Menlo Park (AP) - Facebook has employees listen to selected footage of users from his chat service Messenger and get typed. Affected by users who had turned on the transcription function for language entertainment, Facebook said the financial service Bloomberg. The task of the employees was to check whether the software had correctly understood the spoken sentences. The news had been anonymized. The typing was discontinued more than a week ago. Also at Amazon, Apple and Google, there was a similar practice in the past.
