我錄了一段音儲存在這個test.m4a檔案裡，語音內容為"測試一下Netweaver對於併發請求的響應效能"。

使用如下Java程式碼進行測試：

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_v2public class TestLfasr {    // original media path

    public static void main(String[] args) {

            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());
        }

            } 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 {

                    }
                }
            } catch (LfasrException e) {

                System.out.println("ecode=" + progressMsg.getErr_no());
                System.out.println("failed=" + progressMsg.getFailed());
            }
        }        try {

            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) 智慧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”。
