How the PlayStation Eye connects your hands and voice to the PlayStation 4

One advantage that I believe MS has in this area is that they have built the X1 with Kinect as the means of doing voice navigation. The X1 has dedicated audio hardware chips to do all that processing without out taxing the CPU. From what we have seen so far for the PS4, Sony does not have this type of setup. This could mean that the CPU would need to do a lot of work and if this is done in game could have an effect on performance.

Another area that MS has a head-start is in the voice recognition. MS has been doing this for a long time even before you toss in Kinect. Voice recognition is a touchy technology when you do international and even local with a lot of different accents.

I believe there will definitely be things the PSeye will be able to do because it has a camera and Audio chip array like Kinect. Without the depth sensor, true mapping of body and environments will not be something it can do. The PSeye will be very dependent on lighting within your home which I can tell you from my experience is something that breaks both the PSeye and the first Kinect.

It should be interesting to see what Sony does with the 2 cameras. Will we see some 3D type of camera features. I am hoping for something unique to get me to purchase the PSeye again.

PS4 also has dedicated Audio unit for processing along with chip for background processing which can also be used for this.

Digital Foundry: Is there dedicated audio processing hardware within the PlayStation 4? What can it do?

Mark Cerny: There's dedicated audio hardware. The principal thing that it does is that it compresses and decompresses audio streams, various formats. So some of that is for the games - you'll have many, many audio streams in MP3 or another format and the hardware will take care of that for you. Or, on the system side for example, audio chat - the compression and decompression of that.
