Hi there

Just a quick input, if i could code better, i would do it instantly:

There is a tool called voicebot, that can trigger keys or keycombos via voice activation.
It would be cool to link voice activation to KSP much deeper than actually possible, due to the limitation of KSP keys, it can't do modifier keys such as the command or ALT key right out of the box.

I see potential there for Mechjeb, to do some things like SAS controlls, bring up the various modules like docking autopilot etc.

if the mechjeb interface would support tabulator and arrow keys to navigate, one could even programm macros in voicebot.

for example; set apo on next per to 300km, would look like this:
"command set navigation apo" -> opens node planner, tabs to dropdown and chooses set node at apo
"set 300km" -> enters 300 into focused input
"engage node now" -> tabs to autowarp, sends a space key to check the box, tabs back to the execute node button and hits it with another space
-operation done without touching anything, you could even mimic a role in the game, like commander or navigator etc. by just adjusting the input and sequenceing.

i used this tool very successful for commandeering submarine simulators, it would open up possibilities for VR as well, as it's a bit nittigritty to interface with the more complex actions. but even just like on a tv it is awsome to play a game, able to controll it with voice.

IMHO it would be killer for KSP

Cheers

PS. there was a mod called voice commander for KSP which uses windows recognition, but i find VB is better, plus you can play custom sounds and interact on a bit deeper level. I hooked it up to some original voicerecordings from nasa missions, that way i can sequence a start just like it happend, going over the checklist and everything, including booster and other stage separation - awsome stuff
if you go as far as want to pick this up, incooperate it so far that also a external controller could be used with mechjeb, i would work togeter with you to cover the fabrication of a prototype for a hardware controller as well. here you find my early prototypes:

The offer would be that the finished product would be made for everyone who is involved in it (as long as there are not too many devs in your team :D )
