Intended to introduce 'signal processing' though the filtering of raw voice data. - A simple addition calculator which takes in a number (0-5) 'plus' another number (0-5). -The raw data from speech needs to be filtered to remove the blank spaces, this filtered info is then used to produce some simple addition- the panda sprite will give you the answer -the NeuroMaker hand will also output the answer for the addition as fingers, for any number larger than 5 it gives you two hand signs- for example, number 7 represented as 5 fingers up, all fingers go down, 2 fingers up.
