This makes me wonder, has anyone found a buffer overflow in the Alexa cue? Meaning that by activating Alexa with the right audio you make the audio processor crash?
Wow. That's a thought. And if you can make it crash, then you can maybe make it run shellcode instead...
I wonder if there's a way to identify audio from speakers. IT might not work for higher end speakers or lower end microphones, but I'm sure the limited frequency range from speakers, and perhaps artifacts of audio compression that might not be noticeable to humans, would identify non-human audio. I've seen a similar approach used for visuals, separating an image at the point of recording based on the type of light so…
I don't know how much of that is directionality and how much is the sound itself. Cats probably hear different frequencies than humans, but as you point out it wouldn't be too hard to make smart devices' microphones sensitive to those frequencies that our devices' speakers don't emit correctly (because humans don't hear them).
I thought that these voice assistants were keyed to people’s individual voices, and their characteristics. Like what VALL-E clones
It specifically seems to recognise the voice based on the wake word - my son an I tested this by having one of us say "Alexa" and then the other saying "who am I?", and it'd consistently give the name of the person who said "Alexa".
No my name is not anything close to Siri. No, I didn’t train ‘Hey, Siri’ in a noisy environment. All I could possibly give for a reason is that I have a deep sonorous voice.
Ok but why she respond still responds to Michael from the TV but not echo when I’m yelling at it the third time trying to set a timer. There’s a reason I’ve switched almost exclusively to Siri.
Today I asked Siri what the temperature was this morning. It told me it doesn’t have access to past weather information. Siri has been available for 12 years… I cannot understand why it hasn’t leaped forward more than it has. Embarrassingly low level of progress IMO, though for some things it still remains best in class.

It always seems like my cat can tell what's from a speaker and what's real. My wife calling to the cat over the phone never triggers any reaction, and the cat will often jump out because of a little noise in the kitchen or outside even though a movie is playing. I don't know how much of that is directionality and how much is the sound itself. Cats probably hear different frequencies than humans, but as you point out…
Meanwhile, I’ve had to disable ‘Hey, Siri’ on my iPhone because it’ll trigger at least 4-5 times a day during normal conversations. No my name is not anything close to Siri. No, I didn’t train ‘Hey, Siri’ in a noisy environment. All I could possibly give for a reason is that I have a deep sonorous voice.

The worst part is that when it’s triggered, it refuses to shut up and be canceled.
Siri is the laughing stock of the “AI assistants” space.
