The Kinect uses a cheap applications processor. The same used in digital photo frames.

Facts:
*Ps2 games had no problem doing voice control without taking major hits
*PC processors would have absolutely no problem with this, no argument. But it's still exclusive to 360 with Kinect.
*Marvell PXA 168 is an applications processor used for minor tasks. The ps3 would have NO problem doing that, even if it cost the slightest performance hit to do.

Getting into the nitty gritty! It's a dedicated chip for audio.

"TechInsights' teardown uncovered within Kinect a Marvell PXA 168 applications processor, a part usually found in notebook computers."

"Regardless, Microsoft has created a product that takes full advantage of all its components to provide an innovative gaming experience."

Slew of information on the processor specification:

That is a pretty advanced chip for audio processing!

The question isn't if it is possible on other platforms, but if it is worth the effort and cost.

MS provides the hardware necessary (without need to optimize much) and the software to make it work well. After all MS has put in all the work of calibrating the microphones for different environments and tailoring it.

On other platforms, you might have to heavily optimize it, put in a lot of staff and potentially pay a licensing fee for the software.

I've already seen that PDF, and most of those are THEORETICAL top specs for that chip.

And besides, old games STILL used voice commands without issue. And at the very least, PC could have it with little effort.

There are NO feasible excuses here.

Socom 1 and 2 were on PS2 and I don't ever recall giving an inaccurate order in those games.
