Xiaomi's voice is intermittent after upgrading to 14.

1. After the system is updated, the equipment fails to operate. It is best to update and upgrade the system and disinfect the mobile phone in time, which will make it more smooth to use.

2. There is no sound due to the problem of the other party's mobile phone, such as receiver failure or system problem. You can use Xiaomi mobile phone to call different contacts to confirm.
