When used on Android, if the speaker is far away from the device, it will not be recognized accurately

We are using it on Android devices. Initially, we used the webSocket server. If the speaker is far away from the device, about 1 meter away, it will be difficult or unrecognizable.
Later, we switched to using the webRtc server, and the effect improved slightly, but it was still not good.
Has anyone encountered a similar situation before?
Is there any way to improve the accuracy of long-distance recognition?

You have to find long-distance model and also you need a very good microphone. Not sure what device are you using but most likely you need a special device.
