Google Assistant is the most accurate voice assistant on the market beating out Samsung's Bixby, Amazon's Alexa and Apple's Siri. A new report says the company has humans listening to recorded search queries to help improve the accuracy of its assistant. 

Google has contractors listening to recordings from Google Assistant users according to Belgium-based VRT NWS. A contractor provided the news outlet with more than a thousand recordings of people using Google Home and the Google Assistant app to answer questions and conduct searches. There were also recordings from when the assistant was accidentally triggered. 

The Google contractor says their job entails listening to the recordings to check the accuracy of the assistant listening to users speaking in Dutch. Contractors review the script of the recorded query and confirm it matches with the voice recording. There are reportedly thousands of Google employees worldwide listening to audio excerpts via a secure login in the company's Crowdsource app. 

In April, a report found Amazon uses human workers to listen to Alexa recordings to improve the assistant's accuracy. 

Google didn't immediately respond to a request for comment.
