Nicla Voice supports wake words, and I am wondering while the Nicla is actively listening with the following methods:
NDP.turnOnMicrophone();
and
NDP.interrupts();
which will match words with the NDP.onMatch(eventTriggered)
method, is it still consuming energy while we are switching on the microphone and waiting for an interrupt?
if so, what's the advantage of the "wake-up words" advertised by Nicla Voice - how do we make full use of this advantage of low power while waiting for wake-up words?
