dw reporter carl nasman is here with me. shock, horror, who would have thought? ll us, what have you found out? carl: there were all those rumors that facebook was listening to our conversations. it turns out in a way that was true. it wasn't quite what we thought was. there were rumors they were listening to our phones, giving us these creepy personal advertisements based on our conversations. it was actually for a different purpose. according to bloomberg, facebook hired an outside company to listen to and transcribe audio clips from users' conversations. facebook says this was done to improve its artificial intelligence. and this was basically something that would automatically change your audio into text inside of facebook messenger. this is the feature we are talking about right here. you can see how this works. if you turned on v voice transcription anand sent a fried an audio message, your message would automatically be turned into text. just like here, in this case it is a grocery list. of course we know artificial intelligence is not always very accurate.
