• Amazon has thousands of workers around the world listening to recordings of conversations between users and the Alexa voice assistant, in the name of improving its ability to understand human speech, according to Bloomberg.
• Amazon tells Bloomberg that it only tasks humans with reviewing "an extremely small sample of Alexa voice recordings."
• The moderators reportedly have a chatroom where they can ask for help, or just share "amusing" recordings.
• The moderators also occasionally hear more upsetting things: Two workers told Bloomberg that they heard a recording of what they believed to be a sexual assault.

A new report from Bloomberg highlights the human labor that goes into making Amazon's Alexa voice assistant - which comes built in to every Amazon Echo speaker - a little smarter.

The company has a mix of contractors and full-time employees all over the globe reviewing and transcribing clips of conversations between users and Alexa, according to Bloomberg. The idea, the report says, is to have humans annotate those interactions, helping identify phrases like "Taylor Swift" that might otherwise be meaningless to the software.

"We only annotate an extremely small sample of Alexa voice recordings in order improve the customer experience. For example, this information helps us train our speech recognition and natural language understanding systems, so Alexa can better understand your requests, and ensure the service works well for everyone," an Amazon spokesman told Bloomberg.

"Employees do not have direct access to information that can identify the person or account as part of this workflow. All information is treated with high confidentiality and we use multi-factor authentication to restrict access, service encryption and audits of our control environment to protect it," the spokesperson said.

The Amazon workers, who number in the thousands, reportedly have a chat room, too, where they can get help when they can't quite make out a word or phrase - or where they can share "amusing" recordings, as Bloomberg puts it.

Additionally, one Amazon worker told Bloomberg that each member of this team will listen to as many as 100 clips a day where Alexa was mistakenly or unintentionally activated. Bloomberg reports that one of these workers will review as many as 1,000 clips in a nine-hour shift.

The report indicates, however, that the content in those recordings can be quite serious: Two workers that Bloomberg spoke to detailed what they believed to be a recording of a sexual assault. Separately, two workers told Bloomberg that they were given guidance that Amazon didn't consider it its place to intervene in cases like these.

Amazon did not immediately return a request for comment from Business Insider.
