App Listens for Danger When You�re Not Paying AttentionVery cool idea! Posted by DaveH at February 27, 2014 1:50 PM
A startup is developing machine-learning technology that mimics the way the ear works, which it believes will make it easier for smartphones and wearable devices to constantly listen for sounds of danger.
One Llama will show some of its capabilities in an app called Audio Aware, which is meant to alert hard-of-hearing smartphone users and �distracted walkers� (an issue previously explored in �Safe Texting While Walking? Soon There May be an App for That�). The app, planned for release in March, will run in the background on an Android smartphone, detecting sounds like screeching tires and wailing sirens and alerting you to them by interrupting the music you�re listening to, for instance. The app will arrive with knowledge of a number of perilous sounds, and users will be able to add their own sounds to the app and share them with other people.
One Llama hopes Audio Aware will pique interest among makers of wearable gadgets, who could bake the technology into smart glasses, smart watches, and fitness trackers. In those devices, Audio Aware could do more than just be alert to dangers: it could monitor health conditions, workouts, or even locations by paying attention to the sounds you make and the noises around you. Bird watchers might want to use it to home in on the differences between, say, a male chipping sparrow and a dark-eyed junco.
