What should I do if my voice is not clear or small when playing on Xiaomi Smart Kids Watch?

Please follow the below methods to check:
1.Confirm whether the process of recording voice messages is interfered by the environmental factors at that time, it is recommended that the mouth is as close as possible to the microphone position of the watch/cell phone during the voice recording process;
2.Possibly the watch is wet, the liquid blocks the microphone hole or speaker hole, or there are other objects blocking the microphone hole or speaker hole; if the watch is wet, please wipe the microphone hole or speaker hole of the watch and then use it again (if the water in the hole can't be wiped off, you can wait for the natural evaporation before using it again), if there are other objects blocking the microphone hole or speaker hole, please remove it and then use it again.
