There are plenty of iPod cradles that let you remote control the device, some built-in to cars, but Direct Voxx has come up with the Muso that lets you do it by voice. It's an interesting bit of kit that doesn't require training to understand you, and lets you demand particular tracks, scan through playlists, pause and resume playing music just by speaking in natural language like "play California Dreaming by the Mamas and the Papas." Check out the video to see it in action.
Pretty impressive, and saves all that fiddling around with buttons when you should be busy controlling your car. It's got background noise suppression, so apparently it can cope with driving noise. And its independent battery runs it for 10 hours, without affecting the iPod.
There's just one flaw: its price. At US$159 it's more than a 4GB nano itself, and that seems a little crazy. They are planning on releasing new versions for other iPods and the iPhone "as soon as possible," but this one will be out in December. [DirectVoxx]
