Amazon employs thousands of people to listen to voice recordings captured by Echo speakers in an effort to improve the software, according to Bloomberg.
The process: The Alexa voice review team includes both contractors and full-time Amazon staff working in offices around the world, including Boston, India, Romania, and Costa Rica. Each reviewer is expected to check about 1,000 audio files in each shift, two of the workers told Bloomberg. The recordings are transcribed, annotated, and fed back in hopes of improving Alexa, the software that powers Echo devices.
