最近项目要用到语音识别的功能，网上找别人写的都不行，二话不说直接去讯飞官网注册下载了一个sdk，但是个人觉得sdk中并不是很明确的能运行实现功能，于是自己参考下载的sdk中的代码做了一个改动和封装。添加了一个配置文件，基本功能都能实现运行了。下面是我测试写的一个语音转文字的例子
第一：首先在官网上注册下载sdk后之后每一个sdk中都会对应一个apppid和secret key，在我的应用中就会找到（注意新手很难找到对应的secret key,我也是弄了很久，实在找不到可以留言给我）
在下载的sdk中会有对应的jar版本。我的lib是2.0的版本
第二步
我在测试实例中加了一个log4j.properties,代码如下：
log4j.rootLogger=INFO, Console,file
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%p][%d{yyyy-MM-dd HH\:mm\:ss,SSS}][%l]%m%n
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=logs/lfasr-sdk-client.log
log4j.appender.file.MaxFileSize=128MB
log4j.appender.file.MaxBackupIndex=50
log4j.appender.file.Append=true
log4j.appender.file.Threshold=INFO
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} [%5p] %l - %m%n
配置文件config.properties
# APP ID
app_id=“写你申请sdk时候的apppid”
# secret key
secret_key='写你申请sdk时候的secret key"
# we support both http and https prototype
lfasr_host=http://lfasr.xfyun.cn/lfasr/api
# file piece size, recommended between 128KB and 10,240KB
#读取文件大小的最大显示
file_piece_size=524288
# store path: this is not the store path for the result json file, but the path for the file piece during upload
store_path=语音识别的文件的根目录
最后测试代码
