That makes sense. So, given that this is data it's users have an obvious interest in keeping private, Facebook could at least inform of this. The only reason I could imagine they aren't doing this is that their voice recognition isn't used for any released products. I think that's a viable theory of what they would be doing with the voice data. EDIT: User 'crucifiction' makes a good point about needing the transcript to use it for voice recognition. So, who knows. It doesn't in any sense justify collecting data and being so elusive about their intent. We naturally have reason to get the impression that Facebook just wants the data, will try anything it can to keep collecting it until so much energy has been invested in the PR issues that the collection has an attributable effect on their market. But maybe they are using the voice data to change the world for the better and bring people together yada yada! :)
