My echo absolutely became less accurate month after month. Simple commands like “turn off the lights” would be 50/50. Very low-value technology and it certainly gives one pause about the feasibility of AI when something so basic with so much capital and years of effort is still fairly poor.
And there is latency issue too, you won't get response very fast. If you look for <0.5s latency or the answer, you need to try something like Vosk probably.
