Google listens after you say 'OK Google' to your desktop Chrome | ZDNet. If you use the OK Google voice command to search for information on your computer, you should be aware that the recording is sent to Google, which stores it for improving voice recognition. If this bothers you, you can turn it off in Advanced Settings in Chrome. You can tell when it is listening by looking at the microphone icon. If shaded, it is listening. What many don't know is that OK Google, by default, records what you say a few seconds BEFORE you say OK Google, and the OK Google itself, ostensibly to improve the recognition of your voice. You can turn off this feature, and I recommend it. Go to Settings, Advanced, and unclick OK Google if you have it set already. Then, turn it back on and you will be presented with the option to record before OK Google. Uncheck that box. Now, only what you say AFTER OK Google will be recorded. Your searches are stored anyway, until you delete them by clearing the cache; but, of course, Google saves them for a period of time. Be careful out there.
