音频录音文件实现语音转换识别文字最后文档输出结果

实现对mp3等录音文件进行语音识别成文字，最终获取文档格式或者其它定义格式文件，也可以进行提取数据处理逻辑，轻松实现大文件的语音文字转换功能，精准高效便捷...

1. 功能技术：java+阿里云语音识别+OSS文件存储

*注意：文件需要有读写和可下载访问权限

代码实现

配置地域ID、常量、固定值：

// 地域ID，常量，固定值。（根据自己开通地址配置）public static final String REGIONID = "cn-shenzhen";public static final String ENDPOINTNAME = "cn-shenzhen";public static final String PRODUCT = "nls-filetrans";public static final String DOMAIN = "filetrans.cn-shenzhen.aliyuncs.com";public static final String API_VERSION = "2018-08-17";  // 中国站版本// public static final String API_VERSION = "2019-08-23";  // 国际站版本public static final String POST_REQUEST_ACTION = "SubmitTask";public static final String GET_REQUEST_ACTION = "GetTaskResult";// 请求参数public static final String KEY_APP_KEY = "appkey";public static final String KEY_FILE_LINK = "file_link";public static final String KEY_VERSION = "version";public static final String KEY_ENABLE_WORDS = "enable_words";// 响应参数public static final String KEY_TASK = "Task";public static final String KEY_TASK_ID = "TaskId";public static final String KEY_STATUS_TEXT = "StatusText";public static final String KEY_RESULT = "Result";// 状态值public static final String STATUS_SUCCESS = "SUCCESS";private static final String STATUS_RUNNING = "RUNNING";private static final String STATUS_QUEUEING = "QUEUEING";
