python调用腾讯云API语音识别

一、登录腾讯云、开通语音识别接口、获取密钥  登录 - 腾讯云 (tencent.com)

二、打开 API Explorer 语音识别 录音文件识别请求 - API 文档 - 文档中心 - 腾讯云

选择 录音文件请求

三、打开参数说明，按需求填入参数。

 其中Data输入的的是音频文件经过base64编码后得到的string 代码如下

import base64

file1 = open("16k.pcm","rb").read()   # 读取二进制文件
text = base64.b64encode(file1)   # 进行编码
print(text)

将输出结果复制到Data获得TaskId

​

四、将TaskId复制到结果查询窗口的TaskId输入栏中，

​ ​

 识别结果

 ​

 动态界面调试的成功率极低因为复制过程中可能会导致base64编码的文本产生错误，这个仅作为调试。所以上面操作有些是多余的。下面正文开始

填好必要的参数Data先随便填入一个字符后然后复制代码

​

 拷入编译器中

 然后再安装tencentcloud-sdk-python包

在修改一下复制在编译器中的代码，免去复制base64编码的步骤
