Is there a good microphone array when integrating Baidu speech recognition?

problem description

to develop an intelligent robot, speech recognition using Baidu SDK, works well in quiet scenes, but the recognition effect is very poor in a messy voice environment. I use an ordinary microphone. Do you have some encapsulated microphone arrays that can be integrated to suppress noise or far-field recognition?
