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:

• trees
• he's
• she's
• jeez

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:

• On the Event Start screen, add a label item and enter the word 'cheese' AND all the similar sounding words that the engine incorrectly recognises. 
• Note that you must add each word on a separate line in the label item (see image below). 
  
• Set the label item's click action as 'Next screen'.
• Finally, move the label item off the edge of the screen so that it isn't visible to the user when the event plays, like this...

RightBooth version 7.6.27 has been released and contains the following new features and fixes:

1) Add the 'Record audio' checkbox in RightBooth Settings --> Cameras --> Webcam audio.  This allows you to record webcam videos that do not contain an audio track.

2) Allow .wav files to be used as the audio track in the RightBooth Video Enhancements.

3) Add the QR code item to the 'Add items' toolbox in the Screen Editor.  This allows QR codes to be added to event screens with a fixed aspect ratio and a correctly sized white border that improves the ability for QR code scanner apps to identify the QR code.

4) Add the 'Choose when to perform file copy actions' options in Event Designer --> Event files/folders.   These new options allow you to choose at what point in the playing event flow that various file copy actions will occur.  You can choose from the following:

• After creating – Files will be copied or uploaded immediately after the file has been created.
• ‘Show’ screen – Files will be copied or uploaded when the ‘Show’ screen appears. If this choice is selected but you do not include the 'Show' screen in your event, file copy actions will not be performed.
• ‘Options’ screen – Files will be copied or uploaded when the ‘Options’ screen appears.  If this choice is selected but you do not include the 'Options' screen in your event, file copy actions will not be performed.
• After completion – Files will be copied or uploaded when the current user has finished with their current recording session. This normally happens when the event flow proceeds beyond the Options screen in the Screen Editor Screen list. 

Fixes:

• Prevent any Video Enhancement outro video from being clipped when the video recording length is less than the outro video length.
• Allow the Event Wizard to complete when choosing the GoPro camera in the final step of the Wizard.
