Error: No voice recognition in Big Box

[Alex Dubois]

Hi Jason,

Love your work and your livestreams! You've put the love of emulation (and gave me a reason to disappear from society for a few months while I rebuild my collection)

Anyways, here's the issue:

I wanted to try out the voice recognition feature, so I activated it through launchbox, exited out and loaded big box. I used the default microphone/displays setup with my PC out of fear of possible configuration issues were I to send it all through my mike/TV setup a bit farther away (and also because I was a bit excited).

I tried saying "Big box" and "Launch box", to which I received no feedback.

Big box went into attract mode, I figured I must have missed something somewhere so I hit escape to go and look over the options again.

Due to the wheel spinning at the time, it waited a few seconds before exiting into the main menu as expected. I then scrolled down to get to "Exit", where, after a few menu items flashing by, I was greeted with the below error message. Big box did not crash and was fully functional otherwise, I managed to exit properly. Figured I should let you know.

Update: Upon loading launchbox again, it seems that the "Enablevoice recognition" boolean didn't get saved. I had to re-select it through the options menu.

Update 2: Got it working fine now (no more errors), although there is something odd-

If you switch from launchbox to big box by using voice recognition, you are then unable to switch back to launch box from big box by using voice commands due to "This command is only available when in bix box".

Thank you Alex; I believe both of these issues should be fixed for the next beta. :)
