An anonymous reader writes "Google has launched the Google Voice Search Hotword extension for Chrome, bringing the 'OK Google' feature to the desktop. You can download the new tool, currently in beta, now directly from the Chrome Web Store. Android users with version 4.4 KitKat will recognize the feature: it lets you talk to Google without first clicking or typing. It's completely hands-free, provided you're already on Google.com: just say 'OK Google' and then ask your question." Quick, someone wire Pocketsphinx up to Firefox, or integrate Simon into Krunner.
