has used its Ignite 2019 conference in Orlando to show off an AI-powered feature for . Called Voice Enhance, it reduces background noise, even in industrial scenarios.

In the short demo below, you can notice a very significant difference. The AI cuts out the beeping from a reversing vehicle, as well as the rumbling of objects being moved. The result sounds slightly muffled, as with most noise reduction efforts, but it's a vast improvement in clarity.

The solution was developed in collaboration with Asia, with the hope of removing disruption in the workplace.

“Microsoft innovations in AI are making products more intelligent and powerful, so organizations can empower their employees to be more productive with less distraction,” said Hsiao-Wuen Hon, CVP, Microsoft Research Asia.

The feature won't become generally available until Q2 CY20, but there are a couple of other Stream features to keep you occupied in the meantime. Microsoft launched Additional languages for transcripts and captions at Ignite and the ability to record and edit on mobile will come in Q1.

The new languages for auto-generated transcripts include:

  • Chinese (Simplified)
  • French
  • German
  • Italian
  • Japanese
  • Portuguese (Brazillian)

Finally, users will be able to build PowerApps that use integrated Stream video. The addition of Stream to the no-code app builder means users will be able to search for keywords within videos and more.

With these improvements, Microsoft is further pushing users to migrate from Office 365 video. Eventually, when all users have transitioned, it will shutter the 365 service.

The company also revealed the app will support Robotic process automation (RPA). With this integration, the app can support UI flows and become an end-to-end automation tool. You can take advantage of an RPA software trial to try out with the app, if you are interested in this new technology.
