IMPORTANT. You will need to be using RightBooth version 7.6.28 (or newer) in order to implement the solution described in this article.
I had an interesting email chat with one of my RightBooth users about the consistency of the Voice Recognition feature. He was simply wanting his event users to say the word 'cheese' in order to trigger the taking of a photo.
So he created a photo capture event and on his event Start screen he added the word 'cheese' as a label item having the action 'Next screen', and then he turned on the Voice Recognition feature.
But when playing the event he was finding that the spoken word 'cheese' was not always being recognised as such, and this led to our email chat.
On testing this myself, I discovered that when speaking the word 'cheese', the recognition engine was occasionally (and incorrectly) recognising my spoken word as one of the following similar sounding words:
Now this recognition inconsistency is actually inherent in the Microsoft Voice Recognition system and it makes RightBooth appear to ignore quite a few spoken words.
So here is my suggestion to improve the reliability:
Now when any user says 'cheese' and it is incorrectly recognised as one of the similar sounding words, RightBooth will still accept the word as a voice command and will progress to the next screen as intended, effectively making the voice recognition more reliable and consistent.
