Facebook&#x27;s explanation:<p>&gt;Myth: The feature listens to and stores your conversations.<p>&gt;Fact: Nope, no matter how interesting your conversation, this feature does not store sound or recordings. Facebook isn’t listening to or storing your conversations.<p>&gt;Here’s how it works: if you choose to turn the feature on, when you write a status update, the app converts any sound into an audio fingerprint on your phone. This fingerprint is sent to our servers to try and match it against our database of audio and TV fingerprints. By design, we do not store fingerprints from your device for any amount of time. And in any event, the fingerprints can’t be reversed into the original audio because they don’t contain enough information.<p>&gt;Myth: Facebook is always listening using your microphone.<p>&gt;Fact: Nope, if you choose to turn this feature on, it will only use your microphone (for 15 seconds) when you’re actually writing a status update to try and match music and TV.<p><a href="http:&#x2F;&#x2F;newsroom.fb.com&#x2F;news&#x2F;2014&#x2F;05&#x2F;a-new-optional-way-to-share-and-discover-music-tv-and-movies&#x2F;" rel="nofollow">http:&#x2F;&#x2F;newsroom.fb.com&#x2F;news&#x2F;2014&#x2F;05&#x2F;a-new-optional-way-to-sh...</a> (via <a href="http:&#x2F;&#x2F;www.computerworld.com&#x2F;article&#x2F;2490090&#x2F;social-media&#x2F;backlash-over-facebook-s--listening--feature-is-a-problem-of-trust.html" rel="nofollow">http:&#x2F;&#x2F;www.computerworld.com&#x2F;article&#x2F;2490090&#x2F;social-media&#x2F;ba...</a>)
