AI sound recognition will help protect your home from burglary


The company has created a sound map, comprising over six million audio files. It looks like a rainbow honeycomb: it visually represents similar sounds grouped together in colored blocks, or “tonal islands”. Mitchell suggests turning down the volume when he arrives on the “Shattering” Island. “This ‘pause noise’ was coming from a dining room,” he says. “[The glass being broken] was a laminated wood glass panel – and there are six other types of “break” associated with it.

Alexandria’s audio sample data pool had to be built from scratch. The stock sounds used in the movies were unnecessary, as they are not true to their real world counterparts. “If you are going to see the last Avengers movie, I’m sure the Hulk is going to drop something on a car, ”Mitchell says.

“This car alarm going off is not a real car alarm.” That sound would lead the AI ​​to a false reality: dire, if you were to detect someone breaking into a car. Therefore, the company built its own lab to capture raw sounds and sent teams to record others in various environments. They even relied on networks of volunteers to enter the sound lab or use recorders to capture sounds in the real world.

Audio Analytic’s plans for the future are confidential, but its goals are clear: to continue to develop technology to identify sounds inside and outside the home. And to meet the challenges of birds that sound like alarms. “I doubt evolution conspired just to give me this problem,” Mitchell says. “But it is a problem that must be solved.”
