Noise level: Minimal sound volume level that can trigger a
voice command recognition. Lower values require quieter
pronunciation, resulting in higher noise/hiss sensitivity.
On the contrary, higher level values require louder
pronounciation and they are less sensitive to noise/hiss.
We recommend that you keep auto detection enabled. That
way the SpeakUp Click board will measure the noise level,
and perform noise calibration automatically. Auto detection
can last a bit longer, usually around 10 seconds. Sudden
changes in sound levels will lengthen the time of calibration
and will result in improper sound level values.
Notify master: Notifies the master (MCU or PC) when the
voice command is recognized by sending a 16-bit index
number of voice command via chosen communication
interface (UART or USB).
Data rate: Sets the speed used for sending data to the
master (MCU or PC).
Pin Aliases And Initial Pin States
In this section, you can rename GPIO pins according
to your needs and set their starting conditions. The
new GPIO pin aliases will be applied in the main
window too. Set the corresponding initial GPIO pin
state in the Initial Pin States section. Condition can
be either low (logical 0) or high (logical 1).
