Generally, shouting commands
at the internet isn't going to get you very far but, if you're just yelling a few destinations and search terms, Chrome extension Chaufr can take you where you need to go. A previous add-on, Speechify, let you speak to fill input fields, but couldn't help you actually navigate the web. Chaufr, on the other hand, lets you simply say the magic word -- "Engadget" -- and it drops you right at our online doorstep. You can also use it to perform searches by saying Wikipedia, Google, Amazon, YouTube, or Yahoo followed by whatever it is you're looking for. It worked well enough in our brief hands-on, but we do have one nit to pick -- activating voice input requires you click on an icon in the tool bar then
click on a microphone in the drop down menu. (Can't a brother get a keyboard shortcut?) You can try it out for yourself by clicking on the source link.
