The Google Now voice search for desktop that was showcased at Google I/O 2013 appears to be finally coming to desktops for users who have non-US language settings.
In the latest version of Chrome Canary (36.0.1972.2) you can edit your advanced settings to enable OK Google to start a voice search.
This video needs watching in fullscreen and change settings to 720p as it isn't easy to follow in its current form.
To enable on Chrome OS X
- Open Chrome
- Press CMD+, to open settings
- Scroll to and click on Show Advanced Settings
- Check Enable OK Google to Start a Voice Search
Once enabled you should be able to see 'Say OK Google' in your language in the input box of Google Search when you select a new tab - providing you don't have your new tab page set to go to another URL.
Say OK Google and you will see the familiar animated microphone telling you that it is listening.
There is a slight issue as it doesn't appear to work on the ccTLD currently. You need to be searching from Google.com, although eventually I am sure this will work on your ccTLD but for now you can test it on .com. I have also just realised queries where spoken answers are usually given in English are not given in foreign languages yet, it doesn't even give them back in English. When the languages are available I presume this feature will work on your ccTLD.
