Cool, but scary: New Google AI tech can isolate a single voice in a crowd

It's hard enough for us to keep track of who's talking in a loud or crowded party, imagine how difficult it is for automated systems to follow. Speech recognition at a reasonable quality is really only something that's been mastered in the last decade or two, add in conflicting sounds as people talk over each other, and an already tricky problem becomes much harder.

Fortunately (or unfortunately) for us, researchers at Google have been working on isolating sources of audio like speech in videos, and the results they showed off yesterday are kind incredible and simultaneously terrifying.

Google's Emoji Scavenger Hunt is a browser-based game that tries to make machine learning fun and accessible

"Machine learning" and "neural network" are familiar terms to anyone who follows what Google is up to these days, but they may not be the most accessible or comprehensible concepts for the masses. And that's fine — you don't need to have a firm grasp of machine learning to enjoy better photos or keyboards, for instance. Still, Google has been quietly showcasing ways for users to get more hands-on with these concepts, and the latest such experiment is a game called Emoji Scavenger Hunt.

Google's new Cloud Text-to-Speech platform incorporates DeepMind's WaveNet technology for more natural sounding voices

Back in December last year, we looked in-depth at the work Google has been doing to improve text-to-speech and other artificial language use cases. Artificial voice synthesis can be much more powerful and impressive thanks to WaveNet neural network technology, developed by Alphabet subsidiary DeepMind. It's been used to make the Google Assistant sound more natural, and now makes up part of a whole new product: Cloud Text-to-Speech.

Rainforest Connection is fighting deforestation with old phones and machine learning

Machine learning is pretty cool—in fact, the only computer science course I took in college was related to it. So we tend to get excited by novel uses for the technology here at Android Police, and in a recent post to Google's blog, a company called Rainforest Connection came up with an interesting application: Deforestation.

Android P feature spotlight: Google improves neural network API for machine learning and AI developers

Last year, Google introduced a new neural networks API in Android 8.1 Oreo that provided developers with hardware-backed tools for machine learning. Now, with Android P, Google is expanding the API to support nine new operations. Pixel 2 devices will also have support for Qualcomm's Hexagon HVX driver, giving developers further improvements in performance on those devices.

Google releases huge HDR+ image dataset for researchers

Google's HDR+ image processing is almost magical at times, and it's all thanks to machine learning. Just a few years ago, Google's cameras were below average, but the Pixel changed all that with refined image processing algorithms. Now, Google is giving other research teams a chance to come up with their own version of HDR+ and compare it to Google's. It's giving away thousands of images in a gigantic data set, and you can check it out now.

[Update: Rolling out now] Canary Vision offers AI-powered person detection capabilities for free and paid users

It's been a bit of a bumpy road for Canary and its connected security cameras. While Rita had mostly nice things to say about the all-in-one camera in her review, the company has since done its best to annoy users (particularly those on the free tier) by changing its subscription model and then backtracking slightly. Perhaps some new features will go some way to win back the trust of its users.

[Update: All gone] Google Clips now available in the Google Store, but deliveries aren't expected until March

Three months ago Google announced the Google Clips, a tiny clip-on camera powered by some impressive machine learning technology. The idea behind it was that rather than require you to choose when to take a photo, you could trust the device to make that decision itself, so parents hoping to capture special moments with their kids don't also have to take themselves out of the moment to do it. And today you can finally order one, though delivery dates are currently set as far out as March.

Twitter is using neural networks to improve photo cropping

Twitter doesn't show full photos when they appear in the stream—you need to tap to expand the whole image. Unfortunately, the cropped version of the photo is often framed awkwardly because it's just the middle section of the image. Twitter is solving that problem with a neural network that can understand the composition of your images.

[Compress this!] Google issues a machine learning challenge to build a better JPEG

When you navigate to a website on your expensive new Android device, or try to view an image that someone has sent you on your gorgeous Super AMOLED Quad HD display, the last thing you want is to find yourself standing there, waiting for a progress bar to crawl across the screen, or to squint angrily at the spinning loading icon as it sputters.

(Did you know that the loading icon is called a “throbber”? I just found out, and I’m now stuck on the idea of a “sputtering throbber.” That’s neither here nor there.)
