Hi, I am going to buy the WisBlock Microphone Starter Kit (WisBlock Microphone Starter Kit) and I wonder which is the difference between the RAK4631 with Arduino Open Source and the version with Voice Processing on the core selector.
I will have to do some signal recognition on that module so I don’t really know which one fits my needs the bettee.
Thanks in advance and best regards.
Welcome back to the forum @jjavims
The RAK4631 with Voice Processing comes with a license for Voice processing from Cyberon.
I never used it and I don’t really know the details about it. @geoff might be able to give more details.
Javier,
You will probably want the Arduino version. The Voice Processing version includes a license for our Voice Processing software which can look for keywords (aka triggers).
