Listening to their first Ok Google voice search might bring a smile on the faces of many users. However, it is also a reminder of just how much information Google collects about users. So it's not just what people type on their smartphones, but even what they say that Google keeps a track of.
"Google records your voice and other audio, plus a few seconds before, when you use audio activations like-- saying commands like "Ok Google" or tapping the microphone icon. Your audio is saved to your account only when you're signed in and voice & audio activity is turned on. However, not all apps support saving audio to your account," explains Google.
