questo è il codice di prova che sto utilizzando:
/**
EasyVR Tester
Dump contents of attached EasyVR module
and exercise it with playback and recognition.
Serial monitor can be used to send a few basic commands:
'c' - cycles through available command groups
'b' - cycles through built-in word sets
's123.' - play back sound 123 if available (or beep)
With EasyVR Shield, the green LED is ON while the module
is listening (using pin IO1 of EasyVR).
Successful recognition is acknowledged with a beep.
Details are displayed on the serial monitor window.
