10. Recording Tips
For better recording results, it is necessary to provide conditions with lowest amounts of ambient noise and speaker distance from
the microphone in the range from 10 to 20cm.
If there are problems with the voice command detection, please record it several times due to the pronounciation diversity.
It is
mandatory
to play back the recorded voice command in order to hear if some ambient noise was recorded also.

board is placed on a surface that doesn’t transfer mechanical vibrations.
This is a speaker dependent system.
If there are more users, each person should record voice commands separately, due to the
pronounciation diversity.
Number of voice commands that can be recorded depend on their lengths, typically more than 200 for the voice command length

board, not the computer, so there is no need to connect
