请求体类型
Accept
application/json;charset=UTF-8
接受的返回类型
X-AppId
项目或应用的唯一标识符
X-TimeStamp
请求的UTC时间戳。需要把时间戳按W3C标准格式化，例如: 2010-01-31T23:59:59Z. (http://www.w3.org/TR/xmlschema-2/#dateTime)。

音频url
alternativeLanguages
可选
候选语种数组，最多支持传入4个候选语种 支持语种

请求签名：
当用户请求Speech Recognition API时，可以使用appId和secretKey对请求做签名，当API收到带签名信息的请求之后，将使用相同的算法验证签名，如果发现签名不一致，API将会返回401给用户。
如果API验证签名一致，且appId对应的用户有权限操作请求的资源，则请求成功，否则API返回401。
通过 HTTP 请求 Header 发送签名
方法: 在请求中加入名为 Authorization 的 Header，值为签名值。如下：
Authorization: Njl86M/jY6zZaZoGhZdGO+GI/8+yGFECusGH1yQHUFE=
签名计算方法
1.构造规范化的请求字符串（Canonicalized Query String）
将请求体JSON字符串以UTF-8字符编码做sha256编码后转换为16进制字符串（注意不是Base64）
CanonicalizedQueryString = hex(sha256(jsonBody))
2.构造被签名字符串 StringToSign ("\n” 代表ASCII里的换行符)
StringToSign = HTTPMethod + "\n" +
HostHeaderInLowercase + "\n" +
HTTPRequestURI + "\n" +
CanonicalizedQueryString <从上一步得到> + "\n" +
"X-AppId:" + SAME_APPID_IN_HEADER + "\n" +
"X-TimeStamp:" + SAME_TIMESTAMP_IN_HEADER
HTTPRequestURI是请求URI的绝对路径，不包含请求串。如果HTTPRequestURI为空，也要保留一个正斜杠 ( / )
使用 HMAC-SHA256 协议创建基于哈希的消息身份验证代码 (HMAC)，然后计算签名。
3.StringToSign作为签名字符串，secretKey作为秘钥，SHA256作为哈希算法
有关 HMAC 的更多信息，请参阅 https://tools.ietf.org/html/rfc2104。
4.将上一步的结果转换为BASE64串
5.将BASE64串放入HTTP请求Header的Authorization
