@ransanti was actually on the right path.
So here’s what I found out.
I did absolutely everything I could find online to fix this “understanding problem”; everything from cleaning mics, relocating, even tilting — nothing worked.
I called amazon to see if it was malfunctioning, and had a super interesting chat with a guy over there. So this is what he told me:
“The echo devices learn your speech patterns more and more as you speak to them; you’ll even occasionally hear it ask ‘did you have to ask for this more then once?’ Or ‘did I do what you expected?’ — This is Alexa learning. But what happens over time, depending on its location in your home and it’s surroundings is, it will start incorporating the background noise into your speech patterns.
So for example, if you have your echo device close to a TV or Stereo speaker, the echo will hear you say a command, and also hear whatever is making noise as well and combine them into the speech algorithm (if it hears it frequently enough when saying that command). Even barking dogs, loud children, or even loud traffic outside a window you may have your echo sitting on will pick up those sounds.
So if whenever you’ve said the command “Alexa, turn on living room lights” and it’s heard a repetitive and frequent sound along with that command, it’ll start associating it with your speech pattern over a long period of time.
The problem you might be having is you’re now going out of your way to make it silent and you’re speaking slower then usual to give the command; your echos are looking for those background sounds because they’ve been included so many times over the years.”
He went on a bit more, but you get the idea. I had my living room echo about 5 feet from a tv which is always on. Not loud mind you, but loud enough to hear. I haven’t reset anything in the entire time I’ve owned these echos. We quickly reset the voice prints and other learned algorithms, and boom, she understands me clear as day now no matter what I ask. It was a day and night difference from before. We did this 2 days ago and I haven’t had to repeat myself once yet.
So, if you’re having trouble with your echos understanding you, this might be the solution for you. But he did say it’s somewhat rare to get this bad. Alexa is designed to ignore a lot of things, including background noise during commands. It was more of a fluke that a lot of the exact same sounds were playing when I said things over the years, which lead to it attributing them to my speech pattern.
But hey, problem solved now for me. I’m happy again.
