Amazon staff listen to customers' Alexa recordings, report says

When Amazon customers speak to Alexa, the company's AI-powered voice assistant, they may be heard by more people than they expect, according to a report. Amazon employees around the world regularly listen to recordings from the company's smart speakers as part of the development process for new services, Bloomberg News reports. Some transcribe artist names, linking them to specific musicians in the company's database; others listen to the entire recorded command, comparing it with what the automated systems heard and the response they offered, in order to check the quality of the company's software. Technically, users have given permission for the human verification: the company makes clear that it uses data "to train our speech recognition and natural language understanding systems", and gives users the chance to opt out. But the company doesn't explicitly say that the training will involve workers in America, India, Costa Rica, and more nations around the world listening to those recordings.
