("failed=" + resultMsg.getFailed());}} }

測試結果

(1) 所有中文均能成功轉成文字; 但英文Netweaver的語音轉換成了Net ball

(2) 智能分詞也能按照期望工作，比如“測試一下”成功地分詞成了“測試”和“一下”。
