Detailed Baidu speech recognition api document

First download the python SDK, you can install it with python setup.py install

# 引入Speech SDK
from aip import AipSpeech

# 定义常量
APP_ID = '你的 App ID'
API_KEY = '你的 API Key'
SECRET_KEY = '你的 Secret Key'

# 初始化AipSpeech对象
aipSpeech = AipSpeech(APP_ID, API_KEY, SECRET_KEY)

In the above code, the constant APP_ID is created in the Baidu Cloud console. The constants API_KEY and SECRET_KEY are assigned to the user by the system after the application is created. They are both strings for identification. Users perform signature verification for access, which can be viewed in the application list in the AI ​​service console.
